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).

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.
