SC4201(2004) Datasheet PDF - Semtech Corporation

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
♦ Small footprint MSOP-8
♦ Programmable frequency > 2MHz, each phase
♦ Synchronized to faster frequency
♦ Programmable 2/4 or 3 phase operation

APPLICATIONs
♦ Telecom distributed power architectures
♦ Multi-phase operation of isolated power supplies
♦ Multi-phase operation of non-isolated switching regulators
