STMicroelectronics STPM098C-TR Power Switch IC 48-Pin, VFQFN 48+4L

The STMicroelectronics Automotive dual digital 8 phase 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 or drop for efficiency enhancement for light load range.
