Effektive DC/DC-konvertere til distribuerede power-systemer
RECOM lancerer nye 'point-of-load' ikke-isolerede DC/DC buck konvertere, der er særdeles velegnede til brug i distribuerede power-systemer (in english).
Two new ranges of cost-effective switching regulators are now available from RECOM - the RPMGQ-20 and RPMGS-20. Both are open-frame, through-hole, non-isolated DC/DC buck converters with an 18V-75V input. Optional nominal outputs are 5V or 12V trimmable over a wide range, 3.3V to 8V and 8V to 24V respectively.
- These super-high efficiency DC/DCs with their high operating temperature capability are ideal as a point of load converters in demanding distributed power architectures, explains Matthew Dauterive DC/DC product manager of RECOM.
Output current for all variants is 20A and 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 efficiency of both variants 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. Remote sense and control input is provided and the products feature comprehensive protection against input undervoltage, output over-current, short circuits, and over-temperature.
With air-flow, full load is available to an ambient temperature of more than 90°C for all variants with derating to 120°C.
Samples and OEM pricing of the RPMGQ-20 and RPMGS-20 ranges are available from all authorized distributors or directly from RECOM.
