CX8517 Overview
The CX8517 is a 180 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 3.5A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external ponents, the regulator is simple to use and include internal frequency pensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%.
