The D24V22Fx family of step-down voltage regulators generates lower output voltages from input voltages as high as 36 V. They are synchronous switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) with typical efficiencies of 85% to 95%, which is 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 1.4 A and 2.6 A, though the actual available output current is a function of the input voltage and efficiency (see the Typical efficiency and Maximum continuous output current sections 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.

Versions:

D24V22F3: Fixed 3.3V output
D24V22F5: Fixed 5V output
D24V22F6: Fixed 6V output
D24V22F7: Fixed 7.5V output
D24V22F9: Fixed 9V output
D24V22F12: Fixed 12V output

Features:

Input voltage:
- 4 V to 36 V for the version that outputs 3.3 V
- [output voltage + dropout voltage] to 36 V for output voltages of 5 V and higher (see the dropout voltage section for details)
Fixed 3.3 V, 5 V, 6 V, 7.5 V, 9 V, or 12 V output (depending on regulator version) with 4% accuracy
Typical maximum continuous output currents between 1.4 A abd 2.6 A (see the maximum continuous output current graph below)
Typical efficiency of 85% to 95%, depending on input voltage, output voltage, and load (see the efficiency graph below)
Switching frequency: ~400 kHz
Integrated reverse-voltage protection, over-current and short-circuit protection, over-temperature shutoff, and soft-start
1 mA typical no-load quiescent current; this can be reduced to approximately 5 µA to 10 µA per volt on VIN by disabling the board (see the quiescent current graph below)
“Power good” output indicates when the regulator cannot adequately maintain the output voltage
Compact size: 0.7″ × 0.7″ × 0.31″ (17.8 mm × 17.8 mm × 8 mm)
Two 0.086″ mounting holes for #2 or M2 screws
