OF THE SI9114A BID/CMOS PWM CONTROLLER The Si9114A controller is similar in configuration to the Si9110. It uses a traditional constant frequency current mode control, the most commonly used architecture.The duty cycle is limited to less than 50% to avoid problems with core reset.Current mode control is presently the de-facto standard for PWM control circuits.Indeed, it is the only candidate that should be considered, given its many advantages: S Cycle by cycle current limit protection S Simp
