DC-DC Voltage Controller 4.0–20V, 12V/24V to 5V 3A Power Supply Module, Mini Adjustable Step-Down Power Supply Module

Module Parameters

• Module type: Non-isolated buck (step-down) synchronous precision module

• Input voltage: DC 4–18V

• Output voltage: Adjustable and fixed integrated output; you can select a fixed output voltage at the back. Operating range (0.8–17V), fixed voltages available (1.8V, 2.5V, 3.3V, 5V, 9V, 12V)

• Output current: 3A (please pay attention to heat dissipation at full load). Actual test at 12V input does not require heat dissipation below 1.5A.

• Conversion efficiency: 97.5% (example: 6.5V input, 5V output, 0.7A load)

• Operating temperature: Industrial grade (-40°C to +85°C). Note: higher ambient temperature reduces output power.

• Static current: 0.85 mA

• Load regulation rate: ±1%

• Voltage regulation rate: ±0.5%

• Dynamic response speed: 5% within 200 µs

• Short-circuit protection: Yes, but avoid prolonged short circuits.

• Output over-voltage protection: No

• Enable control: Yes. High-level signal enables operation, low-level signal stops operation. High level: 2–5V, low level: approx. 0V. Standard setting is connected to the positive input electrode.
