Description



Features:

*Oscillator is provided on the monolithic control with adopting On-Chip- Trimming 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)
*OvervoltageProtection with latch mode (OVP) Key Speci
*Thermal Shutdown with latch mode (TSD)

Description

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 IRIS-A6372 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).
