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. https://elecena.pl/product/25657669/stpm098c-tr-automotive-dual-digital-8-phase-controller-with-pmbus 2024-04-02 https://elecena.pl/product/25657669/stpm098c-tr-automotive-dual-digital-8-phase-controller-with-pmbus 2024-07-07 https://elecena.pl/product/25657669/stpm098c-tr-automotive-dual-digital-8-phase-controller-with-pmbus 2025-03-05 https://elecena.pl/product/25657669/stpm098c-tr-automotive-dual-digital-8-phase-controller-with-pmbus 2025-07-09 https://elecena.pl/product/25657669/stpm098c-tr-automotive-dual-digital-8-phase-controller-with-pmbus 2025-08-05 https://elecena.pl/product/25657669/stpm098c-tr-automotive-dual-digital-8-phase-controller-with-pmbus 2026-03-14 https://elecena.pl/product/25657669/stpm098c-tr-automotive-dual-digital-8-phase-controller-with-pmbus 2026-05-19 https://elecena.pl/product/25657669/stpm098c-tr-automotive-dual-digital-8-phase-controller-with-pmbus 2026-07-15 https://elecena.pl/product/25657669/stpm098c-tr-automotive-dual-digital-8-phase-controller-with-pmbus 2026-08-04
