BOOT2
Channel 2 HS driver supply.
Connect through a capacitor (100nF typ.) to PHASE2 and provide necessary
Bootstrap diode.
A small series resistor upstream the boot diode helps in reducing Boot capacitor
overcharge.
11
UGATE2
Channel 2 HS driver output.
A small series resistors helps in reducing device-dissipated power.
12
PHASE2
Channel 2 HS driver return path.
It must be connected to the HS2 MOSFET source and provides return path for
the HS driver of channel 2.
13
BOOT3
Channel 3 HS driver supply.
Connect through a capacitor (100nF typ.) to PHASE3 and provide necessary
Bootstrap diode.
A small series resistor upstream the boot diode helps in reducing Boot capacitor
overcharge.
14
UGATE3
Channel 3 HS driver output.
A small series resistors helps in reducing device-dissipated power.
15
PHASE3
Channel 3 HS driver return path.
It must be connected to the HS3 MOSFET source and provides return path for
the HS driver of channel 3.
16
SSEND /
PGOOD
SSEND - Intel VR10 Mode.
Soft Start END Signal.
Open Drain Output set free after SS has finished and pulled low when triggering
any protection. Pull up to 5V (typ) or lower, if not used it can be left floating.
PGOOD
- Intel VR9 & AMD Hammer Mode
.
Open Drain Output set free after SS has finished and pulled low when VSEN is
lower than the relative threshold. Pull up to 5V (typ) or lower, if not used it can be
left floating.
17
DAC_SEL
DAC SELection pin.
It allows programming the DAC table for the regulation. Internally pulled-up to 5V.
Short to GND to program VR9 DAC, leave floating to program K8 DAC while
connect to GND through 82k
to program VR10 DAC.
Information about the selected DAC is latched before the system start-up. See
Section 7.1
for connections to enable CPU auto-detection.
18
OSC / EN /
FAULT
OSC
: It allows programming the switching frequency F
SW
of each channel.
Switching frequency can be increased according to the resistor connected from
the pin vs. SGND with a gain of 4kHz/μA (see
Section 14
). Leaving the pin
floating it programs a switching frequency of 100kHz per phase (300kHz on the
load).
EN
: Forced low, the device stops operations with all MOSFETs OFF: all the
protections are disabled except for
Preliminary Over Voltage
. When set low it
resets the device from any latching condition.
FAULT
: The pin is forced high (5V) to signal an OVP / UVP FAULT: to recover
from this condition, cycle VCC or the OSC pin. See
Section 13
for details.
