Coilcraft CPS

Transformers for Capacitor Charging

Coilcraft’s selection of flyback transformers for capacitor charging handle a range of 1.2 A to 50 A peak primary current for fast charging. Many are designed for a maximum capacitor charge voltage of up to 500 V and come in various pri-sec turns ratios up to 1:15. Reference designs include ON NCP5080, LT3451, and many for Linear Technology / Analog Devices LT3750 and LT3751 controller ICs. Applications include photoflash charging and general purpose capacitor charging.
