Increase your power density with 3DPP®
Low power switching regulators and isolated DC/DC converters need to be cost-effective, despite ever-increasing demands for better electrical performance and improved power density. Manufacturers have responded over time with many form-factors that help with economical manufacturing, often with a minimal component count with transformers and inductors hand-soldered to traditional PCBs resulting in performance and manufacturing compromises. To reduce the PCB footprint, through-hole SIP versions are commonly utilized. However, their inclusion can introduce assembly challenges, as they necessitate combining wave soldering or even hand soldering with the reflow process used for other SMT electronic components on the board.

Increase your power density with 3D Power Packaging®
While millions of through-hole DC/DC converters of this style are sold annually, a long-term objective for RECOM has been to design versions that can be manufactured consistently and efficiently, while also being compatible with modern SMT processes for handling, placement, and soldering. Electrical performance should be enhanced and the parts should have a low profile to match today’s slim-line products. However, the footprint must remain small to realize the advantages of a module over a discrete design. To achieve this, switching regulators and isolated DC/DC converter modules have to utilize the Z direction by integrating 3D packaging and assembly techniques.
RPM internal PCB visualization
The innovative, state of the art manufacturing technologies that RECOM has developed are complemented by advanced circuit and thermal design resulting in highly efficient parts, achieving astonishing power levels at high temperatures, in packages compatible with high speed machine automation for handling placement and soldering. An example is the QFN-packaged RPX series, just 3mm x 5mm x 1.6mm for versions providing 1A and 1.5A output at a programmable voltage from 0.8-30VDC.
While non-isolated DC/DC converters shrink in size as technology advances, isolated parts are restricted by practical and statutory creepage and clearance distances. This gives a minimum footprint size, but RECOM has applied 3D Power Packaging innovation to reduce the height to an absolute minimum. For example, the SOIC-16 RxxCxx series includes the stringent 2MOPP/250VAC medical grade isolation but is just 2.65mm profile.
RECOM parts incorporating 3D Power Packaging technology are ideal for space- and cost-critical applications in industrial, medical, networks, storage, portable equipment, imaging systems, telecoms and ‘Point-of-Load’ power for processors and FPGAs.
RECOM has introduced the term 3D Power Packaging® to describe techniques developed to create low-power DC/DC converters that function as true SMT components. These designs are classified as advanced ‘Power Packages’ or ‘Power Modules,’ offering capabilities that cannot realistically be replicated as discrete designs on a PCB, similar to how replacing a processor with a discrete design is impractical.
Techniques utilized in the 3D Power Packaging concept include integrated magnetics, control ICs embedded in multilayer substrates with buried and blind vias, flip-chip mounting of the IC and leadframe technology. SMD termination technologies include QFN, SSOP and LGA as well as traditional gull-wing.

Non-Isolated Power Modules
Non-isolated DC/DC converters share a common input and output ground connection and are used when galvanic separation is not necessary for safety or functional reasons. Voltage conversion can be achieved using a ‘linear regulator’, often with poor efficiency, or by the ‘buck’ or ‘boost’ switching regulator technique. In this arrangement, a semiconductor switch ‘chops’ the input voltage with variable duty cycle to achieve a lower average voltage while an inductor and capacitor network acts as a low pass filter to restore the waveform to DC. Without a transformer, the circuit can be remarkably simple and achieve exceptionally high efficiency, even with high input-output voltage ratios. In many cases, parts from RECOM can ‘drop in’ as replacement for linear regulators with a dramatic increase in efficiency, eliminating costly heatsinks and freeing-up valuable board space.
With RECOM 3D-Power Packaging technology, non-isolated DC/DC converters become ‘Power Modules’ with closely integrated semiconductors and magnetic components. DC/DC Converter modules of this style are called ‘switching regulators’ or sometimes ‘Point of Load ‘converters (PoLs) or VRMs (Voltage Regulator Modules).

