DS20005568A-page 1 MIC24045 Features • 4.5V to 19V Input Voltage Range • 5A (maximum) Output Current •I2C Programmable Output Voltage: - 0.64V to 5.25V in 5 mV, 10 mV, 30 mV and 50 mV steps • High Efficiency (>95%) •I2C Programmability of: - Soft-Start: 0.16, 0.38, 0.76 and 1.5V/ms ramp rates - Switching Frequency: 310 kHz, 400 kHz, 500 kHz, 570 kHz, 660 kHz, 780 kHz, 1 MHz, 1.2 MHz - Current Limits for 2A, 3A, 4A and 5A loads - Output Voltage Margining: -5%, +5% - Start-up delays: 0 ms to 10 ms • ±1% Output Voltage Accuracy Over Temperature (0.64V to 1.95V) • Supports Safe Start-Up with Pre-Biased Output • Extensive Diagnostics through I2C Interface Applications • Servers, Data Storage, Routers and Base Stations • FPGAs, DSP and Low-Voltage ASIC Power General Description The MIC24045 is an I2C-programmable, high-effi- ciency, 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 tech- nique, 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 MIC24046 pin-strapping programmable regulator pinout, such that I2C-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.
