These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. PACKAGE BOARD θ JC θ JCB θ JA PowerFLEX (KTP) High K, JESD 51-5 3 °C/W 28 °C/W SOT-223 (DCY) High K, JESD 51-7 30.6 °C/W 53 °C/W TO-252 (KVU) High K, JESD 51-5 30.3 °C/W (1) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.

(2) Line voltage regulation is expressed here as the percentage change in output voltage per 1-V change at the input. (3) CADJ is connected between the ADJUST terminal and ground. 2 Submit Documentation Feedback |
