U3V70x Step-Up Voltage Regulators

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 2.9 V. The regulators actively limit the instantaneous input currents to 10 A, and the input current can typically be as high as 8 A for several seconds before the thermal protection activates. Input currents of around 6 A 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 is approximately proportional to the ratio of the input voltage to the output voltage, so the more you are boosting, the lower the maximum output current will be (see the product pages for performance graphs).

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).

The U3V70x family includes six versions with fixed output voltages ranging from 5 V to 15 V as well as an adjustable version that can be set anywhere between 4.5 V and 20 V using a precision 12-turn potentiometer:
