FEATURES
INTEGRATED SWITCHER Type VDSS(V) 500 MAX ACinput(V) Pout(W) Note 1 10 Descriptions IRIS-A6131 3.95Ω 100/120±15% IRIS-A6131 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 component 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 7 6 NC 5 Startup IRIS-A6131 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 become lower than that of above value. 1 IRIS-A6131ABSOLUTE MAXIMUM RATINGS
(Ta=25℃) Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur.
