34713 Overview

5.0燗 1.0燤Hz fully integrated single switch-mode power supply

Freescale Semiconductor
Advance Information
Document Number: MC34713
Rev. 4.0, 5/2007
5.0 A 1.0 MHz Fully Integrated
Single Switch-Mode Power
Supply
The 34713 is a highly integrated, space efficient, low cost, single
synchronous buck switching regulator with integrated N-channel
power MOSFETs. It is a high performance point-of-load (PoL) power
supply with the ability to track an external reference voltage in
different configurations.
Its high efficient 5.0 A continuous output current capability
combined with its voltage tracking/sequencing ability and tight output
regulation, makes it ideal as a single power supply.
The 34713 offers the designer the flexibility of many control,
supervisory, and protection functions to allow for easy implementation
of complex designs. It is housed in a Pb-Free, thermally enhanced,
and space-efficient 24-Pin Exposed Pad QFN.
