Hello,
My team is evaluating the TPS55289EVM, and we are wondering if some of the passive 0402 components can be substituted with 0603 equivalent components. How would this effect the performance of the device?
Thanks,
Hi Andrew,
Thanks for reaching out.
For signal pins like COMP, DITH, EN, and etc, it would be ok to replace with 0603 components.
But for Cin and Cout capacitors, recommend to keep one 0.1uF/0402 capacitor and put them close to Vin-GND and Vout-GND pins to decrease the power loop area.
BRs,
Bryce
