Hi Team,
My customer is using multiple TPS929120s/board with multiple boards/vehicle and is interested in synchronizing PWMs for PWM dimming.
Could could I get your help/recommendation for a solution in two scenarios:
1. Synchronizing PWMs on a single board:
I have a few ideas for this:
- Just use an external clock source into CLK pin, I think this means we no longer can use that pin as an address pin though so it would need to be set in EEPROM
- If this is the best way, I could use a recommendation if there is a preferred oscillator/clocking part.
- To prevent additional components, we could use a free beacon torch channel and PWM across a resistor, then feed the created PWM signal into the CLK pin of other beacon torches.
2. Synchronizing PWMs across multiple boards
- I could use recommendation, if this is even feasible
Best,
David
