Package Outline
INTEGRATED SWITCHER
Features
• 7-pin SIP type full molded package, optimum IC for low-height SMPS.
• 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)
•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 step drive circuit
• Built-in low frequency PWM mode ( 22 kHz)
• UVLO Burst Standby
• Two operational modes by auto switching functions according to load
ꢀ For middle~heavy load operation : QR mode
ꢀ For light~middle load operation : 1 Bottom Skip mode
• Various kinds of protection functions

Description
IRIS-X6757 is a hybrid IC consisting of a power MOSFET and a controller IC, designed for Quasi-Resonant (including low frequency PWM)
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 component count and simplifying the circuit design.

Note 1:
The Pout (W) represents the thermal rating at Quasi-Resonant operation, and the peak power output is obtained by approximating 120 to
140 % of the above listed value. When the output voltage is low, and the ON-duty is narrow, the Pout (W) shall become lower than that
of the above.

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.
