CX8517 3.5A 180KHz 36V DC-DC buck converter constant-current / constant-voltage loop chip overview CX8517 is a 180KHz fixed frequency PWM step-down DC / DC converter capable of driving 3.5A load high efficiency, low ripple and excellent line and load regulation. Require a minimum of external components, the regulator is simple to use and include internal frequency compensation fixed frequency oscillator. PWM control circuit capable of adjusting the duty cycle linearly from 0% to 100%. Built-in overcurrent protection. When the case of short-circuit protection, the operating frequency will be reduced from 180KHz down to 48KHz. Built-in internal compensation modules to minimize the number of external components.
