SC4524C数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

Not Recommended for New Designs, Recommended Replacement Part is SC4524ESETRT
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.
