SC4525E
Not Recommended for New Designs
The SC4525E is a constant frequency peak current-mode step-down switching regulator capable of producing 3A output current from an input ranging from 3V to 28V. The switching frequency of the SC4525E is programmable up to 2MHz, allowing the use of small inductors and ceramic capacitors for miniaturization, and high input/output conversion ratio. The SC4525E is suitable for next generation XDSL modems, high-definition TVs and various point of load applications.
