A7533 Description
AiT Semiconductor Inc.www.ait-ic.com 0.85V STARTUP, 1MHZ, 300mA IOUT SYNCHRONUS BOOST STEP-UP DC-DC CONVERTER A7533 .
The A7533 is a step-up converter that provides a boosted output voltage from a low voltage source.
A7533 Features
* Up to 95% Efficiency Output voltage accuracy ±3% 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
* Max
A7533 Applications
* that only need to drive small output load current, the input capacitor is optional, because once output is started up, the IC's is powered by OUT, a quiet power supply. The output capacitor is used to stabilize the loop and provide ac current to the load. A low ESR ceramic cap with values from 2.2uF
