Description

XL1509-3.3V 2A Step-Down Buck Converter IC – SOP-8 Package

The XL1509 is a 150 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 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 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. When the second current limit function happens, the operation frequency will be reduced from 150KHz to 50 KHz. An internal compensation block is built in to minimize external component count.
