Product Summary

SC4525ASETRT is a constant frequency peak current-mode step-down switching regulator capable of producing 3A output current from an input ranging from 8V to 28V. The switching frequency of the SC4525ASETRT is programmable up to 2MHz, allowing the use of small inductors and ceramic capacitors for miniaturization, and high input/output conversion ratio. Applications of the SC4525ASETRT include: XDSL and Cable Modems, Set Top Boxes, Point of Load Applications, CPE Equipment, DSP Power Supplies and LCD and Plasma TVs.
