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
