... Thermal Shutdown with latch mode (TSD) Descriptions IRIS-F6426S is a hybrid IC consists from power MOSFET and a controller IC, designed for Quasi-Resonant (including low frequency PRC) fly-back converter type SMPS (Switching Mode Power Supply) applications. This IC realizes high efficiency, low noise, downsizing and standardizing of a power supply system reducing external components count and simplifying the circuit designs. (Note). PRC is abbreviation of “ ...

... IRIS-F6426S Absolute Maximum Ratings (Ta=25ºC) Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to terminals stated, all currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions. ...
