Description

This powerful synchronous switching step-down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 12 V. The board measures only 1" × 1" yet delivers typical maximum continuous output currents between 2.3 A and 6.5 A, depending on the input voltage, which makes it well suited for powering moderate to large loads. An optional enable input with a precise cutoff threshold can be used to put the regulator in a low-power state with a current draw of 10 µA to 20 µA per volt on VIN. The regulator also features reverse voltage protection and a power-good output that indicates when the regulator cannot adequately maintain the output voltage.

Features:

  • Input voltage: 13.3 V to 50 V
  • Output voltage: 12 V with 4% accuracy
  • Typical maximum continuous output current: 2.3 A to 6.5 A
  • Typical efficiency of 90% to 95%, depending on input voltage, output voltage, and load
  • Switching frequency: ~500 kHz under heavy loads
  • Power-save mode with ultrasonic operation that increases light load efficiency by reducing switching frequency, but keeps it above the audible range (20 kHz)
  • 2 mA to 4 mA typical no-load quiescent current
  • Enable input with precise cutoff threshold for disconnecting the load and putting the regulator into a low-power state that draws approximately 10 µA to 20 µA per volt on VIN
  • "Power good" output indicates when the regulator cannot adequately maintain the output voltage
  • Output undervoltage and overvoltage protection
  • Soft-start feature limits inrush current and gradually ramps output voltage
  • Integrated reverse-voltage protection up to 40 V, over-current and short-circuit protection, over-temperature shutoff
  • Compact size: 25.4 mm × 25.4 mm × 9.5 mm
  • Three 0.086" mounting holes for #2 or M2 screws


Specifications:

  • Minimum operating voltage: 13.3 V
  • Maximum operating voltage: 50 V
  • Continuous output current: 4.5 A
  • Output voltage: 12 V
  • Reverse voltage protection?: Y
  • Maximum quiescent current: 4 mA
  • Output type: fixed 12V
