XL4201 DC to DC Step Down Buck Converter IC 

XL4201 3 Ampere 150KHz 40 Volts Buck DC/DC Converter With Constant Current Loop

The XL4201 is a 150KHz fixed frequency PWM buck (step-down) DC/DC Converter, capable of driving a 2.5 Ampere 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 in XL4201 IC is able to adjust the duty ratio linearly from 0 to 100%. An enable function, an over current protection function is built inside. An internal compensation block is built into minimize external component count. 

DNA solutions, Nashik has various types of DC to DC converter IC. Check out our complete collection of Voltage Regulator and Step up and Step Down IC's.

If you are in Nashik you can buy this Electronic Component at our local shop at New CBS, Nashik or you can place order online and get it delivered at your doorstep anywhere in India.
