摘要:
A no load detection and shutdown circuit (20) in an isolated driver (10) is provided. A no load condition is detected by primary side evaluation of a reflected voltage. If a determination is made that a no load condition is present, the no load detection circuit (20) signals a half bridge inverter (16) of the driver (10) to cease oscillations, shutting down the driver (10).
