RT8272 Variable Voltage Step Down Module - 3A / 1-15V

The RT8272 DC Voltage Regulator is based on the RT8272 Dc-Dc converter IC. The module can step-down and regulate a voltage from 4.75V to 23V based on the position of the potentiometer. The Potentiometer used here is a small SMD 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 3A making it suitable to power different circuits that need input from a battery but are unable due to the low battery voltage. 

It works with a fixed 1.2 MHz frequency and uses a PWM buck feature where the maximum duty cycle is automatically changed depending on the load. It has excellent low ripple and regulation features. A built-in Cycle by Cycle over current limit feature along with the thermal shutdown is also available in this module. It is high frequency module with 4.75V-24V input voltage
