GENERAL DESCRIPTION

The AIC1341 combines a synchronous voltage mode PWM controller with two linear controllers as well as the monitoring and protection functions in this chip. The PWM controller regulates the output voltage with a synchronous rectified stepdown converter. The built-in N-Channel MOSFET drivers also help to simplify the design of stepdown converter. It is able to power CPUs, GPUs, memories, chipsets and multi-voltage applications. The PWM controller features over current protection using RDS(ON). It improves efficiency and saves cost, as there is no expensive current sense resistor required.
