Power Integrations, High Voltage Switcher 24-Pin, InSOP-24D INN4073C-H181-TL

The Power Integration InnoSwitch4-CZ series of ICs partners with the Clamp Zero family of active clamp ICs to dramatically improve the efficiency of flyback power converters, particularly those requiring a compact form-factor. It incorporates primary and secondary controllers and safety-rated feedback into a single IC. It also incorporates multiple protection features including output overvoltage and over-current limiting, and over-temperature shutdown.

Zero voltage switching flyback controller with driver for clamp zero
Steady-state switching frequency up to 140 kHz minimizes transformer size
Synchronous rectification driver and secondary-side sensing
Adjustable accurate output current sense using external sense resistor
