XL4301 DC to DC Buck Converter IC 

XL4301 3 Ampere 180KHz 45 Volts Buck DC to DC Converter With Constant Current Loop

The XL4301 is a 180KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 2.5A 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. The PWM Control circuit 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. The XL4301 Step Down DC to DC Buck IC built in a simple, user-programmable output cable voltage drop compensation function.

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.
