General Description
The AT1382B is a 4-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 Zeta(CH1) and SEPIC(CH2,3,4) system with
free input and output settings). Four channels can
be built in the LQFP48 package, each channel be
controlled, and soft-start.
The AT1382B include one comparator to generate
low-battery warning outputs. It also contains a gain
block that can be used with an external P-channel
MOSFET to make a low-dropout linear regulator.
