SLVSEW9B August 2019 – December 2019 TPS66120 , TPS66121
PRODUCTION DATA.
The TPS6612x is a fully featured integrated Sink power path with a high voltage VBUS LDO voltage regulator. The Sink power path can support up to 5 A at 20 V controlled by a general-purpose I/O. The Sink power path includes soft-start to minimize in-rush currents, overtemperature protection, reverse-current protection, undervoltage protection, and an optional overvoltage protection configured in the application. See the 20-V Sink (PPHV Power Path) section.
The VBUS low dropout voltage regulator may be used in systems that require power during dead battery conditions and can provide up to 30 mA to the system via the VLDO pin. Once VIN power is available, VLDO pin power is switched from the VBUS LDO regulator to the VIN pin. The TPS66120 devices VBUS LDO regulator nominally supplies 3.3 V where the TPS66121 device VBUS LDO regulator nominally supplies 5 V. See the Power Management and Supervisory section.
