* This document contains certain information on a new product.

Specifications and information herein are subject to change without notice.

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.

Features

•45 mΩ Integrated N-Channel Power MOSFETs

• Input Voltage Operating Range from 3.0 V to 6.0 V

•

±1 % Accurate Output Voltage, Ranging from 0.7 V to 3.6 V

• Voltage Tracking Capability in different configurations.

• Programmable Switching Frequency Range from 200 kHz to

1.0 MHz with a default of 1.0 MHz

• Programmable Soft Start Timing

• Over Current Limit and Short Circuit Protection

• Thermal Shutdown

• Output Overvoltage and Undervoltage Detection

• Active Low Power Good Output Signal

• Active Low Shutdown Input

• Pb-Free Packaging Designated by Suffix Code EP.
