IRIS-G5653 Features INTEGRATED SWITCHER • 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. Package Outline • Low start-up circuit current (100uA 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 • Built-in step drive circuit • Built-in low frequency PRC mode (≒20kHz) • Various kinds of protection functions • Pulse-by-pulse Overcurrent Protection (OCP) • Overvoltage Protection with latch mode (OVP) TO-220 Fullpack (5 Lead) Key Specifications Type MOSFET VDSS(V) RDS(ON) MAX • Thermal Shutdown with latch mode (TSD) IRIS-G5653 Descriptions 650 1.9Ω AC input(V) Pout(W) Note 1 230±15% 125 85 to 264 60 IRIS-G5653A is a hybrid IC consists from power MOSFET and a controller IC, designed for Indirect feed-back QuasiResonant (including low frequency PRC) 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 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-G5600 OCP/FB Vin GND S D www.irf.com IRIS-G5653A 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.

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-G5653A Electrical Characteristics (for Control IC) Electrical characteristics for control part (Ta=25℃, Vin=18V,unless otherwise specified) Symbol Vin(ON) Vin(OFF) Iin(ON) Iin(OFF) TOFF(MAX) Tth(2) TOFF(MIN) Vth(1) Vth(2) IOCP/FB Vin(OVP) Iin(H) Vin(La.OFF) Tj(TSD) Vin(SENSE) - Definition Operation start voltage Operation stop voltage Circuit current in operation Circuit current in non-operation Maximum OFF time Minimum time for input of quasi resonant signals *6 Minimum OFF time *7 O.C.P/F.B Pin threshold voltage 1 O.C.P/F.B Pin threshold voltage 2 O.C.P/F.B Pin extraction current O.V.P operation voltage Latch circuit sustaining current *8 Latch circuit release voltage *8 Thermal shutdown operating temperature Detected Voltage Temperature coefficient of detected voltage MIN 14.4 9 45 Ratings TYP 16 10 - MAX 17.6 11 20 100 55 Units V V mA µA µsec 0.68 1.3 1.2 34 6.6 140 31.7 - 0.73 1.45 1.35 36.5 32 2.5 1 2 0.78 1.6 1.5 39 400 8.4 32.3 - µsec µsec V V mA V µA V ℃ V mV/℃ Test Conditions Vin=0→17.6V Vin=17.6→9V Vin=14V Vin=0→39.0V Vin=39.0→8.5V Vin=39.0→6.6V Vin=31.7→32.3V Vin=31.7→32.3V *6 Recommended operating conditions Tth(2)≧1.0μsec Time for iunput of quasi resonant signals ＶO.C.P/F.B For the quasi resonant signal inputted to OCP/FB Pin Vth(2) at the time of quasi resonant operation, the signal shall 0V be wider thant Tth(2). *7 The minimum OFF time means TOFF width at the time when the minimum quasi resonant signal is inputted. *8 The latch circuit means a circuit operated O.V.P and T.S.D.
