Mini 360 DC Converter Step Down MP2307 Buck Power Supply 4.75V-23V to 1V-17V For Flight Control Car Module

Excellent noise suppression, in the absence of circumstances connected to input audio ear close to the speaker can not hear any noise, two-channel stereo, 5V power supply can output 3W 3W power, can directly drive 4Ω, 8Ω small speakers, the output power large, full of energy, good sound quality. The unique non-LC filter Class-D digital power board can be directly used computer USB power supply.

The module of the IN+ and - after 2~24v, IN adjusting the potentiometer can adjust output voltage, output voltage is greater than the input voltage. Multi-threaded potentiometer turn counter clock wise to increase the output voltages and turn clock wise to decrease the voltages.

Method of use The module of the IN+ and - after 2~24v, IN adjusting the potentiometer can adjust output voltage, output voltage is greater than the input voltage Matters needing attention The input voltage should not exceed the maximum input voltage

The peak current output current is no more than TV university
