4.4 Thermal Information

TJ = 25°C (unless otherwise stated)
THERMAL METRIC MIN TYP MAX UNIT
RθJA Junction-to-ambient thermal resistance (min Cu)(2) 125 °C/W
Junction-to-ambient thermal resistance (max Cu)(2)(1) 50
RθJC Junction-to-case thermal resistance (top of package)(2) 2.1 °C/W
Junction-to-case thermal resistance (VIN pin)(2) 1.1
(1) Device mounted on FR4 material with 1in2 (6.45cm2) Cu.
(2) RθJC is determined with the device mounted on a 1in2 (6.45cm2), 2oz (0.071mm) thick Cu pad on a 1.5in × 1.5in
(3.81cm × 3.81cm), 0.06in (1.52mm) thick FR4 board. RθJC is specified by design while RθJA is determined by the user’s board design.
