    XC9301/9302 Series
    PWM, PWM/PFM Switching
    Step-Up & Down DC/DC Controller
    General Description
    Features
    The XC 9301/02 series are step-up/down DC /DC converter
    controller IC s with fast, low ON resistance drivers built-in. A
    versatile, large output current, step-up/down DC /DC con-
    verter can be realised using only 4 basic external components
    - transistors, coils, diodes and capacitors.
    Output voltage is selectable in 0.1V steps within a 2.4V ~ 6.0V
    ( ± 2.5% accuracy) range and switching frequency is set at
    180kHz.
    The XC 9302 series switches from PWM to PFM control during
    light loads and the series offers high efficiencies from light
    loads through to large output currents.
    Soft-start time is internally set to 10 msec which offers pro-
    tection against rush currents when the power is switched on
    and also against voltage overshoot.
    During shutdown (C E pin = L), consumption current can be
    reduced to as little as 0.5
    μ
    A or less.
    Input Voltage Range:
    2.0V ~ 10V
    Output Voltage Range:
    2.4V ~ 6.0V ( ± 2.5% accuracy)
    (selectable in 0.1V steps)
    Oscillation Frequency:
    180KHz ( ± 15% accuracy)
    Output Current:
    more than 250mA (V
