Description The PWR091EVM is designed as a dual-output converter. It uses a nominal 12-V bus to produce a regulated 1.2-V output at up to 20 A of load current, and a regulated 3.3-V output at up to 15 A of load current.
The Fusion Digital Power Designer is the graphical user interface (GUI) used to configure and monitor the Texas Instruments TPS40422 power controller on this evaluation module. The application uses the PMBus protocol to communicate with the controller over serial bus by way of a TI USB adapter (see Figure 4.1.2...
Control Loop Gain and Phase Measurement Procedure The PWR091EVM includes a 49.9-Ω series resistor in the feedback loop for both Vout1 and Vout2. These resistors are used for loop response analysis and are accessible at the test points TP8 and TP9 for Vout1, and TP10 and TP12 for Vout2.
