SC411 - Synchronous Buck Pseudo-Fixed Frequency Power Supply Controller

SC411 Description

Synchronous Buck Pseudo-Fixed Frequency Power Supply Controller POWER MANAGEMENT .
The SC411 is a constant on-time synchronous buck PWM controller in a space-saving MLPQ package intended for use in notebook computers and other batter.

SC411 Features

* include high efficiency and a fast dynamic response with no minimum on-time. The excellent transient response means that SC411 based solutions will require less output capacitance than competing fixed frequency converters. www.
