The A7501E3R-27 from AiT Semiconductor is a Boost DC-DC Converter that converts an input voltage from -0.3 V to +6.5 V to an output voltage of 1.8-5 V. It has an efficiency of up to 88%. This converter is designed to consume ultra-low supply current and is manufactured using CMOS technology, making it ideal for battery-powered devices. It features an oscillator, VFM control circuit, driver transistor (LX switch), reference voltage unit, error amplifier, voltage-detection resistors, and an LX switch protection circuit.

This converter has a built-in protection mechanism that offers safety by shutting off the internal MOSFET if the voltage at the CONT pin exceeds safe levels. This RoHS-compliant boost converter is available in a surface-mount package that measures 4.600 x 4.250 mm and is ideal for cameras, camcorders, PDAs, pagers, handheld communication devices, and audio equipment applications.
