85V STARTUP, 1MHZ, 300mA IOUT SYNCHRONUS BOOST STEP-UP DC-DC CONVERTER
A7533
DESCRIPTION
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.
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.
The A7533 is available in SOT-25 and SOT-89-3 Package.
