This Design Note describes how to generate five separateoutput voltages using the LTC®1538-AUX, a dual synchronousswitching regulator controller with internal circuitryadaptable to many additional configurations. visit page.
The 5V and 3.3V switching regulators, independently activatedby the two RUN/SS pins, provide very efficient,constant frequency operation. This is accomplished byusing a synchronous-buck architecture at high currentsand switching over to Burst Mode visit page.
