A7533 - AiT

A7533 DC-DC CONVERTER BOOST

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 p.
