The XL4005 is a 300KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 5A 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 includes internal frequency compensation and a fixed-frequency oscillator.

The step-down module can easily reach 4A, 50W, add heat sink can reach 75W. 

Module window: 5 A high-power high-efficiency low ripple
