I am just after some advice please. I require a Texas Instruments TPS63001DRCR buck boost converter for a project. I am trying to source one locally at a better price and have located a TPS63001DRCT. I have looked at the data sheet for that series of parts but I am at a lose to determine the difference between the two parts. Can anyone please shed some light on the difference/s and tell me how I can approach this problem in the future. Thanks in advance
