IRIS-W6753 Description
IRIS-W6753 is a hybrid IC consisting of a power MOSFET and a controller IC, designed for Quasi-Resonant (including low frequency PWM) 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 ponent count and simplifying the circuit design. Typical Connection Diagram Note.
