Semtech SC4524C

28V 2A Step-Down Switching Regulator

The SC4524C is a constant frequency peak current-mode step-down switching regulator capable of producing 2A output current from an input ranging from 3V to 28V. The switching frequency of the SC4524C is programmable up to 2MHz, allowing the use of small inductors and ceramic capacitors for miniaturization, and high input/output conversion ratio. The SC4524C is suitable for next generation XDSL modems, high-definition TVs and various point of load applications.
