(2) Determine power rating at a specific ambient temperature TA with a maximum junction temperature (TJ) of 125°C (see Recommended Operating Conditions ). 6.4 Thermal Information THERMAL METRIC(1)(2) LMR23615 UNIT DRR (WSON) (12 PINS) RθJA Junction-to-ambient thermal resistance 41.5 °C/W ψJT Junction-to-top characterization parameter 0.3 °C/W ψJB Junction-to-board characterization parameter 16.5 °C/W RθJC(top) Junction-to-case (top) thermal resistance 39.1 °C/W RθJC(bot) Junction-to-case (bottom) thermal resistance 3.4 °C/W RθJB Junction-to-board thermal resistance 16.3 °C/W 6.5 Electrical Characteristics Limits apply over the recommended operating junction temperature (TJ) range of –40°C to +125°C, unless otherwise stated. Minimum and Maximum limits are specified through test, design or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only.
