The Texas Instruments TPS53681RSBT is a versatile dual-channel D-CAP+ multiphase step-down controller designed for efficient power management applications. It supports phase configurations from a minimum of 1-Phase + 1-Phase up to a maximum of 6-Phase + 2-Phase or 5-Phase + 3-Phase, offering flexibility for various power requirements.
This controller operates within an input voltage range of 4.5V to 17V and provides a programmable frequency control from 300 kHz to 1 MHz. Key features include an 8-bit DAC with selectable resolution and output ranges, driverless configuration for high-frequency switching, and dynamic output voltage transitions via PMBus. It also incorporates programmable internal loop compensations and non-volatile memory (NVM) for reduced external component counts.
The TPS53681RSBT is housed in a 40-WQFN exposed pad package and is designed for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ). The controller supports individual phase current calibrations and reports, along with dynamic phase shedding for optimizing efficiency at light and heavy loads. Fast phase-adding is included for undershoot reduction.
