Five-channel PMIC for OMAP power trees
The TPS65073RSLT is a 5-channel power-management IC from Texas Instruments, integrating two LDOs alongside the main converters, tailored for Mobile/OMAP applications. Its input range of 2.8V to 6.3V covers single-cell Li-Ion through 5V USB, which is the core fit question for mobile/OMAP designs. The 5-channel integration reduces BOM count and board area, critical for space-constrained handheld devices.
Package and thermal land pattern
Housed in a 48-VFQFN with an exposed pad, the package demands a proper thermal land pattern on the PCB — without it the 5-channel power dissipation can exceed the package's ability to shed heat. The supplier device package is 48-VQFN (6x6), and mounting is surface mount.
The base product number is TPS65073.
