Pololu 4.5-20V Fine-Adjust Step-Up Voltage Regulator U3V70A.The U3V70A is a high-efficiency step-up (boost) voltage regulator that converts input voltages as low as 2.9V to an adjustable output between 4.5V and 20V. It features a precision 11-turn potentiometer for fine-tuning the output voltage. The regulator can handle instantaneous input currents up to 10A and maintain continuous currents around 6A to 7A, depending on thermal conditions. Integrated protections include reverse voltage, short-circuit, over-temperature shutoff, and under-voltage lockout.
Note: Ensure the input voltage does not exceed the set output voltage to prevent potential damage to the regulator and connected components.
Features:
- Input voltage: 2.9 V to VOUT
- Output voltage: 4.5 V to 20 V (precision-adjustable using built-in 11-turn potentiometer)
- True shutdown option turns off power to the load
- Typical efficiency of 80% to 95%, depending on input voltage, output voltage, and load
- 10 A switch allows for:
- Instantaneous input currents up to 10 A
- Input currents up to 8 A for several seconds
- Input currents around 6 A to 7 A for prolonged durations, depending on input voltage and output voltage
- low quiescent current for most combinations of input and output voltages
- Integrated protections:
- Reverse voltage protection
- Short-circuit protection with hiccup recovery
- Over-temperature shutoff
- Under-voltage lockout (typical thresholds are 2.4 V falling, 2.8 V rising)
- Cycle-by-cycle input current limiting to 10 A
