Category:

This boost (step-up) voltage regulator generates higher output voltages from input voltages as low as 2.5 V. The switching regulator (also called a switched-mode power supply (SMPS) or DC-to-DC converter) and have a typical efficiency between 80% to 90%. The available output current is a function of the input voltage and output voltage, the input current can typically be as high as 1.4 A.

  • input voltage: 2.5 V – VOUT
  • fixed 5V output with 4% accuracy
  • 1.4 A switch allows for input currents up to 1.4 A
  • 2mA typical no-load quiescent current integrated over-temperature shutoff
  • small size: 0.515″ × 0.32″ × 0.1″ (13 × 8 × 3 mm)

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 the note below).

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.

 

LC Voltage Spikes

When connecting voltage to electronic circuits, the initial rush of current can cause damaging voltage spikes that are much higher than the input voltage. You can suppress such spikes by soldering a 33μF or larger electrolytic capacitor close to the regulator between VIN and GND.
