HIGHEST POWER DENSITY IN ITS CLASS
The RPX-4.0 step-down switching regulator provides 4A output current at voltages between 1V and 7V, programmable by external resistors. Input range is 3.8V to 36V covering nominal 5V, 12V and 24V for a wide range of applications. Size is just 5.0 x 5.5mm footprint and 4.1mm height in a thermally-enhanced QFN package. Full protection is provided against short-circuits, output overcurrent and over-temperature.
The RPX-4.0 efficiency is high, allowing full power operation up to 65°C and derated operation up to 90°C. Construction follows the RECOM ‘3D Power Packaging®’ technology for high power density, with flip-chip on leadframe construction, an integrated shielded inductor for low EMI, and intelligent control of switching frequency to maintain high efficiency even at light load. An evaluation board, RPX-4.0-EVM-1, is also available, allowing customers to exercise all of the product features and optimize filtering to meet target system requirements.

Industry
Industrial applications have long been RECOM’s core strength with a vast range of rugged single- and three-phase AC/DC power supplies, along with isolated DC/DC converters and non-isolated switching regulators. Operating temperatures are wide and efficiencies are high for reliable solutions at an attractive cost.
Medical
AC/DC and DC/DC converters for medical applications have to meet enhanced specifications for operator and patient safety. RECOM’s range of medical products are fully certified up to 2MOOPs and have low leakage current ratings for the most sensitive patient-connect applications as well as for home healthcare and lab environments.

Mobility
Railway applications, EVs, disability scooters and many small vehicles need on- and off-board power converters for powering electronic equipment and battery charging. The environment is often harsh but RECOM DC/DC and AC/DC converters are perfect for the application, with a wide range of high-specification standard parts and the possibility of custom designs from RECOM sister company PCS.
Test & Measurement
T&M is a wide application area and RECOM products can be found throughout. Products provide AC/DC conversion and auxiliary DC/DC conversion for generation of local supply rails, to provide ground isolation for sensitive measurement circuitry and for communication bus power isolation.
Automation
Automation in industry, in the home and the Internet of Things (IoT) are well served by RECOM products with a range of high and low-power power converters matching the requirements for high efficiency, low standby current, small size and cost effective.
Cost Effective
Low unit and lifetime cost are priorities for RECOM, with the benefits of production in low-cost areas and economy of scale passed on customers. High, proven reliability of RECOM products also ensures ‘fit-and-forget’ integration into customers products for low lifetime cost.
High Power Density
Modern electronics demands more power in less volume and RECOM is pioneering high power density advances in its ‘3D Power Packaging’ program. Full-function switching regulators and isolated DC/DC converters are now available in micro-miniature formats using a variety of advanced packaging techniques and circuit designs.
Gate Drivers
The simplest (functional) isolation of a DC/DC converter can withstand 1kVDC for one second, however this is often not sufficient for high-side gate drivers. RECOM combines the required high insulation voltage, asymmetric output voltages, and low isolation capacitance into one simple DC/DC module.
