OPERATION DESCRIPTION
GENERAL DESCRIPTION
The LM10000 provides all the circuitry needed to enable most DC/DC regulators to work in a PowerWise®
Adaptive Voltage Scaling (AVS) system. It communicates via the PowerWise Interface (PWI), and has analog
outputs to control the output voltage of a slave power regulator. The slave power regulator can be any device
that sets its output voltage with a feedback resistor divider.
THEORY OF OPERATION
The LM10000 can be thought of as a D/A converter, converting PWI communication to analog outputs. One of
the outputs is a current DAC (IAVS), which is connected to the feedback node of a slave regulator. Therefore, all
PWI Change Voltage Commands (CVC) are decoded into a 7-bit current DAC output. The impedance of the
feedback node at DC appears as the top feedback resistor. This is because the control loop of the slave
regulator effectively maintains a constant current/voltage across the bottom feedback resistor, and creates low
impedance at the VOUT node. Therefore, as more current is sourced into the feedback node, the more the output
voltage is reduced. See Figure 6.
Figure 6. Output Voltage Is Controlled Via current Injection Into Feedback Node
DIGITAL POWER MANAGEMENT
In addition to adaptive voltage scaling, the PWI and LM10000 enhance the slave regulator with basic digital
power management control. This includes control of power states such as SHUTDOWN, SLEEP, and ACTIVE,
ON/OFF sequencing, and voltage scaling slew rate. Figure 7 shows the LM10000 with available system
connectivity options. The LM10000 has a flexible set of logic enable pins to allow the system easy interface to
power states and sequencing. A logic CNTL_EN output is provided to drive the slave regulator enable according
the power state of the LM10000. For example, if a PWI SHUTDOWN command is issued to LM10000, the
CNTL_EN output is immediately driven to 0V, which if connected to the slave regulator enable input, will turn off
the output voltage and enter a low Iq state. A summary of the logic inputs and outputs is given is LOGIC INPUTS
AND OUTPUTS table.
