General Description

The AT1395 is a 5-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,

inverting conversion (CH4 only) and up/down

conversion (using a step-up/step-down SEPIC or

Zeta system with free input and output settings). 5

channels can be built in the LQFP48 package, each

channel be controlled, and soft-start.

The AT1395 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.)
