Product Description

Overview

The D36V50Fx 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 9 A, depending on the input voltage and output voltage (see theMaximum continuous output currentsection below). 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.

This family includes six versions with fixed output voltages ranging from 3.3 V to 12 V:

D36V50F3: Fixed 3.3V output
D36V50F5: Fixed 5V output
D36V50F6: Fixed 6V output
D36V50F7: Fixed 7.5V output
D36V50F9: Fixed 9V output
D36V50F12: Fixed 12V output

The regulators have input 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.

If you do not need quite as much current, consider the very similarD36V28Fx familyof step-down voltage regulators, which can deliver up to 4 A in a wide range of output voltages.

We manufacture these boards in-house at our Las Vegas facility, which gives us the flexibility to make these regulators with customized components to better meet the needs of your project. For example, if you have an application where the input voltage will always be below 20 V and efficiency is very important, we can make these regulators a bit more efficient at high loads by replacing the 40V reverse voltage protection MOSFET with a 20V one. We can also customize the output voltage. If you are interested in customization, pleasecontact us.

Features

Input voltage: 9.9 V to 50 V (minimum input subject to dropout voltage considerations; see thedropout voltage sectionfor details)
Output voltage: 9 V with 4% accuracy
Typical maximum continuous output current: 2.7 A to 7 A (see themaximum continuous output current graphbelow)
Typical efficiency of 85% to 95%, depending on input voltage, output voltage, and load (see theefficiency graphbelow)
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 (see thequiescent current graphbelow)
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: 1″ × 1″ × 0.375″ (25.4 mm × 25.4 mm × 9.5 mm)
Three 0.086″ mounting holes for #2 or M2screws

Notes:

1. Without included optional headers.
2. Subject to dropout voltage considerations. See the dropout voltage graph under the description tab for more information.
3. Typical continuous output current at 36 V in. Actual achievable continuous output current is a function of input voltage and is limited by thermal dissipation. See the output current graph under the description tab for more information.
4. To -40 V. Connecting supplies over 40 V in reverse can damage the device.
5. While enabled with no load. Can be reduced to under 1 mA using the enable pin.
