Pololu Boost Regulator, Vin 2.9-20V, Vout 4.5-20V 8A, Fine Adjust

This powerful synchronous switching boost regulator efficiently generates a finely adjustable output voltage between 4.5V to 20V from an input voltage as low as 2.9V while using an input current as high as 8A. This regulator features reverse voltage protection, and unlike most boost regulators, it offers a true shutdown option that turns off power to the load.

The U3V70x boost (step-up) voltage regulators are high-current, high-efficiency synchronous switching regulators that generate higher output voltages from input voltages as low as 2.9V. The regulators actively limit the instantaneous input currents to 10A, and the input current can typically be as high as 8A for several seconds before the thermal protection activates. 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.

These regulators feature a variety of built-in protections, including reverse voltage protection to keep your load safe in the event power is accidentally connected backward, and unlike most boost regulators, these units offer a true shutdown option that turns off power to the load (with typical boost regulators, the input voltage will pass directly through to the output when they are disabled).
