4MHz monolithic synchronous step-down regulators bring high efficiency to space-sensitive applications
Joey M. Esteves
Abstract
The LTC3411 and LTC3412, high performance monolithic, synchronous step-down DC/DC converters that are well suited for applications requiring up to 1.25A and 2.5A of output current, respectively, are described.

Introduction
The LTC3411 and LTC3412 provide compact and efficient power supply solutions for portable electronics such as cell phones, PDAs and notebook computers. These two monolithic, synchronous step-down regulators provide DC/DC conversion from either a 3.3V or 5V system voltage to outputs as low as 0.8V. They also offer switching frequencies ...
