INN4077C - H181

InnoSwitch4 - CZ series IC and ClampZero series of active clamp using IC collocation, can significantly improve the efficiency of the flyback type power transformer, especially suitable for those with compact appearance requirements of the converter design applications.InnoSwitch4 - CZ series products will be the primary and secondary controller and conform to the safety standards of feedback mechanism is integrated in a single IC.

InnoSwitch4 - CZ combined with ClampZero, greatly reduces the system and the primary switch loss, and can achieve high power density.InnoSwitch4 - CZ also integrates various protection features, including the output over voltage, over current limiting and thermal shut off protection.Device support provided by the latch and the common combination of automatic restart protection mode, this is the charger, adapter, consumer electronics and industrial systems and other application required features.
