PIN DESCRIPTION
SVD (Serial VID Data) is a bidirectional signal that is an input and open drain output
for both master (AMD processor) and slave (IR3504), requires an external bias
voltage and should not be floated
System wide Power Good signal and input to the IR3504. When asserted, the
IR3504 output voltage is programmed through the SVID interface protocol.
Connecting this pin to VCCL enables VFIX mode.
Enable input. A logic low applied to this pin puts the IC into fault mode. A logic high
on the pin enables the converter and causes the SVC and SVD input states to be
decoded and stored, determining the 2-bit Boot VID. Do not float this pin as the logic
state will be undefined.
Output 2 average current input from the output 2 phase IC(s). This pin is also used
to communicate over voltage condition to the output 2 phase ICs.
Programs output 2 startup and over current protection delay timing. Connect an
external capacitor to LGND to program.
Output 2 reference voltage programmed by the SVID inputs and error amplifier non-
inverting input. Connect an external RC network to LGND to program dynamic VID
slew rate and provide compensation for the internal buffer amplifier.
Programs the output 2 constant converter output current limit and hiccup over-
current threshold through an external resistor tied to VDAC2 and an internal current
source from this pin. Over-current protection can be disabled by connecting a
resistor from this pin to VDAC2 to program the threshold higher than the possible
signal into the IIN2 pin from the phase ICs but no greater than 5V (do not float this
pin as improper operation will occur).
