Recommended Operating Conditions are conditions under which the device operates correctly. Recommended Operating Conditions do not imply guaranteed performance limits. Note 2: Maximum allowable DC power dissipation is a function of the maximum junction temperature, TJMAX , the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: The junction-to-ambient thermal resistance, θJA, for LM2636 in the M20B package is 88˚C/W, and 120˚C/W for the MTC20 package. www.national.com 5 |
