Product Description

The UCD9248PFC is a multi-rail multi-phase synchronous buck digital Pulse Width Modulation (PWM) Controller designed for non-isolated DC/DC power applications. This device integrates dedicated circuitry for DC/DC loop management with flash memory and a serial interface to support configurability, monitoring and management. It is designed to provide a wide variety of desirable features for non-isolated DC/DC converter applications while minimizing the total system component count by reducing external circuits. The solution integrates multi-loop management with sequencing, margining, tracking and intelligent phase management to optimize for total system efficiency. Additionally, loop compensation and calibration are supported without the need to add external components. To facilitate configuring the device, the Texas Instruments Fusion Digital Power™ Designer is provided. This PC based Graphical User Interface offers an intuitive interface to the device.
Up to 1mV closed loop resolution
Supports multiple soft-start and soft-stop configurations including prebias start-up
Supports voltage tracking, margining and sequencing
Supports current and temperature balancing for multi-phase power stages
