These boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2.5 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 90%. The available output current is a function of the input voltage, output voltage, and efficiency (see Typical Efficiency and Output Current section below), but the input current can typically be as high as 1.4 A. This regulator is with a fixed 12 V output:

Features

  • input voltage: 2.5 V – VOUT
  • fixed 12 V output with 4% accuracy
  • 1.4 A switch allows for input currents up to 1.4 A
  • 2 mA typical no-load quiescent current
  • integrated over-temperature shutoff
  • small size: 0.515″ × 0.32″ × 0.1″ (13 × 8 × 3 mm)
  • Using the Regulator
  • Connections
  • The boost regulator has three connections: input voltage (VIN), ground (GND), and output voltage (VOUT).

The input voltage, VIN, must be at least 2.5 V and should not exceed the output voltage, VOUT. Please be wary of destructive LC spikes that might cause the input voltage to exceed VOUT (see below for more information).

The three connections are labeled on the back side of the PCB, and they are arranged with a 0.1″ spacing along the edge of the board for compatibility with solderless breadboards, connectors, and other prototyping arrangements that use a 0.1″ grid. You can solder wires directly to the board or solder in either the 3×1 straight male header strip or the 3×1 right-angle male header strip that is included.
