SC1176 Datasheet PDF - Semtech Corporation

Description
The SC1176 is a versatile 2 phase, synchronous, voltage mode PWM controller that may be used in two distinct ways. First, the SC1176 is ideal for applications where point of use output power exceeds any single input power budget. Alternatively, the SC1176 can be used as a dual switcher. The SC1176 features a temperature compensated voltage reference, over current protection with 50% fold-back and internal level-shifted, high-side drive circuitry.
