Point of Load DC/DCs with High-Efficiency Suit Distributed Power
Dec 15, 2022
Two new ranges of cost-effective switching regulators are announced - the RPMGQ-20 and RPMGS-20 open-frame, through-hole, non-isolated DC/DC buck converters with 20A output rating.
The RPMGQ-20 is in an industry-standard quarter-brick format while the RPMGS-20 is in the emerging standard package size of 36.83 x 34.04mm with a standard sixteenth brick pin-out. Both products have a maximum height of 15mm from their mounting surface. The parts operate from an 18V-75V input and optional nominal outputs are 5V or 12V, trimmable over a wide range, 3.3V to 8V and 8V to 24V respectively.
The efficiency of the RPMGQ-20 and RPMGS-20 parts is very high, peaking at 98% for the 12V output versions and 94% for 5V output, with a nearly-flat efficiency curve down to around 10% load. Due to the low losses and advanced thermal design, full load is available with air-flow to an ambient temperature of more than 90°C for all variants with derating to 120°C.
The products feature comprehensive protection against input undervoltage, output over-current, short circuits, and over-temperature. Remote sense and control input is also provided.
