Pin functions (continued)
Internal DAC reference output. Bypass to GND with a 10nF capacitor.
Current monitor output. Bypass to remote ground through R- C network.
Current Monitor gain setting pin. Connect to VOUT through a resistor in the
range 0.47 kΩ to 7 kΩ.
Soft-start programming pin and mode of operation selection input.
Current limit input. Connect ILIM to GND with a resistor to set the current limit
threshold.
Frequency selection pin. Connect this pin to the input power supply rail
through a resistor.
Power good signal (open drain output). High when VCC_GFX output voltage is
within +200mV/-300mV of the programmed VDAC value.
Render suspend state enter and render suspend exit mode control input. pulse
skipping or forced PWM working mode selection for IMVP6.5 CPU and VR11
mode.
Power ground.
Low side gate driver output.
+5V supply for internal driver supply.
CLOCK ENABLE open-drain output (active low) and mode of operation
selection pin.
Bootstrap capacitor connection. Input for the supply voltage of the high side
gate driver.
High side gate driver output.
Switch node connection and return path for the high side gate driver.
Switching regulator ON/OFF control input.
VIDs bits of the controller voltage programming DAC input. They allow
programming the no-load output voltage, depending on the selected mode of
operation. VID0 is the LSB and VID6 the MSB. Connect VIDx to a voltage
<0.33V to program a ‘0’; connect VIDx to a voltage >0.77V to program a ‘1’.
Exposed pad. Connect to SGND.
