GENERAL DESCRIPTION
The AIC1340 combines a synchronous voltage mode PWM controller with a low dropout linear regulator and a linear controller as well as the monitoring and protection functions in this chip. The PWM controller regulates the output voltage with a synchronous rectified step-down converter. The built-in N-Channel MOSFET drivers also help to simplify the design of step-down converter. It is able to power CPUs, GPUs, memories, and chipsets. 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.
