Step-Down DC/DC Voltage Converter 1.8A - Variable Output

DC buck converter module based on the MP2307 IC.
Input 4.75V - 23Vdc.
Output 1V-17Vdc
Output variable by on board miniature preset potentiometer.
Our own tests confirmed an output range of 0-11.2V with a 12V input.
Output current 1.8A max continuous, 3A short duration.
Switching frequency 340kHz.
Note: We measured 12mA drawn from a 12V supply under no load conditions with a consequent warming of the on-board inductor.
Dimensions: 18.5mm x 12.5mm x 4.5mm.
