KIS-3R33S module
Description

This module comes with output voltage preset to 3.3V. However, it is easy to readjust and have output setat any voltage from 1.21 V – 10.43 V, if the circuit is modified then the output voltage can be varied up to 20V. Different LEDs from different manufacturers operateat different maximum continuous voltage, which in
turn determines the maximum current flowing throughthe LED. To protect LED and to provide stable light characteristics it is necessary to limit the voltage output from the KIS-3R33S module according to the specific requirements for each type of power LED, as specified by the manufacturer.

Description :

The XL4016 is a 180 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 8A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An over current protection function is built inside. When short protection function happens, the operation frequency will be reduced from 180KHz to 48KHz. An internal compensation block is built in to minimize external component count.
