2 / 20 page Page 2 May 2000 TOKO, Inc. TK6592x Note 1: Power dissipation is 600 mW when mounted as recommended (200 mW In Free Air). Derate at 4.8 mW/ °C for operation above 25 °C. Note 2: Converter supply current is dependent upon the DC resistance of inductor L 1. Lower DC resistances will result in lower supply currents. Note 3: When using test circuit below. Gen. Note: Refer to “INDUCTOR VALUE SELECTION” and “INDUCTOR TYPE SELECTION” of Design Considerations Section for choosing inductor.
