概览
The SC4524D is a constant frequency peak current-mode step-down switching regulator capable of producing 2A output current from an input ranging from 3V to 18V. The switching frequency of the SC4524D is programmable up to 2MHz, allowing the use of small inductors and ceramic capacitors for miniaturization, and high input/output conversion ratio.
