Product Descriptions

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 percent. An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external component count.

The XL4301 built in a simple, user-programmable output cable voltage drop compensation function. Use the curve in Table 2 to choose the proper compensation resistance values for cable compensation.
