This small 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 0.7" × 0.8" yet delivers typical maximum continuous output currents between 2.3 A and 3.4 A, depending on the input voltage, which makes it well suited for powering moderate loads like sensors or small motors.

Product Description

Overview

The D36V28Fx family of buck (step-down) voltage regulators generates lower output voltages from input voltages as high as 50 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters), which makes them much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. These regulators can typically support continuous output currents between 2 A and 4 A, depending on the input voltage and output voltage. In general, the available output current is a little higher for the lower-voltage versions than it is for the higher-voltage versions, and it decreases as the input voltage increases.

The regulators have reverse voltage protection up to 40 V, output undervoltage and overvoltage protection, over-current protection, and short-circuit 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.

Technical Details

Input voltage: 9.8 V to 50 V (minimum input subject to dropout voltage considerations)
Output voltage: 9 V with 4% accuracy
Typical maximum continuous output current: 2.3 A to 3.4 A
Typical efficiency of 85% 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)
1 mA to 3 mA typical no-load quiescent current
Enable input 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: 0.7" × 0.8" × 0.345" (17.8 mm × 20.3 mm × 8.8 mm)
Two 0.086" mounting holes for #2 or M2 screws
