| Data Sheet No. PD 96945A IRIS-G6351S Features * 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. * Low start-up circuit current (50uA 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. * No VDSS de-rating is required. * Built-in constant voltage drive circuit * Various kinds of protection functions * Pulse-by-pulse Overcurrent Protection (OCP) * Overvoltage Protection with latch mode (OVP) * Thermal Shutdown with latch mode (TSD) IRIS-G6351S 650 3.95 INTEGRATED SWITCHER Package Outline TO-220 Fullpack (5 Lead) Key Specifications Type MOSFET VDSS(V) RDS(ON) MAX AC input(V) 23015% 85 to 264 Pout(W) Note 1 65 30 Descriptions Note 1: The Pout (W) represents the thermal rating at PRC Operation, and the peak power output is obtained by approximately 120 to 140% of the above listed. When the output voltage is low and ON-duty is narrow, the Pout (W) shall become lower than that of above. IRIS-G6351S is a hybrid IC consists from power MOSFET and a controller IC, designed for PRC fly-back converter type SMPS (Switching Mode Power Supply) applications. This IC realizes 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). Typical Connection Diagram IRIS-G6300 OCP/FB Vin GND S D www.irf.com IRIS-G6351S 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.

Fig.1 V2-3 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. www.irf.com IRIS-G6351S Electrical Characteristics (for Control IC) Electrical characteristics for control part (Ta=25, Vin=20V,unless otherwise specified) Symbol Vin(ON) Vin(OFF) Iin(ON) Iin(OFF) TOFF(MAX) Vth IOCP/FB Vin(OVP) Iin(H) Vin(La.OFF) Tj(TSD) Definition Operation start voltage Operation stop voltage *6 Circuit current in operation Circuit current in non-operation Maximum OFF time O.C.P/F.B Pin threshold voltage O.C.P/F.B Pin extraction current O.V.P operation voltage Latch circuit sustaining current *7 Latch circuit release voltage *6,7 Thermal shutdown operating temperature MIN 15.8 9.1 12 0.7 0.7 23.2 7.9 135 Ratings TYP 17.6 10.1 15 0.76 0.8 25.5 - MAX 19.4 11.1 5 50 18 0.82 0.9 27.8 70 10.5 - Units V V mA A sec V mA V A V Test Conditions Vin=019.4V Vin=19.49.1V Vin=15V Vin=027.8V Vin=27.8(Vin(OFF)-0.3)V Vin=27.87.9V - *6 The relation of VIN(OFF) >VIN(La.OFF) is applied for each product *7 The latch circuit means a circuit operated O.V.P and T.S.D.
