NCP1288 Fixed Frequency Current Mode Controller for Flyback Converters The NCP1288 is a new generation of the NCP12xx fixed−frequency current−mode controllers featuring a high−voltage startup current, pin−to−pin compatible with the previous generation. http://onsemi.com Due to its proprietary Soft−Skip™ mode combined with frequency foldback, the controller exhibits excellent efficiency in light load condition while still achieving very low standby power consumption. This Soft−Skip feature also dramatically reduces the risk of acoustic noise, which enables the use of inexpensive transformers and capacitors in the clamping network.
