com IRIS-W6753 Features • 6-pin SIP type full molded package, optimum IC for low-height SMPS, with distance between high and low voltage pin 1.
8 mm with pin elimination.
• 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 TO-220 Fullpack (7 Lead modified) • 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 Key Specifications • Various kinds of protection functions MOSFET RDS(ON) Pout(W) Pulse-by-Pulse Overcurrent Protection (OCP) T ype VDSS(V) MAX AC input(V) Note 1 Overvoltage Protection with Latch mode (OVP) 230 15% 120 Overload Protection with Latch mode (OLP) The maximum limit of on-time IRIS-W6753 650 85 to 264 58 INTEGRATED SWITCHER Package Outline Description IRIS-W6753 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.
Typical Connection Diagram      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, t...
