MIC24046YFL-TR is a pin-programmable, high-efficiency, wide-input range, 5A, synchronous step-down regulator. The MIC24046YFL-TR is perfectly suited for multiple-voltage rail application environments typically found in computing and telecommunication systems. It can be programmed by pin strapping various parameters, such as output voltage, switching frequency, and current-limit values. The pin-selectable switching frequency, valley-current-mode control technique, high-performance error amplifier, and external compensation allow for the best tradeoffs between high-efficiency and the smallest possible solution size.
The MIC24046YFL-TR is pin-out compatible with its I2C-programmable counterparts from the same family. The MIC24046YFL-TR is available in a thermally-efficient, space-saving, 20-pin 3mm x 3mm QFN package with an operating junction temperature range of -40°C to +125°C.
