{"title":"12V Step-Up Voltage Regulator U3V16F12","handle":"12v-step-up-voltage-regulator-u3v16f12","url":"/products/12v-step-up-voltage-regulator-u3v16f12","description":"The Pololu U3V16F12 is a compact switching step-up (boost) voltage regulator that generates a fixed 12V output from input voltages as low as 1.3V (after start-up). It handles continuous input currents up to approximately 1.5A with a typical efficiency of 85–95%, making it ideal for battery-powered projects that need a stable 12V rail.\n\nThe board measures just 0.32″ × 0.515″ with 0.1″ pin spacing, so it drops straight into standard breadboards and perfboards. A minimum start-up voltage of 2.7V is required, but once running, the regulator continues to operate with inputs down to 1.3V.\n\nKey Features\n\n\n12V Fixed Output – Stable boost output from inputs as low as 1.3V (2.7V minimum start-up)\n\nHigh Efficiency – 85–95% typical switching efficiency\n\n1.5A Continuous Input Current – With 2A instantaneous current limiting\n\nUltra-Compact – 0.32″ × 0.515″ board with 0.1″ pin spacing\n\nBuilt-In Protections – Cycle-by-cycle current limiting, under-voltage lockout, and over-temperature shutdown\n\n\nSpecifications\n\n\nOutput Voltage – 12V (fixed)\n\nInput Voltage – 1.3V minimum operating / 2.7V minimum start-up\n\nMax Continuous Input Current – ~1.5A (up to ~1.6A for short durations)\n\nInstantaneous Current Limit – 2A\n\nEfficiency – 85–95% typical\n\nBoard Dimensions – 0.32″ × 0.515″ (8.1 × 13.1 mm)\n\nPin Spacing – 0.1″ (2.54 mm)\n\n\nIdeal For\n\nBoosting single-cell or multi-cell battery packs to 12V\nPowering 12V sensors, relays, or LEDs from lower-voltage sources\nCompact embedded systems needing a 12V supply rail\nBreadboard and perfboard prototyping\n\n\nPackage Contents\n\n1× U3V16F12 Step-Up Voltage Regulator\n\n\n\nWarning: This boost regulator connects the input to the output through an inductor and diode with no isolation. The input voltage passes through to the output even when the regulator is disabled. Do not expose to short circuits or excessive loads, and do not apply reverse voltage — doing so will damage the regulator.\n\n\n\nNote: The output current available depends on the boost ratio (VOUT / VIN). The higher the boost ratio, the lower the maximum output current. For example, boosting from 3.3V to 12V yields less output current than boosting from 5V to 12V.\n","vendor":"Pololu","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":14667,"title":"Default Title","sku":"PL-4945","price":13.25,"on_sale":false,"in_stock":true,"available_quantity":9,"option1":"Default Title"}]}
