Abstract:
A no load detection and shutdown circuit in an isolated driver 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 signals a half bridge driver of the driver to cease oscillations, shutting down the driver.
