AT1382B 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/stepdown 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.
AT1382B Key Features
