PIU
SW1, SW2, SW3 (Pins 30, 27, 21):
Switch Node Connec-
tions to Inductors. Voltage swing at these pins is from a
Schottky diode (external) voltage drop below ground to
V
IN
(where V
IN
is the external MOSFET supply rail).
TG1, TG2, TG3 (Pins 31, 28, 20):
High Current Gate Drives
for Top N-Channel MOSFETs. These are the outputs of the
floating drivers with a voltage swing equal to the boost
voltage source superimposed on the switch node voltage
SW.
BOOST1, BOOST2, BOOST3 (Pins 32, 29, 19):
Positive
Supply Pins to the Topside Floating Drivers. Bootstrapped
capacitors, charged with external Schottky diodes and a
boost voltage source are connected between the BOOST and
SW pins. Voltage swing at the BOOST pins is from the boost
source voltage (typically V
CC
) to this boost source voltage
+V
IN
(where V
IN
is the external MOSFET supply rail).
PGOOD (Pin 33):
This open-drain output is pulled low
when the output voltage is outside the PGOOD tolerance
window. PGOOD is blanked during VID transitions for
approximately 100
μ
s.
VID0, VID1, VID2, VID3, VID4, VID5 (Pins 35, 36, 37, 17,
18, 34):
Output Voltage Programming Input Pins. When
VID5 is tied to V
CC
, the Intel VRM9 VID table is selected.
When voltage of VID5 is less than V
CC
– 2V, VID5 serves
as the fifth VID bit of VRM10.
OUTEN (Pin 38):
On/Off Control of the Controller.
SGND (Pin 39, Exposed Pad):
Signal Ground. This pin
must be soldered to the ground plane.
