RECOM Power RVS002 Micropower Isolated Power Bridge Rectifier

RECOM Power RVS002 Micropower Isolated Power Bridge Rectifier is a compact bridge rectifier chip specifically designed for micro-power isolated power supply applications in space-constrained environments. When used with a transformer driver and transformer, the RECOM Power RVS002 requires only simple output filter capacitors to form a complete isolated power supply system. This power supply system features an output voltage range of 2V to 6V and output power between 1W and 3W. RVS002 integrates two N-channel power MOSFETs and two Schottky diodes, forming a full bridge rectifier. Using only a single winding on the transformer’s secondary side, the RVS002 design significantly simplifies transformer design, reducing size and lowering cost. An integrated intelligent voltage limiter prevents the output voltage from rising excessively under no-load conditions, ensuring voltage stability. When the power supply is under load, the limiter remains inactive and draws no current, thereby maintaining high efficiency at full load.
