a feedback node/resistors to set the output voltage. configure the voltage step slew rate from the PWI. and 10 kΩ feedback resistors. FIGURE 1. LM10000 Evaluation Board
(output power, input voltage range, etc.). FIGURE 2. Basic Setup
- Install the LM10000 GUI on a PC in close proximity to the LM10000 set up.
- Insure that LM10000 eval board is connected to USB to PWI base board.
- Connect a wire from IAVS to the center of the feedback resistor divider on the slave regulator board.
- Connect a wire from the LM10000 evaluation board ground to the slave regulator board ground.
- Connect a USB cable from a PC to the LM10000 Evaluation board*.
- Apply power to the input of the slave regulator.
- Use the GUI to program IAVS and observe slave regulator voltage scaling on a scope or DMM.
is used, please make sure these two pins are high (push-pull connection on the board).
FIGURE 3. Advanced Setup
- Install the LM10000 GUI on a PC in close proximity to the LM10000 set up.
- Insure that LM10000 eval board is connected to USB to PWI base board.
- Connect a wire from IAVS to the center of the feedback resistor divider on the slave regulator board.
- Connect a wire from CNTL_EN to the enable input of the slave regulator (requires the slave regulator to have a logic enable
- Connect a wire from the LM10000 evaluation board ground to the slave regulator board ground.
- Connect a USB cable from a PC to the LM10000 Evaluation board.*
- Apply power to the input of the slave regulator.
- Use the GUI to program IAVS and power states (active, sleep, shutdown); observe slave regulator voltage on a scope or DMM.
