XL2013 General Description The XL2013 is a 150KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 3.2A 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 XL2013 built in output short protection function. When short protection function happens, the chip will be shutdown. An internal compensation block is built in to minimize external component count. Applications n n n Car Charger Battery Charger USB Power Supply Figure1.
