5V Step-Up/Step-Down Voltage Regulator S13V30F5

5V Step-Up/Step-Down Voltage Regulator S13V30F5

CHF12.95

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 0.9″ × 0.9″, 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.

The S13V30F5 switching regulator (also called a switched-mode power supply (SMPS) or DC-to-DC converter) uses a buck-boost topology to convert both higher and lower input voltages to a regulated 5 V output. It takes input voltages from 2.8 V to 22 V and increases or decreases them as necessary, offering a typical efficiency of over 85% and a typical output current of 3 A. The flexibility in input voltage is especially well-suited for battery-powered applications in which the battery voltage begins above 5 V and drops below as the battery discharges. Without the typical restriction on the battery voltage staying above the required voltage throughout its life, new battery packs and form factors can be considered.

The regulator has input reverse voltage protection up to 20 V, under-voltage lockout, output over-voltage protection, and over-current protection. A thermal shutdown feature also helps prevent damage from overheating and a soft-start feature limits the inrush current and gradually ramps the output voltage on startup.

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)
  • Typical efficiency of 85% to 95%, depending on input voltage and load (see the efficiency graph)
  • 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: 0.9″ × 0.9″ × 0.38″ (22.9 mm × 22.9 mm × 9.7 mm); 
  • Two 0.086″ mounting holes for #2 or M2 screws
