General Description
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/step-
down SEPIC system with free input and output
settings). 6 channels can be built in the LQFP48
package, each channel be controlled, and soft-start.
The AT1386 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.)
