TPS4100 – KL/Rev. 2.5/02.05

Note 6: Minimum and maximum limits are guaranteed but may not be 100% tested.

shown are applicable only when the TPS4100 is used in conjunction with the TCD6001 Class-T

Controller. See Application/Test Circuit of TCD6001 data sheet for additional information.

Bandwidth = 20kHz. See Application/Test Circuit.

.

Note 7: The TPS4100 heat sinking in AM Mode must be increased (as compared to Class-T mode) to sustain the

typical output numbers. This is due to the lower efficiency of Class B output stage operation.
