Description

The SC4201 is a multi-phase link controller, ideal for isolated and non-isolated applications. Its frequency of operation can be programmed in excess of 2MHz per phase (oscillator frequency = phase frequency times number of phases 3 or 4) and can be easily synchronized to an external faster frequency. The SC4201 output frequencies can be set to 2/4 or 3 phase operation. A single pin can either set a 4 phase operation (each phase is 90 degrees apart) or 3 phase operation (120 degrees apart).

Features
