High power 3-phase auxiliary power supply design based on L5991 and ESBT STC08DE150
This application note deals with the design of a 3- Phase auxiliary power supply for 150W dual output SMPS, using the L5991 PWM driver and the STC08DE150 ESBT as main switch. The combination of these ST's parts aims at obtaining a high efficiency solution for high DC input voltage, typical requirement of any three phase application. The L5991 driver is an upgraded version of the UC384X current mode PWM driver. It boasts some very interesting additional features.
