..
Data Sheet No. PD 96947A
Features
- Oscillator is provided on the monolithic control with adopting On-Chip Trimming technology.
- Small temperature characteristics variation by adopting a parator to pensate for temperature on the control part.
- Low start-up circuit current (100u A 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
- Built-in soft drive circuit
- Built-in low frequency PRC mode (≒20k Hz)
- Various kinds of protection functions
- Pulse-by-pulse Overcurrent Protection (OCP)
- Overvoltage Protection with latch mode (OVP)
- Thermal Shutdown with latch mode (TSD)

Descriptions
120±15% 100 1 .3Ω IRIS-G6623 450 Note 1: The Pout (W) represents the thermal rating at Quasi-Resonant 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 bee lower than that of above.
IRIS-G6623 is a hybrid IC consists from power MOSFET and a controller IC, designed for Quasi-Resonant (including low frequency PRC) fly-back converter type SMPS (Switching Mode Power Supply) applications. This IC realizes high efficiency, low noise, downsizing and standardizing of a power supply system reducing external ponents count and simplifying the circuit designs. (Note). PRC is abbreviation of “Pulse Ratio Control” (On-width control with fixed OFF-time).
