SC1175
Product is not recommended for new design.
The SC1175 is a versatile 2 phase, synchronous, voltage mode PWM controller that may be used in two distinct ways. First, the SC1175 is ideal for applications where point of use output power exceeds any single input power budget. Alternatively, the SC1175 can be used as a dual switcher.
