PIN DESCRIPTION
VID inputs for Output 1
Enable input. A logic low applied to this pin puts output 2 into fault mode. A
logic high signal on this pin enables output 2. Do not float as the logic state will
be undefined.
Enable input. A logic low applied to this pin puts output 2 into fault mode. A
logic high signal on this pin enables output 2. Do not float 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. Connect an external RC network to LGND to
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 IIN pin from the phase ICs but no greater than
5V (do not float this pin as improper operation will occur).
