Current output: 1.5a
Voltage input: 4.2 ~ 40 V
Working temperature: 0 ° C to 125 ° C
Characteristic frequency: 100 (MHz)
Module size: 35.6(mm)x16.8(mm)
Input mode: VIN input positive level, GND input negative pole
Output mode: VOUT output positive level, GND output negative pole
Maximum output current: maximum output current =3/(input voltage - output voltage)
In order to improve the efficiency, it is better to have a voltage difference of 3V between input and output. However, the maximum voltage difference between input and output should not exceed 30V, that is, input-output 30V, otherwise it is easy to burn the module.
As it is a linear step-down dc-dc circuit, the input voltage shall be more than 3V higher than the output voltage to ensure the stability of the output voltage.
Input voltage: 40v-4.5v (the highest limit measured in our store can reach 40V),
Adjustment mode: firstly connect the input power correctly (between 40-4.5), then use a multimeter to monitor the output voltage and adjust the potentiometer (generally turn to boost voltage in advance, turn to decrease voltage in reverse).
Tips: when adjusting the voltage, please pay attention to adjust the required voltage in the absence of load
