Abstract
A power supply may comprise a pulse-width-modulation (PWM) controller; a synchronous rectifier having a forward metal oxide field effect transistor (MOSFET) and a catch MOSFET; a forward gate driver; a catch gate driver; and the PWM controller connected so that a low output of the PWM controller facilitates operation of the catch MOSFET and so that the low output precludes operation of the forward MOSFET. The power supply may include a self powered synchronous rectifier that may be constructed with delay times that are independent of lot-to-lot and temperature-related timing variations of MOSFETS.
