This powerful synchronous switching step-down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 9 V. The board measures only 1″ × 1″ yet delivers typical maximum continuous output currents between 2.7 A and 7 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: 9.9 V to 50 V
Output voltage: 9 V with 4% accuracy
Typical maximum continuous output current: 2.7 A to 7 A
Typical efficiency of 80% 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: 9.9 V
Maximum operating voltage: 50 V
Continuous output current: 5 A
Output voltage: 9 V
Reverse voltage protection?: Y
Maximum quiescent current: 4 mA
Output type: fixed 9V
