Device Overview

Summary

MIC24046 is a pin-programmable, high-efficiency, wide-input range, 5A, synchronous step-down regulator. The MIC24046 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 MIC24046 is pin-out compatible with its I2C-programmable counterparts from the same family. The MIC24046 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.

Additional Features
  • 4.5V to 19V input voltage range
  • 5A (maximum) output current
  • High efficiency (>90%)
  • Pin-selectable output voltages:
  • 0.7V, 0.8V, 0.9V, 1.0V, 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V
  • ±1% output voltage accuracy
  • Supports safe start-up with pre-biased output
  • Pin-selectable current limit and switching frequency
  • Internal soft-start and thermal shutdown protection
  • Hiccup-mode short-circuit protection
  • Available in a 20-pin 3mm x 3mm QFN package
  • -40°C to +125°C junction temperature range
