Overview

Synchronous Buck Pseudo-Fixed Frequency Power Supply Controller POWER MANAGEMENT Description 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 battery operated portable devices.
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.
