Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if
the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc)
Note 1: The switch pin voltage (VLX) doesn’t include the peak voltage generated by TCV7104FN’s switching.
A negative voltage generated in dead time is permitted among the switch pin current (ILX).

Note 3: The TCV7104FN may into thermal shutdown at the rated maximum junction temperature. Thermal design is
required to ensure that the rated maximum operating junction temperature, Tjopr, will not be exceeded.
