Functional Pin Description
VCC (Pin 1)
Provide a 12V bias supply for the IC to this pin. This
pin also provides the gate bias charge for all the
MOSFETs controlled by the IC. The voltage at this
pin is monitored for Power-On Reset (POR) purposes.
DRIVE2 (Pin 2)
Connect this pin to the gate of an external MOSFET.
This pin provides the drive for the NVVDD regulator’s
pass transistor.
of DACOUT sets the VTT converter output voltage,
as well as the corresponding PGOOD and OVP
thresholds.
PGOOD (Pin 8)
PGOOD is an open collector output used to indicate
the status of the output voltages. This pin is pulled
low when the synchronous regulator output is not
within ±10% of the DACOUT reference voltage or
when any of the other outputs are below their under-
voltage thresholds.
VID2, VID1, VID0 (Pins 5, 6 and 7)
VSEN2 (Pin 9)
VID0-2 are the TTL-compatible input pins to the 3-bit
DAC. The logic states of these three pins program
the internal voltage reference (DACOUT). The level
Connect this pin to a resistor divider to set the linear
regulator (NVVDD) output voltage.
