STR-A6372

IRIS-A6372 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) Type INTEGRATED SWITCHER Package Outline 8 Lead PDIP Key Specifications MOSFET VDSS(V) 900 RDS(ON) MAX 7.7Ω AC input(V) 230±15% IRIS-A6372 85 to 264 Pout(W) Note 1 6 4 Descriptions IRIS-A6372 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 standardizing of a power supply system reducing external components count and simplifying the circuit designs. (Note). PRC is abbreviation of “Pulse Ratio Control” (On-width control with fixed OFF-time). Typical Connection Diagram STR-A6372 1 2 3 4 8 7 6 5 www.irf.com IRIS-A6372 A...
