Single IC, 5 Output Switching Power Supply


Posted on Mar 28, 2013

This Design Note describes how to generate five separate output voltages using the LTC®1538-AUX, a dual synchronous switching regulator controller with internal circuitry adaptable to many additional configurations.



The 5V and 3.3V switching regulators, independently activated by the two RUN/SS pins, provide very efficient, constant frequency operation. This is accomplished by using a synchronous-buck architecture at high currents and switching over to Burst Mode
