Technology

300mA Iout, 0.85V startup, 1MHz, Synchronous Boost Converter

VER 1.2

Description

The ACE708 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 850mV, 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.

Features

• Up to 95% Efficiency

• 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 850mV Ideal for Single Alkaline Cell operations

• Maximum Output Current up to 300mA

• Low Noise PWM control

• Internally Compensated Current Mode Control

• Internal Synchronous Rectifier

• Logic Control Shutdown (IQ<1uA)

• Available in SOT-23-5

Application

• One to Three Cell Battery Operated Devices

• Medical Instruments

• Bluetooth Headsets

• Flash-Based MP3 Players

• Noise Canceling Headphones
