DESCRIPTION

•

Supports Multiple Soft-Start and Soft-Stop

Configurations Including Prebias Start-up

The UCD9224 is

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

Supports Voltage Tracking, Margining and

Sequencing

Supports Current and Temperature Balancing

for Multi-Phase Power Stages

support

configurability,

monitoring

and

management.

Supports Phase Adding/Shedding for

Multi-Phase Power Stages

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

Sync In/Out Pins Align DPWM Clocks Between

Multiple UCD92xx Devices

12-Bit Digital Monitoring of Power Supply

Parameters Including:

circuits.

The

solution

integrates

multi-loop

management with sequencing, margining, tracking

and intelligent phase management to optimize for

–

Input/Output Current and Voltage

Temperature at Each Power Stage

total

system

efficiency.

Additionally,

loop

compensation and calibration are supported without

the need to add external components.

•

Multiple Levels of Over-current Fault

Protection:

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.

–

External Current Fault Inputs

Analog Comparators Monitor Current

Sense Voltage

–

Current Continually Digitally Monitored

•

Over- and Under-voltage Fault Protection

Over-temperature Fault Protection

Enhanced Nonvolatile Memory with Error

Correction Code (ECC)

TI has also developed multiple complementary power

stage solutions – from discrete drivers in the UCD7k

family to fully tested power train modules in the PTD

family. These solutions have been developed to

complement the UCD9k family of system power

controllers.

•

Device Operates From a Single Supply with an

Internal Regulator Controller That Allows

Operation Over a Wide Supply Voltage Range

Supported by Fusion Digital Power™

Designer, a Full Featured PC Based Design
