Description
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)

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).
