Hello Team,
Posting on behalf of my customer: (Can TPS1H100 operate for short periods of time at much greater frequency than 2kHz, i.e. 20kHz, without damage?)
Looking at page 9 it shows that the turn-on and turn-off times can vary from 20-50us. Factoring in those times as well as slew rate it clearly isn't going to have typical linear PWM behavior with periods shorter than 500us. So I can understand if the intent is to warn people to stick to 2KHz or slower to have results meet their expectations.
But the other way to read the maximum rating is that very brief periods (50-100us) cause damage that isn't caused by arbitrary duty cycles within a 500us period. Maybe SOA stresses or limitations in the charge pump circuitry? It seems unlikely but I'd like to confirm this.
We are trying to confirm whether the 2KHz/500us absolute maximum rating means that brief exposure to faster PWM, e.g. 50% duty cycle square waves of periods of 50-100us can damage the device.
Thanks!
