Description

This application note is intended to assist designers in the transition from Semtechs SC4525A and SC4525B step-down switching regulators to the SC4525C and SC4525D devices. The SC4525C and SC4525D regulators share the identical. Nov 8, 2007 The SC4525A 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 SC4525A is programmable. SC4525A . SC4524A, SC4525A . SC2545, SC2442H. SC2463, SC4612. Power Management Selection Tables. Altera FPGA I/O Voltage.
