Product details

Description

The SC470 is a single output, constant on-time synchronous-buck, pseudo-fixed frequency, PWM controller intended for use in notebook computers and other battery operated portable devices.

Features

include high efficiency and fast dynamic response with no minimum on-time. The excellent transient response means that SC470 based solutions will require less output capacitance than competing fixed frequency converters. www. DataSheet4U. com SC470 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 RSENSE in source of low-side MOSFET for greater accuracy Resist.
