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 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 (see the \u003ca href=\"#current\"\u003eTypical efficiencies and output currents section\u003c\/a\u003e below for performance graphs ).\u003c\/p\u003e\n\n \u003cp\u003eThese 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).\u003c\/p\u003e\n\n\u003cp\u003e 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:\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e \u003ca href=\"https:\/\/www.pololu.com\/product\/2891\"\u003eU3V70F5: Fixed 5V output\u003c\/a\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e \u003ca href=\"https:\/\/www.pololu.com\/product\/2892\"\u003eU3V70F6: Fixed 6V output\u003c\/a\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e \u003ca href=\"https:\/\/www.pololu.com\/product\/2893\"\u003eU3V70F7: Fixed 7.5V output\u003c\/a\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e \u003ca href=\"https:\/\/www.pololu.com\/product\/2894\"\u003eU3V70F9: Fixed 9V output\u003c\/a\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e \u003ca href=\"https:\/\/www.pololu.com\/product\/2895\"\u003eU3V70F12: Fixed 12V output\u003c\/a\u003e\n\u003c\/li\u003e\n\n\t \u003cli\u003e\u003ca href=\"https:\/\/www.pololu.com\/product\/2896\"\u003eU3V70F15: Fixed 15V output\u003c\/a\u003e\u003c\/li\u003e\n\n\u003cli\u003e \u003ca href=\"https:\/\/www.pololu.com\/product\/2890\"\u003eU3V70A: Precision-adjustable 4.5 – 20 V output\u003c\/a\u003e\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003cp\u003e The different versions of the board all look very similar, so the bottom silkscreen includes a blank space where you can add your own distinguishing marks or labels.\u003c\/p\u003e\n\n\u003cp class=\"note\"\u003e We manufacture these boards in-house at our Las Vegas facility, which gives us the flexibility to make these regulators with custom fixed output voltages between 4.5 V and 20 V.

In our tests with this family of regulator connected with typical power leads (~30″ test clips), we found that input voltages above 17 V caused voltage spikes in excess of 20 V, which could damage the regulator. Lower input voltages caused smaller spikes that could still be problematic for boost regulators operating with the input voltage close to the set output voltage, since input voltages above the set output voltage will propagate to the output and could damage circuits being powered by the regulator. A large electrolytic capacitor (33 μF is a good starting point) can be added close to the regulator between VIN and GND to help suppress these spikes.\u003c\/p\u003e\n\n \u003cp\u003eMore information about LC spikes can be found in our application note, \u003ca href=\"https:\/\/www.pololu.com\/docs\/0J16\"\u003eUnderstanding Destructive LC Voltage Spikes\u003c\/a\u003e .\u003c\/p\u003e","brand":"Pololu","offers":[{"title":"2-4 Weeks","offer_id":47696751591769,"sku":"POL-2896","price":26.28,"currency_code":"EUR","in_stock":true},{"title":"1 day","offer_id":47886012678489,"sku":"POL-2896\/A","price":26.28,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/1009\/7753\/files\/0J9107.1200.jpg?v=1705457336","url":"https:\/\/robot-italy.com\/en\/products\/2896-15v-step-up-voltage-regulator-u3v70f15","provider":"Robot Italy","version":"1.0","type":"link"}
