com AT1387A Preliminary Product Information 6-Channel DC-DC Converter for DSC Features • Low start-up power supply voltage :1.
4V(CH6) • Wide supply voltage range from 2.
5V to 6.
5V (CH1~6) • High speed operation is possible: Maximum 1 MHz • Supports for up, flyback and up/down SEPIC conversion (CH3,4,5,6) • Supports for down and up/down Zeta conversion (CH1,2) • Synchronized rectification on CH1,CH2 • Supports for negative voltage feedback CH5 • Built-in On/Off function • Built-in Soft-Start Function • Built-in Short-Circuit Protection.
General Description The AT1387A 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/stepdown SEPIC ,Zeta system with free input and output settings).
6 channels can be built in the LQFP48 package, each channel be controlled, and soft-start.
The AT1387A 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.
) Applications • Digital Cameras • CCD Imaging Devices • Camcorders Pin Assignment Ordering Information Part number AT1387AF AT1387AF_PBF AT1387AF_GRE Package LQFP48 LQFP48, PB-Free LQFP48, Green Marking AT1387AF AT1387AF, date code with one bottom line AT1387AF, date code with two bottom line Aimtron reserves the right without notice to change this circuitry and specifications.
