TPS40200-Q1 How to sync clock between two TPS40200

Other Parts Discussed in Thread: TPS40200

I need to sync clock between two TPS40200 to avoid sub harmonic, one VOUT is 3V3 (Master, source clock from RC circuit) and one VOUT is 1V8 (slave). Typical current is 50mA and 200mA respectively.

How this is done that work to high temperature (150C)?.

Thanks

The recommended operating temperature of TPS40200 is only up to 125c.

Not sure if there is any problem when temp is 150c.

thanks

I don't think two TPS40200 devices can sync each other with no external signal.
It might need an external signal to sync both devices.

The sync applicaiton information can be found on datasheet page 13.

Thanks
