The primary contributor to the increase in the junction temperature of the SLG59M1713V is the power dissipation of its power MOSFET. Its power dissipation and the junction temperature in nominal operating mode can be calculated using the following equations: where: PD = Power dissipation, in Watts (W) RDSON = Power MOSFET ON resistance, in Ohms (Ω) IDS = Output current, in Amps (A) and where: TJ = Junction temperature, in Celsius degrees (°C) θJA = Package thermal resistance, in Celsius degrees per Watt (°C/W) TA = Ambient temperature, in Celsius degrees (°C) Figure 3. A SLG59M1713V with CSLEW set to 15nF and 470µF retained for CLOAD. CLOAD-to-CSLEW ratio is smaller than 33,600. Note smooth VOUT transition. PD = RDSON x IDS2 TJ = PD x θJA + TA |
