Module XL4016E1+R step-down DC-DC converter with regulator Uin 4-40V, Uout 1.25-36V, 8A, 180KHz

This module is a DC voltage buck converter. The task of the module is to convert the input voltage to the required value of the output voltage. The converter can be used as: a power supply, a power supply for high-power LEDs, etc.

The converter is designed based on the XL4016 chip. The chip is mounted on a heatsink and isolated for user safety. The microcircuit has protection against short circuit and overheating. When the overheating protection is triggered, the module automatically cuts off the input voltage. The efficiency of the converter is 93%. The maximum output power of the voltage converter is 100 W, and the conversion frequency is 180 kHz. Changing the DC output voltage is carried out using a variable resistor, on the handle of which a cap is installed for convenient parameter adjustment.

There are 2 terminal blocks (4 pins) for connecting an external power source and a device:

IN+: input supply voltage 4 - 40 V
IN-: "ground"
OUT+: output supply voltage 1.25 - 36 V
OUT-: "ground"

There are also 2 LEDs on the board:

L: indicates that the input voltage is applied to the module
R: Indicates that output voltage is being supplied to the device

The maximum output current of the module is 8 A. The installed heatsink can be replaced with a more powerful one.

Power is supplied to the converter from an external power source. The input supply voltage range is from 4 to 40 V, and the output voltage range is from 1.25 to 36 V.
