com AT1382A 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 up, flyback and up/down SEPIC conversion (CH1~4) • Totem-pole type output for MOSFET • Built-in On/Off function • Built-in Short-Circuit Protection.
General Description The AT1382A 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 SEPIC system with free input and output settings).
Four channels can be built in the LQFP48 package, each channel be controlled, and soft-start.
The AT1382A 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.
Applications • Digital Cameras • CCD Imaging Devices • Camcorders Pin Assignment Ordering Information Part number AT1382AF AT1382AF_PBF AT1382AF_GRE Package LQFP48 LQFP48, PB-Free LQFP48,Green Marking AT1382AF AT1382AF,date code with one bottom line AT1382AF,date code with two bottom line Aimtron reserves the right without notice to change this circuitry and specifications.
