1.With voltage meter display;voltage meter error of ±0.1V;the range among 0~40V. (note: to ensure the voltage meter accuracy, please make sure that the input voltage is 4.2V or more).
2.Voltage meter can be closed by long pressing button(minimum power loss).
3.The range of input voltage is 4.2~40V and output voltage is1.25V~37V ,which are continuously adjustable.(The input voltage must 1V higher than output voltage)
4.Maximum output current can be as high as 3A,but normal and stable working current is2A.
5.Use 150KHZ internal oscillation frequency,which is belong to the second generation of switch voltage regulator with low consumption and high efficiency.
Where to use:
2.temporarily set up power supply in the outdoor
3.car(audio, electric fan)power supply
What is special:
LM2596 Step Down Power Module design based on XL2596 as main control chip,attached digital tube to display voltage at that time to highlight smart function. What’more, schottky diode provides protection of reverse connection.
What components and tools do you need to do the test:
Step 1: Function Introduction
Step 2: Diagram
Step 3: Testing Results:Input Voltage 4.5V
Step 4: Testing Results:Input Voltage 30V
In general, the performance of LM2596 Step Down Power Module is very good.You had better set the output voltage 3~4V lower than the input voltage, then the testing results will be more stable.
