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. DataSheet4U. com
