Software Configuration

1.3 Switches, Jumpers, and LEDs

SW4 controls the main power switch supplying input power to the EVM. After SW4 is enabled, each

separate output supply is turned on and off using individual jumpers. Table 1 shows the jumper

configurations for each supply. Manually enable or disable the supply, depending on the jumper location.

Another option programs the supply with the UCD90120A sequencer. In this mode the UCD90120A is

programmed with the Fusion GUI software. This software controls the turnon times of each supply as well

as monitoring overvoltage and undervoltage conditions.

The LED indication displays which input and output power is enabled or disabled. Table 2 shows which

LEDs correspond to specific supplies onboard.

2 Software Configuration

The Fusion Digital Power Designer software controls the turnon and turnoff of the TSW2200 in sequencer

mode. Download the Fusion software from the Digital Power Software page on the TI Web site. This

software allows configuration of enable control for turning on and turning off the output supplies at specific

time delays. Also available with the Fusion GUI is voltage monitoring of the output. Voltage monitoring

reads out conditions of overvoltage, undervoltage, current, and temperature. The following steps

demonstrate the set up of the Fusion GUI software.
