AiT Semiconductor Inc.

DC-DC CONVERTER/BOOST(STEP-UP)

0.9V STARTUP, 1MHZ, 300MA IOUT, LOW IQ, SYNCHRONOUS

BOOST CONVERTER

DESCRIPTION

FEATURES

The A7534 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.



Efficiency up to 94%@V_IN=3.3V, V_OUT=5.5V

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

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.



Maximum Output Current up to 300mA

Low Noise PWM control

Internally Compensated Current Mode Control

Internal Synchronous Rectifier

Available in SOT-23 and SOT89-3 Packages

The A7534 is available in SOT-23 and SOT89-3

packages.
