AT1388A

www.DataSheet4U.com AT1388/AT1388A Preliminary Product Information 6-Channel DC-DC Controller 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 (AT1388:CH2,3,4,5,6 AT1388A:CH2,3,4,6) Supports for down and up/down Zeta conversion (AT1388:CH1 AT1388A:CH1,CH5 ) Synchronized rectification on CH1,CH2 Supports for inverting converter CH5 Built-in On/Off function Built-in Soft-Start Function Built-in Short-Circuit Protection. General Description The AT1388/AT1388A 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 stepup/step-down 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 AT1388 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.)
