(2) The package thermal impedance is calculated in accordance with JESD 51-7 standard with a 4-layer board and 1 W power dissipation. (3) RθJA is highly related to PCB layout and heat sinking. See Figure 107 for measured RθJA vs PCB area from a 2-layer board and a 4- layer board. 6.4 Thermal Information THERMAL METRIC(1)(2) LM43600 UNIT PWP (HTSSOP) 16 PINS RθJA Junction-to-ambient thermal resistance 39.9(3) °C/W RθJC(top) Junction-to-case (top) thermal resistance 26.9 °C/W RθJB Junction-to-board thermal resistance 21.7 °C/W ψJT Junction-to-top characterization parameter 0.8 °C/W ψJB Junction-to-board characterization parameter 21.5 °C/W RθJC(bot) Junction-to-case (bottom) thermal resistance 2.3 °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. Unless otherwise stated, the following conditions apply: VIN = 12 V, VOUT = 3.3 V, FS = 500 kHz.
