3 / 19 page www.ti.com ABSOLUTE MAXIMUM RATINGS (1) RECOMMENDED OPERATING CONDITIONS TL594 PULSE-WIDTH-MODULATION CONTROL CIRCUIT SLVS052G – APRIL 1988 – REVISED JANUARY 2007 over operating free-air temperature range (unless otherwise noted) VALUE UNIT VCC Supply voltage(2) 41 V Amplifier input voltage VCC + 0.3 V Collector output voltage 41 V Collector output current 250 mA D package 73 N package 67 θ JA Package thermal impedance(3)(4) °C/W NS package 64 PW package 108 TJ Operating virtual junction temperature 150 °C Tstg Storage temperature range –65 to 150 °C (1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values, except differential voltages, are with respect to the network ground terminal. (3) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. (4) The package thermal impedance is calculated in accordance with JESD 51-7.
