SLUU224A May 2005 – March 2022 TPS40100
Two TPS40100-EVM can be synchronized to an external clock source of a higher frequency than that of the free running PWM clock. This is a feature that can aid with input filter design. It is recommended that the synchronization frequency be no more than 120% of the free running frequency. The EVM is configured to a switching frequency of 370 kHz, so the external frequency into the synchronization pin should be no more than 470 kHz. Please see Section 5.3.6.
