IRIS-A6331

Data Sheet No. PD 96935A IRIS-A6331 Features Oscillator is provided on the monolithic control with adopting On-ChipTrimming technology. Small temperature characteristics variation by adopting a comparator to compensate for temperature on the control part. Low start-up circuit current (50uA max) Built-in Active Low-Pass Filter for stabilizing the operation in case of light load Avalanche energy guaranteed MOSFET with high VDSS The built-in power MOSFET simplifies the surge absorption circuit since the MOSFET guarantees the avalanche energy. No VDSS de-rating is required. Built-in constant voltage drive circuit Various kinds of protection functions Pulse-by-pulse Overcurrent Protection (OCP) Overvoltage Protection with latch mode (OVP) Thermal Shutdown with latch mode (TSD) INTEGRATED SWITCHER Package Outline 8 Lead PDIP Key Specifications Type IRIS-A6331 MOSFET VDSS(V) 500 RDS(ON) MAX 3.95Ω ACinput(V) 100/120±15% Pout(W) Note 1 10 Note1: The Pout (W) represents the thermal rating at PRC Operation, and the peak power output is obtained by approximately 120 to 140% of the above listed. When the output voltage is low and ON-duty is narrow, the Pout (W) shall become lower than that of above. Descriptions IRIS-A6331 is a hybrid IC consists from 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 stan...
