Description
The UCD90120 and UCD90124 EVM provides many sophisticated power supply system controller
application capabilities. The EVM allows direct PMBus (power management bus) communication with the
UCD90120 and UCD90124 via an onboard USB interface. This interface allows direct control and
feedback with the UCD90120 and UCD90124 when using the
TI-Fusion-Digital-Power-Designer-Graphical-User-Interface.
