SC2677
Product inactive. Information on this page is for reference only.
The SC2677 is a versatile 2 phase, synchronous, voltage mode PWM controller that may be used in two distinct ways. First, the SC2677 is ideal for applications where point of use output power exceeds any single input power budget. Alternatively, the SC2677 can be used as a dual switcher. The SC2677 features a temperature compensated voltage reference, an under voltage lockout over current protection and internal level-shifted, high-side drive circuitry.
