XL4005 Step Down Power Module

The XL4005 Power supply module is based on the XL4005 Dc-Dc converter IC. The module can step-down and regulate a voltage from 0.8V to 32V based on the position of the potentiometer. The Potentiometer used here is a 25-turn potentiometer that provides easy adjustment of the output of the module to exactly the voltage application needs. The maximum output current can go as high as 5A making it suitable to power heavy loads like CNC machines, Robotic Arms or even to charge batteries. 

It works with fixed 300 kHz frequency and uses a PWM buck feature where the maximum duty cycle is 100%. It has excellent low ripple and regulation features. A built-in current limit feature along with the thermal shutdown is also available in this module. In-Built output short protection circuits are also useful for safety. It does not include any Input reverse polarity protection, although high current diodes in series can be useful in such cases. It is high frequency module with 5V-32V input voltage.
