The UCD9248PFCR from Texas Instruments is a highly configurable digital PWM system controller. It is designed to manage multiple voltage rails and phases in non-isolated DC/DC converters, supporting up to 4 voltage rails and 8 phases.
This controller operates with switching frequencies up to 2MHz, providing a duty-cycle resolution of 250 ps and a closed-loop resolution of up to 1mV. It features hardware-accelerated compensation for improved transient performance and supports various soft-start, soft-stop, voltage tracking, margining, and sequencing configurations. The device also includes capabilities for current and temperature balancing, as well as phase adding/shedding for multi-phase power stages.
Key electrical specifications include an operating voltage range of 3V to 3.6V and an operating temperature range of -40°C to 125°C. The UCD9248PFCR is housed in an 80-TQFP package, suitable for surface mount applications.
This controller is supported by the Fusion Digital Power Designer tool, which aids in simulating, configuring, and monitoring power supply performance. It is ideal for applications requiring precise digital control over complex power delivery systems.
