AEC-Q100 triple buck for automotive power trees
The Texas Instruments TPS65263-1QRHBRQ1 is an automotive-grade (AEC-Q100) triple-output synchronous buck converter in a 32-VFQFN exposed-pad package. It delivers one 3A rail and two 2A rails from a single 4V to 18V input, covering the typical automotive battery range from cold-crank through load-dump. Synchronous rectification is integrated, so no external catch diode is needed.
Output rails: 3A primary, 2A auxiliary
The three outputs are independently programmable from a minimum of 0.68V up to 6.3V. The 3A channel is typically used for the core SoC or processor rail; the two 2A channels handle I/O or memory supplies. Output configuration is positive, and the regulator uses a buck topology.
Cut-tape quantities are also available for prototyping.
