Dual High-efficiency PWM Step-down DC-DC Converter with OVP

AUR9707

Features

General Description

•

Dual Channel High Efficiency Buck Power

Converter

Low Quiescent Current

The AUR9707 is a high efficiency step-down

DC-DC voltage converter. The chip operation is

optimized using constant frequency, peak-current

mode architecture with built-in synchronous power

MOSFET switchers and internal compensators to

reduce external part counts. It is automatically

switching between the normal PWM mode and LDO

mode to offer improved system power efficiency

covering a wide range of loading conditions.

•

Output Current: 1A

Adjustable Output Voltage from 1V to 3.3V

Wide Operating Voltage Range: 2.5V to 5.5V

Built-in Power Switches for Synchronous

Rectification with High Efficiency

Feedback Voltage: 600mV

1.5MHz Constant Frequency Operation

Automatic PWM/LDO Mode Switching Control

Thermal Shutdown Protection

•

The oscillator and timing capacitors are all built-in

providing an internal switching frequency of 1.5MHz

that allows the use of small surface mount inductors

and capacitors for portable product implementations.

Additional features included Soft Start (SS), Under

Voltage Lock Out (UVLO), Input Over Voltage

Protection (IOVP) and Thermal Shutdown Detection

(TSD) are integrated to provide reliable product

applications.

Low Drop-out Operation at 100% Duty Cycle

No Schottky Diode Required

Internal Input Over Voltage Protection

Applications

•

Mobile Phone, Digital Camera and MP3 Player

Headset, Radio and Other Hand-held Instrument

Post DC-DC Voltage Regulation

The device is available in adjustable output voltage

versions ranging from 1V to 3.3V, and is able to

deliver up to 1A.

PDA and Notebook Computer

The AUR9707 is available in WDFN-3×3-12

package.
