Product details

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. www. DataSheet4U. com SC411 Features Constant on-time for fast dynamic response Programmable VOUT range = 0.5.
VCCA VBAT range = 1.8V.
25V DC current sense using low-side RDS(ON) Sensing or sense resistor Resistor programmable frequency Cycle-by-cycle current l.
