The adjustable output sits between 1.2 V and 5.5 V, and the synchronous rectifier keeps efficiency high across the load range. The 14-VSON (4x3) package with exposed pad sinks heat into the PCB copper pour.
The 2.4 MHz switching frequency lets the designer use small inductors and ceramic caps, shrinking the total solution area on a dense automotive PCB.
Yes, it is listed under the Automotive, AEC-Q100 series, meaning it has passed the AEC-Q100 stress tests for automotive-grade ICs.
It switches at 2.4 MHz, which allows the use of small external inductors and capacitors to save board space.
The base product number is TPS63020, and the Q suffix indicates automotive qualification. It is a drop-in replacement where the commercial part was used, provided the wider temperature range and automotive-grade screening are acceptable for the application.
