AT1386

• 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 (CH 1,2,3,4,5,6)
• 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.

The AT1386 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 AT1386 is ideal for up conversion, down conversion, and up/down conversion (using a step-up/stepdown SEPIC system with free input and output settings). 6 channels can be built in the LQFP48 package, each channel be controlled, and soft-start.

The AT1386 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.)
