AT1382B

www.DataSheet4U.com AT1382B Preliminary Product Information 4-Channel DC-DC Converter for DSC Features Low start-up power supply voltage :1.4V(CH4) Wide supply voltage range from 1.8V to 7V (CH1~4) High speed operation is possible: Maximum 1 MHz Supports for down and up/down Zeta conversion (CH1) Supports for up, flyback and up/down SEPIC conversion (CH2,3,4) Totem-pole type output for MOSFET Built-in On/Off function Built-in Short-Circuit Protection 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/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. 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.
