| Data Sheet No. PD 96952A IRIS-W6754 Features * 6-pin SIP type full molded package, optimum IC for low-height SMPS, distance between high and low voltage pins is 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% 160 Overload Protection with Latch mode (OLP) IRIS-W6754 650 85 to 264 100 The maximum limit of on-time 0.96 INTEGRATED SWITCHER Package Outline Description IRIS-W6754 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 IRIS-W6754 O CP / BD FB SS / O LP Vcc S/ G ND D 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. www.irf.com IRIS-W6754 Absolute Maximum Ratings (Ta=25C) 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. Terminal s Max.
