Descripción

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 0.35″ × 0.475″, has a typical efficiency of 85% to 95%, and can supply typical continuous output currents between 1 A and 2.5 A depending on the input voltage.

Features
  • Input voltage: 2.8 V to 22 V
  • Output voltage: 5 V with 3% accuracy
  • Typical maximum continuous output current: 1 A to 2.5 A, depending on input voltage
  • Typical efficiency of 85% to 95%, depending on input voltage and load
  • 10 mA to 20 mA typical no-load quiescent current
  • Input under-voltage lockout and output over-voltage protection
  • Soft-start feature limits inrush current and gradually ramps output voltage
  • Over-current protection and over-temperature shutoff
  • 5 A output current limit
  • Fixed switching frequency of ~500 kHz
  • Compact size: 0.35″ × 0.475″ × 0.22″ (8.9 mm × 12.1 mm × 5.6 mm);
