The CXCH7606 is a 180 KHz fixed frequency PWM buck (step-down)DC/DC converter,capable of driving a 2.5A load with high efficiency, lowripple and excellent line and load regulation. Requiring a minimum numberof external components, the regulator is simple to use and include internalfrequency compensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An over current protection function is built inside When short protection function happens, the operation frequency will be reduced from 180KHz to 48KHz. An internal compensation block is built in to minimize external component count.
