DC-DC Adjustable Step-Down Power Supply Module -XL4005
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.
