Description
The TPS62102EVM–01 evaluation module is supplied fully assembled and ready to test. This
evaluation module demonstrates an automatic mode switching converter that is capable of
500-mA output current at 3.3 V. The switching frequency of this converter is 1 MHz free running.
Other versions of this converter IC are available that have nominal switching frequencies of 300
kHz, 600 kHz, and 2 MHz. Note that the fundamental frequencies have been chosen to minimize
interaction with 455-kHz intermediate frequency (IF) circuits. The user needs to supply a power
source and suitable load. Figure 1 is the schematic of the evaluation module as assembled. In
this configuration, the converter should have a closed-loop bandwidth of approximately 40 kHz.
