DIY Step Down DC /DC Adjustable Regulator Module

This is high performance DC to DC Step
Down Adjustable Regulator Module

Input Voltage: 4 – 25 VDC;

Output Voltage: 1 – 10 VDC ( Default ) or
1.22 – 6.7 V ( more high-precision )

( Adjustable ) (To work normally, the
input voltage must be at least 1.55V higher than the output voltage)

Maximum Current: 3 A

The efficiency can reach 90% -93% with a
quite low heat power!

Dimension: 44 mm*22mm*7.2mm (L*W*H)

If the output side is short-circuited, the
circuit will be automatically protected!

The quiescent current of the circuit is 5
mA.

The input side is connected with a red
LED, while the output side a green LED

The total consumption of the circuit is
about 10 mA.

The value of adjustable resistance on the
circuit board is 50K

Note:-

Input voltage should be 1.55V higher than
the output Voltage for best results

Power Input: Red+ Black- (Please carefully
check the electrodes before connecting to the power supply, make sure your
operation is correct,

otherwise the circuit will be burned)