RPX/RPY - Non isolated QFN Power Modules
The RPX series in an ultra-compact QFN package is widely used as a Point-of-Load regulator for loads requiring supply voltages down to 0.8V such as CPUs, GPUs, and SoC devices, with their exacting regulation and noise requirements. High efficiency is essential for maintaining cool operation in space and weight-sensitive applications, such as portable devices. In industrial applications, a wide input range offers valuable safety margins to accommodate transient conditions. Traditionally, low losses have been achieved by utilizing low switching frequencies. However, RECOM technology, along with advances in semiconductors and magnetic materials allow operation in the MHz region with good efficiency to allow micro-miniaturization.
The RPX series has a footprint of just 3mm x 5mm x 1.6mm for the 1A and 1.5A versions, 4.5mm x 4mm x 2mm for the 2.5A version and 5mm x 5.5mm x 4.1mm for the 4A variant which has a peak efficiency of over 90%. High power density is achieved with a low-cost flip-chip on leadframe and integrated-inductor construction with over-molding. This gives the added benefits of tight switching current loops generating exceptionally low EMI, along with high power density and optimized thermal performance, all in a QFN package. Astonishing ‘3D Power Packaging’ performance that cannot be matched by a discrete solution.

R-78AA-1.0 and ROF-78E high efficiency three terminal linear regulator replacements
Over many years, high-efficiency switching regulator replacements for the traditional ‘78xx series’ linear regulators have been released. Although ‘drop-in’ through-hole equivalent parts have been popular, surface-mount types are now preferred.
As one of the first manufacturers to make a switching regulator module, RECOM first addressed the market with an encapsulated gull-wing 1A-rated part, the R-78AA-1.0 series, which has a wide input range of up to 18V, allowing 5V, 9V, 12V, or 15V unregulated supplies to be used, and fixed regulated outputs of 1.5V,1.8V, 2.5V, or 3.3V, in a volume of just 1.75cm3. For applications where a low-profile open-frame product was preferred, the RECOM ROF-78E series offered a 0.5A rating with a wider input range of up to 36V and fixed output voltages of 3.3V, 5V, or 12V in a total volume of 0.68cm3.

Isolated DC/DC Converters
When safety agency certified isolation is required, besides voltage withstand, minimum creepage and clearance distances are defined. For example, in medical applications with mains system voltages, 8mm creepage is required between input and output for two Measures of Patient Protection (2MOPP). Given this minimum packaging dimension, a more traditional approach can be taken, with an internal die comprised of a power chiplet and control chiplet wire-bonded to a DVE SOIC-16 leadframe, then conventionally over-molded, such as in the RECOM RxxCT(E) and RxxC05TE parts. The transformer in these low power DC/DC converters is a proprietary, very low profile, planar-type design, achieving up to 5kVAC/1min isolation voltage and reinforced, 2MOPP isolation. The overall height of these parts is only 2.50-2.65mm, making them suitable for card-type applications as the height of the isolated DC/DC converter is not higher than the other typical surface mount components.
RS12-Z - 12W isolated and regulated DC/DC Converters SIP format
The RS12-Z series of DC/DC converters achieves class-leading power density in a SIP8 format by leveraging planar transformer technology with advanced packaging and thermal design. In a metal case, the series features high efficiency and operates at full 12W load to +75°C with convection cooling only (24V input). Pinout is industry standard with backwards-compatibility to 3W and 6W parts in the SIP8 format, for an easy power upgrade. Minimal external filtering is required to achieve EN 55032 EMC compliance, class A or B. The parts also include an output trim function and input under voltage lockout as well as continuous short circuit protection.
The parts are ideal when a wide input range is required, covering multiple nominal voltages.

R1SX, R2SX, R1DX, R1ZX - Surface-mount isolated DC/DC Converters
These low power DC/DC converters feature the unique RECOM ‘3D packaging technology’. A custom plastic molding supports the control PCB, which serves as the top surface of the module, while the isolation transformer is mounted underneath. This design minimizes the overall footprint, with module heights ranging from 5.8mm to 8.5mm, depending on the family. The open-frame construction has particular value when surface-mount reflow profiles are too severe for potted or molded parts. The R1SX series provides a single output at 1W up to +100°C while the R1DX provides dual outputs. Both parts are agency-certified with 3kV/1 second isolation. The R1ZX series is similar to the R1SX but includes a linear regulator for a precise, low noise output with 2kV/1 second isolation. The R2SX series provides 2W up to +75°C (+100°C with derating) and withstands 3kV/1 second.
All devices in this packaging format have industry standard and compatible pin-outs and are ideal for use in bus isolators, industrial controls, and battery management systems.
