Microchip Technology MIC24045
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. 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.| Part No. | MIC24045 |
