Adjustable 4-12V Step-Up Voltage Regulator U3V50ALV Pololu 2570
These adjustable boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2.9 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 95%. The available output current is a function of the input voltage, output voltage, and efficiency (see the Typical Efficiency and Output Current section below), but the input current can typically be as high as 5 A. The U3V50x regulator family includes two adjustable-output versions: the U3V50ALV offers an output range of 4 V to 12 V and the U3V50AHV offers an output range of 9 V to 30 V. Versions of this regulator are also available with a fixed 5 V, 6 V, 9 V, 12 V, or 24 V output:
