    Low-Noise, Step-Up DC-DC Converter
    ____________________________Features The MAX1703 is a high-efficiency, low-noise, step-up
    DC-DC converter intended for use in battery-powered
    wireless applications. It uses a synchronous-rectified
    pulse-width-modulation (PWM) boost topology to generate a 2.5V to 5.5V output from battery inputs, such as
    one to three NiCd/NiMH cells or one Li-Ion cell. The
    device includes a 2A, 75mΩ, N-channel MOSFET
    switch and a 140mΩ, P-channel synchronous rectifier.
    With its internal synchronous rectifier, the MAX1703
    delivers up to 5% better efficiency than similar nonsynchronous converters. It also features a pulse-frequencymodulation (PFM) low-power mode to improve efficiency
    at light loads, and a 1µA shutdown mode.
    The MAX1703 comes in a 16-pin narrow SO package ...
