AT1387A
Preliminary Product Information
6-Channel DC-DC Converter for DSC
Features
General Description
• 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
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,
