LTC1538-AUX
The drive for higher performance portable electronic systems, concomitant with the need to remain compatible with existing interfacing standards and hardware, has caused the number of system power supply voltages to proliferate. This Design Note describes how to generate five separate output voltages using the LTC1538-AUX, a dual synchronous switching regulator controller with internal circuitry adaptable to many additional configurations. The five output voltages ...
