Features
INTEGRATED SWITCHER
• 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.
Package Outline
• 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)
8 Lead PDIP
• Overvoltage Protection with latch mode (OVP)
• Thermal Shutdown with latch mode (TSD)

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).
