Description
The UCD90SEQ48EVM-560 allows the Texas Instruments UCD9090 48-pin sequencer to be installed into
the onboard socket for evaluation. Access to all of the user input/output (I/O) is provided via strip
connectors for integration into complex systems using clip-type jumper wires.
This development board also allows direct PMBus (power management bus) communication with the
sequencer via an onboard USB interface. This interface allows direct control of and feedback from the
sequencer when using the TI Fusion Digital Power Designer graphical user interface (GUI).

Quick Start
Test Setup
Figure 1 shows a typical test setup for the UCD90SEQ48EVM-560. All that is required is a personal
computer (PC) with a USB port and the TI Fusion Digital Power Designer GUI. The USB-EVM cable is
provided with the evaluation module (EVM) and is used for EVM power.
When installing the UCD9090 sequence devices into XU1, ensure that the device pin 1 is oriented as
shown in Figure 1 .
