Click here to be notified by email when DC-DC Adjustable Step-Down Power Supply Module -XL4005 becomes available.

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 include internal frequency compensation and a fixed-frequency oscillator.


DIY mobile power supply, car power, communications equipment power supply, etc.


  • Input voltage: 5-32V (input should try not to exceed 38V)
  • Output voltage: 0.8-32V continuously adjustable   
  • Output current: 0-5A, recommended for use within 3.5A.
  • Output power: recommended in the use of 75W, more than 50W please add heat sink.
