Xinlong Semiconductor Technology XL9021
The XL9021 is a 150KHz fixed frequency PWM synchronous buck DC/DC converter, capable of driving a 2.5A load with high efficiency, low ripple and excellent line and load regulation. The XL9021 has built-in thermal shutdown, current limit protection and output short protection function and so on. When the output short protection function happens, the operation frequency will be reduced about from 150KHz to 40KHz.FEATURES
