产品概述
The MIC24045-2ZYFL-TR is an I2C programmable, 4.5V to 19V input, 5A step-down converter in 20 pin FQFN package. It is perfectly suited for multiple voltage rail application environments typically found in computing & telecommunication systems. In MIC24045 various parameters can be programmed via I2C such as output voltage, switching frequency, soft-start slope, margining, current limit values & start-up delays. The wide switching frequency adjustment range, valley current mode control technique, high performance error amplifier and external compensation allow for best trade-offs between high efficiency and smallest possible solution size. The MIC24045 supports extensive diagnostics and status information through I2C. It is pin-out is compatible with MIC24046 pin-strapping programmable regulator pin-out such that I2C based implementations can be easily converted in to pin programmable ones. It is used in servers, data storage, routers, base stations, FPGAs, DSP & low voltage
