3A 750KHz Asynchronous Boost Converter



GENERAL DESCRIPTION

The MA2004A is a current mode step up converter, fixed frequency, inrush current limiting

and internal soft-start. It includes an error amplifier, ramp generator, comparator, built-in 70mΩ

N-Channel power MOSFET make this regulator highly power efficient.

The 750KHz switching frequency allows for smaller external components producing a

compact solution for a wide range of load currents. The MA2004A regulates the output voltage

up to 5.5V and provides up to 1A output.
