Product details

Description

The SC1470 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 SC1470 based solutions will require less output capacitance than competing fixed frequency converters. SC1470 Features Constant on-time for fast dynamic response Programmable VOUT range = 0.5.
VCCA VIN range = 1.8V.
25V DC current sense using low-side RDS(ON) Sensing or RSENSE in source of low-side MOSFET for greater accuracy Resistor programmable fre.
