Good morning -
We’re looking for a small switching supply to make a 5V rail on our board (vs linear solutions such as using the LM317). We found the following 3x3 QFN pkg parts:
TPS62130A – 3A @ 2.5MHz
TPS62150A – 1A @ 3Mhz
Both of these meet our requirements of <1A. It looks like both parts datasheets were originally released November 2011, and the datasheets were updated June 2013. Does TI have a recommendation on using one part over the other? Does one have a longer support life than the other? We are looking in the realm of 5-7 years.
Regards,
Thomas
