DC-DC Step Down Converter 8A

Max 8A 200W DC-DC Step Down Buck Converter Power Supply XL4016 PWM Adjustable 4-40V To 1.25-36V Step-Down Board Module 

Voltage regulator potentiometer counter-clockwise rotation voltage decreases, if the rotation of the copper column voltage has not changed, you can rotate 5-10 laps.

EGP 125.00

Product 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.
