Features INTEGRATED SWITCHER Pout(W) Note 1 7 5 Descriptions IRIS-A6159 is a hybrid IC consisting of a power MOSFET and a controller IC, designed for PRC fly-back converter type SMPS (Switching Mode Power Supply) applications, applicable for PRC operation for small power SMPS. This IC realizes downsizing and standardizing of a power supply system reducing external ponent count and simplifying the circuit design. Note: PRC is abbreviation for “Pulse Ratio Control” (On-width control with fixed OFF-time). Typical Connection Diagram 8 D D 6 NC Startup IRIS-A6159 OCP 1 Vcc 2 GND 3 FB 4 Note 1: The pout (W) represents the thermal rating at PRC Operation. The peak power output is obtained by approximating 120 to 140% of the above listed value. When the output voltage is low and ON-duty is narrow, the Pout (W) shall bee lower than that of above value. .irf. Free Datasheet http://.. IRIS-A6159 Absolute Maximum Ratings (Ta=25℃) 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.
