Hello Team,

We've found new opportunity of TRS3223-Q1 in BMW RSE silver box.

Could I ask schematic review for the customer's 1st draft as attached?

Thank you in advance.

TRS3223-Q1 IC5006
Checked	Status (Good, bad, okay, ?)	Additional comments
Schematic pinout matches datasheet pinout	Good
Local decoupling cap on Vcc	Good
Switching caps sized correctly	Bad	Refer to table 6 in the datasheet. Current schematic is using 0.47uF for all values. Cap on C1 should be 0.1uF, other caps should also be 0.1uF if Vcc will always be 3.3V
Input pins are properly biased	Good
