    I2C Programmable, 4.5V-19V Input,
    5A Step-Down Converter
    Features General Description The MIC24045 is an I2C-programmable, high-efficiency, wide input range, 5A synchronous step-down
    regulator. The MIC24045 is perfectly suited for multiple
    voltage rail application environments, typically found in
    computing and telecommunication systems. In the
    MIC24045 various parameters can be programmed via
    I2C, such as output voltage, switching frequency,
    soft-start slope, margining, current limit values and
    start-up delays. The wide switching frequency
    adjustment range, valley current-mode control technique, high-performance error amplifier and external
    compensation allow for the best trade-offs between
    high efficiency and the smallest possible solution size. 4.5V to 19V Input Voltage Range
