iris-g6624
Description
Integrated Switcher
Manufacturer
International Rectifier Corp.
Datasheet
• 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 (100uA max)
• Built-in Active Low-Pass Filter for stabilizing the operation in case of light
load
• Avalanche energy guaranteed MOSFET with high VDSS
• Built-in constant voltage drive circuit
• Built-in soft drive circuit
• Built-in low frequency PRC mode (≒20kHz)
• Various kinds of protection functions
Descriptions
IRIS-G6624 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 components count and
simplifying the circuit designs.
(Note). PRC is abbreviation of “Pulse Ratio Control” (On-width control with fixed OFF-time).
Features
Typical Connection Diagram
• The built-in power MOSFET simplifies the surge absorption circuit since
the MOSFET guarantees the avalanche energy.
• No VDSS de-rating is required.
• Pulse-by-pulse Overcurrent Protection (OCP)
• Overvoltage Protection with latch mode (OVP)
• Thermal Shutdown with latch mode (TSD)

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 become lower than that of above.
