The SC2677BTETRT is a versatile 2 phase, synchronous, voltage mode PWM controller that may be used in two distinct ways. First, the SC2677BTETRT is ideal for applications where point of use output power exceeds any single input power budget. Alternatively, the SC2677BTETRT can be used as a dual switcher. The SC2677BTETRT features a temperature compensated voltage reference, an under voltage lockout over current protection and internal level-shifted, high-side drive circuitry.
