ACE710C

1A Synchronous PWM Boost converter

VER 1.1

1

Description

The ACE710C is a step-up converter that provides a boosted output voltage from a low voltage source.

Because of its proprietary design, it starts up at a very low input voltage down to 0.9V, and only consumes

15uA at standby, making it an ideal choice for single cell alkaline/NiMH battery operations.

A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile

inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing

external parts count.

ACE710C is available in SOT23-5 Package.

Features

 Efficiency up to 95%@Vin=4.0V, Vout=5.0V

 Typical 15uA standby current

 1MHz Switching Frequency allows small inductor and output cap

 Input boost-strapping allows using small or no input cap

 Low Vin Start-up Voltage down to 0.9V Ideal for Single Alkaline Cell operations

 Maximum Output Current up to 1A

 Low Noise PWM control

 Internally Compensated Current Mode Control

 Internal Synchronous Rectifier

 Logic Control Shutdown (IQ<1uA)

 Available in SOT23-5

Applications

 One to Three Cell Battery Operated Devices

 Medical Instruments

 Bluetooth Headsets

 Flash-Based MP3 Players

 Noise Canceling Headphones
