The Texas Instruments UCD9248PFC is a digital PWM system controller designed for high-performance power management applications. This device controls up to 4 voltage rails and 8 phases, supporting switching frequencies up to 2MHz with a precise 250 ps duty-cycle resolution and 1mV closed-loop resolution.
Key features include hardware-accelerated compensation, multiple soft-start and soft-stop configurations, voltage tracking, margining, and sequencing. It also supports current and temperature balancing for multi-phase power stages, along with phase adding/shedding. The UCD9248PFC includes 12-bit digital monitoring of power supply parameters and multiple levels of over-current, over-voltage, and over-temperature fault protection.
Packaged in an 80-TQFP, this controller operates within a temperature range of -40°C to 125°C. It is suitable for specialized power management applications requiring precise digital control and monitoring capabilities. The device is supported by the Fusion Digital Power Designer tool for simulation, configuration, and monitoring.
