AT1386 Overview
The AT1386 is a 6-channel PWM DC/DC control IC for low voltage applications with a soft start function and short circuit detection function. This IC is ideal for up conversion, down conversion, and up/down conversion (using a step-up/stepdown SEPIC system with free input and output settings). 6 channels can be built in the LQFP48 package, each channel be controlled, and soft-start.
