Description
General part information
UCD9224 Series
The UCD9224 is a multi-rail, multi-phase synchronous buck digital 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.
The UCD9224 was 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. This tool allows the design engineer to configure the system operating parameters for the application, store the configuration to on-chip non-volatile memory and observe both frequency domain and time domain simulations for each of the power stage outputs.
