Manufacturer:UC Description:A simple experiment will determine whether the actual circuit board layout is adequate (i.e., BA is low enough) so that the maximum recommended junction temperature of the UC3846J will not be exceeded. The procedure uses the internal thermal shutdown feature of the UC3846J (at TJ 175C) to deter- mine when the junction is approximately 50C above the maximum recommended junction temperature (TJ = 125C). Operate the circuit with normal or other desired test electrical conditions. Increase the ambient temperature and determine the value at which thermal limit occurs (by sensing a sudden drop in VREG output). At this point TJ is approximately 175C. If this occurs at an ambient temperature of more than 50C above the system ambient temperature design goal, the TJ will not exceed 125C under the same electrical conditions when the ambient temperature is at the system design goal value. |
