SLVU347 – December 2009 Evaluation Module for UCD90120 and UCD90124 This User’s Guide describes the evaluation modules (EVM) for the UCD90120 (UCD90120EVM) and UCD90124 (UCD90124EVM). The EVM contains evaluation and reference circuitry for the UCD90120 and UCD90124. UCD90120 and UCD90124 are advanced power system controllers containing sequencing, monitoring, fan control and many other power supply system support features. -
Page 2: Contents 1 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. -
Page 3: Quick Start
Test Setup Figure 1 shows a typical test setup for UCD90120/4EVM. All that is required is a 12V (500mA for UCD90120EVM or 2000mA for UCD90124EVM running a fan) wall adapter/laptop power supply (see J1 BOM description for receptacle size) and a PC. The USB-EVM cable is provided with the EVM. -
