SKU: REG-020 Manufacturer: Pololu Mfg Part Number: 2895



This powerful synchronous switching boost regulator efficiently generates an output voltage of 12V from an input voltage as low as 2.9V while using an input current as high as 7A. This regulator features reverse voltage protection, and unlike most boost regulators, it offers a true shutdown option that turns off power to the load.

Input currents of around 6A can typically be maintained for many minutes without triggering thermal shutdown, though the actual performance depends on depending on the input and output voltages as well as external factors such as ambient temperature and airflow. For boost regulators, the output current equals the input current times the efficiency times the ratio of VIN to VOUT, so the more you are boosting, the lower the maximum output current will be.


  • Input voltage: 2.9V to 12V
  • True shutdown option turns off power to the load
  • Instantaneous input currents up to 10A
  • Input currents up to 7A for several seconds
  • Input currents up to 6A for prolonged durations
  • Over-temperature shutoff
  • Cycle-by-cycle input current limiting to 10A
  • Two mounting holes for #2 or M2 screws
  • Weight: 3.5 g
  • Output voltage: 12V
  • Typical efficiency of 80% to 95%, depending on input voltage and load
  • Low quiescent current
  • Reverse voltage protection
  • Short-circuit protection with hiccup recovery
  • Under-voltage lockout
  • Dimensions: 40.6 × 15.2 × 4.6mm (1.6 × 0.6 × 0.18″)
