Absolute maximum ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions for which the device is intended to be functional. 2). The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to- ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD (MAX) = (TJ (MAX) – TA) θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. 3). All limits guaranteed at room temperature (standard typeface) and at temperature extremes (bold typeface). 4). Typical numbers are at 25°C and represent the most likely norm. 5). Current limit at 0% duty cycle. |
