This powerful synchronous switching step-up/step-down regulator efficiently produces 5 V from input voltages between 2.8 V and 22 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 5 V. The board measures 22.9mm x 22.9mm, has a typical efficiency of 85% to 95%, and can supply typical continuous output currents between 2 A and 4 A depending on the input voltage. The regulator also features reverse voltage protection and an optional enable input that can be used to put the regulator in a low-power state with a current draw of less than 10 µA per volt on VIN.

Features:
  • Input voltage: 2.8 V to 22 V
  • Output voltage: 5 V with 3% accuracy
  • Typical maximum continuous output current: 2 A to 4 A, depending on input voltage (see the maximum continuous output current graph below)
  • Typical efficiency of 85% to 95%, depending on input voltage and load (see the efficiency graph below)
  • 10 mA to 20 mA typical no-load quiescent current (see the quiescent current graph below); can be reduced to 2 µA to 10 µA per volt on VIN by disabling the board
  • Input under-voltage lockout and output over-voltage protection
  • Soft-start feature limits inrush current and gradually ramps output voltage
  • Integrated reverse-voltage protection up to 20 V, over-current protection, and over-temperature shutoff
  • Fixed switching frequency of ~500 kHz
  • Compact size: 22.9 mm × 22.9 mm × 9.7 mm; see the dimension diagram for more information
  • Two 0.086? mounting holes for #2 or M2 screws

Specs:
  • Minimum operating voltage: 2.8 V
  • Maximum operating voltage: 22 V
  • Continuous output current: 3 A
  • Output voltage: 5 V
  • Reverse voltage protection?: Y
  • Maximum quiescent current: 100 mA
  • Output type: fixed 5V
