IRIS-X6757
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
Pulse-by-Pulse Overcurrent Protection (OCP)
Overvoltage Protection with Latch mode (OVP)
Overload Protection with Latch mode (OLP)
The maximum limit of on-time
Package Outline
TO-220 Fullpack (7 Lead)
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.

Key Specifications
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.
