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 the Maximum continuous output current section 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 similar D36V28Fx family of step-down voltage regulators, which can deliver up to 4 A in a wide range of output voltages.
