MIC24045 I2C Programmable, 4.5V - 19V Input,5A Step-Down Converter
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 theMIC24045 various parameters can be programmed viaI2C, 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.
The MIC24045 supports extensive diagnostics and status information through I²C.
The MIC24045 pinout is compatible with the MIC24046pin-strapping programmable regulator pinout, such thatI2C-based implementations can be easily converted into pin-programmable ones.
The MIC24045 is available in a thermally efficient,space-saving 20-pin 3 mm x 3 mm FQFN package,with an operating junction temperature range from –40°C to +125°C.
