SC2440 Datasheet 2.5 Mhz Dual Switching Regulator

Manufacturer: SEMTECH

Overview: 2.5 MHz Dual Switching Regulator with Integrated 2A Switches www.DataSheet4U.

General Description

The SC2440 is an adjustable frequency dual currentmode switching regulator with 2A integrated switches.

Its high frequency operation allows the use of small inductors and capacitors, resulting in very compact power supplies.

The SC2440 is suitable for next generation XDSL modems requiring operating frequencies in excess of 1.5 MHz.
