MIC24045 Overview
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 puting and telemunication 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...
