Status: In Production
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. The MIC24045 supports extensive diagnostics and status information through I2C.The MIC24045 pin-out is compatible with the MIC24046 pin-strapping programmable regulator pin-out, such that I2C-based implementations can be easily converted into pin-programmable ones. The MIC24045 is available in 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.
The MIC24045 Evaluation Board is designed to serve the MIC24045 device. For the evaluation of the MIC24045 the VIN supply ranges from 4.5V to 19V and output voltage from 0.64V to 5.25V in 5mV, 10mV, 30mV and 50mV steps at 5A. Additionally, and on-board load transient generator circuit and connections for loop gain measurements are provided. A USB connector and a USB cable are provided for board...
