The AT1387A 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 AT1387A is ideal for up conversion, down conversion,and up/down conversion (using a step-up/stepdown SEPIC ,Zeta system with free input and output settings). 6 channels can be built in the LQFP48 package, each channel be controlled, and soft-start.
The AT1387A include one comparator to generate low-battery warning outputs. It also contains two high efficiency topology by using synchronous rectification PWM(It can be disable by floating OUT1_2,OUT2_2.)
