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 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.

Features

Input voltage: 5.5 V to 50 V (minimum input subject to dropout voltage considerations; see the dropout voltage section for details)
Output voltage: 5 V with 4% accuracy
Typical maximum continuous output current: 3.5 A to 8 A (see the maximum continuous output current graph below)
Typical efficiency of 80% to 95%, depending on input voltage, output voltage, and load (see the efficiency graph below)
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 the quiescent current graph below)
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 M2 screws

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.
