Texas Instruments LM10000
The LM10000 is used to enable Adaptive Voltage Scaling (AVS) to non-AVS regulators. It includes a complete Slave Power Controller (SPC 2.0) to communicate to the PowerWise™ Interface (PWI 2.0), and a programmable current output DAC that allows voltage control to any regulator utilizing a feedback node/resistors to set the output voltage. In addition to enabling AVS the LM10000 allows the system to control power states such as sleep and shutdown, and to configure the voltage step slew rate from the PWI.| Part No. | LM10000 |
