MA2004-3A 700KHz Asynchronous Boost Converter


MA2004-3A 700KHz Asynchronous Boost Converter DataSheet

GENERAL DESCRIPTION
    The MA2004 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 150mΩ N-Channel power MOSFET make this regulator highly power efficient. The 700KHz switching frequency allows for smaller external components producing a compact solution for a wide range of load currents. The   MA2004 regulates the output voltage up to 5.5V and provides up to 1A output.
