1.3 Specification

The TPS7H6101EVM has the following ratings.

Table 1-1 EVM Rating Specifications
Name Test Points/Connectors TPS7H6101EVM
PVIN J13 0-100 V
DVIN J1 0-14 V
PWM_LI Pin 1 of J9 0-14 V
EN_HI Pin 4 of J9 0-14 V
Temperature N/A 25 C
PWM_LI Frequency N/A 100kHz
PWM_LI Duty Cycle N/A 28%

The following connections are used to switch between different input connectors for the input waveform.

EN_HIBP5LJ4

The frequency of the boards has been optimized to 100kHz. While other frequencies can be used, special care must be taken that the TPS7H6101-SEP and L1 do not overheat.

The following edits have to be made to switch between PWM mode and IIM mode.
