DC-DC CONVERTER BOOST(STEP-UP)

LOW VOLTAGE STARTUP, 1MHz, 500mA SYNCHRONOUS

DESCRIPTION

FEATURES



Low Vin Start-up Voltage down to 850mV

Ideal for Single Alkaline Cell operations

Capable of delivering 500mA output current at

Vin=3.0V, V out=3.3V

The A7533 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.

1MHz Switching Frequency allows small

inductor and output cap

Input boost-strapping allows using small or no

input cap

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.



Low Noise PWM control

Internally Compensated Current Mode Control

Internal Synchronous Rectifier

Logic Control Shutdown (I_Q<1uA)

Available in SOT-25 Package.

The A7533 is available in SOT-25 Package.
