Power Dissipation (Note 1) ................................. 600 mW
TK6593x ELECTRICAL CHARACTERISTICS
V
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
Note 3: When using test circuit below.
Note 4: Refer to Page 5 graph of Peak Current Threshold vs. Supply Voltage.
Gen. Note: Refer to “INDUCTOR VALUE SELECTION” and “INDUCTOR TYPE SELECTION” of Design Considerations Section for choosing
