Hi,

Customers use TPS in fixed PWM mode.
Can the sync pin be connected directly to VIN?
Is pull-up resistor required?

Best Regards,

Hi Yusuke-san,

Yes, this is written on page 3 of the D/S and done this way in the EVM.

As well, this is an old device. TPS62147/8 would be recommend for wider Vin range, smaller size, etc.
