IRIS-G5624A
Features
INTEGRATED SWITCHER
• 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.
Package Outline
• 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
• The built-in power MOSFET simplifies the surge absorption circuit since the
MOSFET guarantees the avalanche energy.

IRIS-G5624A is a hybrid IC consists from power MOSFET and a controller IC, designed for Indirect feed-back QuasiResonant (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).

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are
absolute voltages referenced to terminals stated, all currents are defined positive into any lead. The thermal resistance and power
dissipation ratings are measured under board mounted and still air conditions.

*5 Maximum switching current.
The maximum switching current is the Drain current determined by the drive voltage of the IC and
threshold voltage (Vth) of MOS FET. Therefore, in the event that voltage drop occurs between Pin 2 and
Pin 3 due to patterning, the maximum switching current decreases as shown by V2-3 in Fig.1
Accordingly please use this device within the decrease value, referring to the derating
curve of the maximum switching current.
