製品概要
概要
STPM098C is a dual-loop digital multi-phase buck controller with built-in NVM and PMBus™ interface for automotive applications.
The product finds application in the power management of loads that require high power, such as cores of processors and memories. It controls up to 8 external drivers+MOS and, with its two loops, allows to supply up to two different voltages.
An advanced control loop architecture based on COT (constant on-time) scheme provides fast transient responses and high efficiency. The device also provides phase interleaving and dynamic phase add/drop for efficiency enhancement for light load range.
STPM098C supports a ver.1.2 compliant PMBus™ communication with 8 possible interface address values for reporting the telemetry of voltage, current, power, temperature and fault signaling.
The device programmable parameters can be configured through the PMBus™ interface and stored in an on-chip NVM minimizing external components.
STPM098C additionally provides an extensive monitoring unit system and fault protection including independent UV/OV on output voltage, loop feedback disconnection, phase current unbalancing and dual-threshold overcurrent for both positive and negative phase currents.
