Q: TPS61201EVM-179 resistor size by 1621419

 

1) Does the EVM comes with a 0603 resistor already soldered in place for R4?

 

2) We state in the bill of material of the EVM user guide that the size of  those resistors should be 0603. He is having trouble finding such size in Canada.  Can he uses other sizes?  He wanted to know again how easy to remove those resistors from the adjustable EVM.

1) There are 3 dash numbers for the TPS6120xEVM-179.  The customer can see which dash number he ordered and received by looking at the label on the ESD bag and/or on the PCB.  The BOM on page 8 of the user's guide states what value has been installed for R4.  R4 is always installed on each version, but on the -002 and -003 (fixed versions) it is a 0Ohm as required.

2) Yes, all the resistors are 0603 sized as this is the most common size used and is large enough to work with.  He should be able order these from any vendor (digikey, etc).  He can use other sized resistors but may have trouble fitting them on the pads.

If the customer wants to evaluate the TPS61201, they should order the TPS61021EVM-179 (HPA179-002).
