4-Phase Controller with On Board Gate Drivers for CPU Applications

NCP5395
Product Preview
2/3/4-Phase Controller with
On Board Gate Drivers for
CPU Applications
The NCP5395 provides up to a four−phase buck solution which
combines differential voltage sensing, differential phase current
sensing, adaptive voltage positioning, and on board gate drivers.
Dual−edge pulse−width modulation (PWM) combined with inductor
current sensing reduces system cost by providing the fastest initial
response to dynamic load events. Dual−edge multiphase modulation
reduces the total bulk and ceramic output capacitance required to meet
transient regulation specifications.
The on board gate drivers includes adaptive non overlap and power
saving operation. A high performance operational error amplifier is
provided to simplify compensation of the system. Patented Dynamic
Reference Injection further simplifies loop compensation by
eliminating the need to compromise between closed−loop transient
response and Dynamic VID performance.

FUNCTIONAL DESCRIPTIONS
General
voltage with the DAC voltage. The non−inverting input
sums the remote output voltage with a 1.3 V reference. The
resulting voltage at the output of the remote sense amplifier is:
The NCP5395 dual edge modulated multiphase PWM
controller is specifically designed with the necessary
features for a high current CPU system. The IC consists of
the following blocks: Precision Flexible DAC, Differential
Remote Voltage Sense Amplifier, High Performance
Voltage Error Amplifier, Differential Current Feedback
Amplifiers, Precision Oscillator and Saw−tooth Generator,
and PWM Comparators with Hysteresis. The controller also
supports power saving mode as per Intel VR11.1 by
accurately monitoring the current and switching between
multi−phase and single phase operations as requested by the
microprocessor system. Protection features include:
Undervoltage Lockout, Soft−Start, Overcurrent Protection,
Overvoltage Protection, and Power Good Monitor.
V Diffout + V out ) 1.3 V * V dac * V outreturn
This signal then goes through a standard compensation
circuit and into the inverting input of the error amplifier. The
non−inverting input of the error amplifier is also connected
to the 1.3 V reference. The 1.3 V reference then is subtracted
out and the error signal at the comp pin of the error amplifier
is as normally expected:
V comp + V dac * V out
The non−inverting input of the remote sense amplifier is
pulled low through a small current sink during a fault
condition to prevent accidental charging of the regulator
output.
Precision Programmable DAC
A precision flexible DAC is provided. The DAC will
conform to 2 different specifications: AMD or VR11.1. The
VID7/AMD pin is provided to determine which DAC
specification will be used and which soft−start mode the part
will use for power up. There are two soft−start modes. If
VID7/AMD is above it’s threshold the device will soft−start
and ramp directly to the DAC code present on the VID
inputs. The following truth table describes the functionality:

2/3/4 Phase Operation
The part can be configured to 2−, 3−, or 4−phase mode. In
2− or 3−phase mode, the internal drivers will be used. In
4−phase mode, an external driver must be used to drive
phase 4. The NCP5359 driver is suggested to be used with
the controller. The input to G4 pin will decide which phase
mode the system is in operation. Please refer to the
Application Schematics for more information.
High Performance Voltage Error Amplifier
A high performance voltage error amplifier is provided.
The error amplifier’s inverting input is VFB and its output
is COMP. A standard type 3 compensation circuit is used
compensate the system. This involves a 3 pole, 2 zero
compensation network. The comp pin is pulled to ground
before soft−start for smooth start up.
Differential Current Sense
VID INPUTS
Four differential amplifiers are provided to sense the
output current of each phase. These current sense amplifiers
sense the current through the corresponding phase. A
voltage is generated across a current sense element such as
an inductor or sense resistor. The sense element should be
between 0.5 mW and 1.5 mW. It is possible to sense both
negative and positive going current. The information is used
to create the signal CSSUM and provide feedback for
current sharing.
VID0−VID7 control the target regulation voltage during
normal operation. In AMD mode the VID capture is enabled
just before soft start. In VR11 mode the VID capture is
enabled at the end of the VBOOT waiting period. If the VID
is valid the DAC will track to it. If an invalid VID occurs it
will be ignored for 10 ms before the controller shuts down.
Remote Sense Amplifier
A high performance differential amplifier is provided to
accurately sense the output voltage of the regulator. The
non−inverting input should be connected to the regulator’s
output voltage. The inverting input should be connected to
the return line of the regulator. Both connection points are
intended to be at a remote point so that the most accurate
reading of the output voltage can be obtained. The amplifier
is configured in a very unique way. First, the gain of the
amplifier is internally set to unity. Second, both the inverting
and non−inverting inputs of the amplifier are summing
nodes. The inverting input sums the output voltage return
Precision Oscillator
A programmable precision oscillator is provided. This
oscillator is programmed by the summed resistance of an
oscillator resistor and a current limit resistor. The output
voltage of this pin is used as the reference for the current
limit. The oscillator frequency range is 125 KHz/phase to
1000 KHz/phase. The oscillator frequency is proportional to
the current drawn out of the OSC pin.

NCP5395
PWM Comparators
voltage exceeds the DAC voltage by 185 mV, or 285 mV if
in AMD mode, the VR_RDY flag will transition low the
high side gate drivers set to low, and the low side gate drivers
are all brought to high until the voltage falls below the OVP
threshold. If the over voltage trip 8 times the output voltage
will shut down. The OVP will not shut down the controller
if it occurs during soft−start. This is to allow the controller
to pull the output down to the DAC voltage and start up into
a pre−charged output.
Four PWM comparators are incorporated within the IC.
The non−inverting input of the comparators is connected to
the output of the error amplifier. The inverting input is
connected to a summed output of the phase current and the
oscillator ramp voltage with an offset. The output of the
comparator generates the PWM control signals.
During steady state operation, the duty cycle will center
on the valley of the saw−tooth waveform. During a transient
event, the controller will operate somewhat hysteretic, with
the duty cycle climbing along either the down ramp, up
ramp, or both.
VCCP Power ON Reset OVP
The VCCP power on reset OVP feature is used to protect
the CPU during start up. When VCCP is higher than 3.2 V, the
gate driver will monitor the switching node SW pin. If
SWNx pin higher than 1.9 V, the bottom gate will be forced
to high for discharge of the output capacitor. This works best
if the 5 volt standby is diode OR’ed into VCCP with the 12 V
rail. The fault mode will be latched and the DRVON pin will
be forced to low, unless VCCP is reduced below the UVLO
threshold.
Soft−Start
Soft−start is implemented internally. A digital counter
steps the DAC up from zero to the target voltage based on the
predetermined rate in the spec table. There are 2 possible
soft start modes: VR11 and AMD. AMD mode simply ramps
Vcore from 0 V directly to the DAC setting. The VR11 mode
ramps DAC to 1.1 V, pauses for 500 ms, reads the DAC
setting, then ramps to the final DAC setting.
Power Saving Mode
The controller is designed to allow power saving mode to
maintain a maximum efficiency. When a low PSI signal
from microcontroller is received, the controller will keep
one phase operating while shedding other phases. The active
one phase will operate in diode emulation mode, minimizing
power losses in light load. When the low PSI signal is
de−asserted, the dropped phases will be pulled back in to be
ready for heavy load.
Digital Slew Rate Limiter / Soft Start Block
The slew rate limiter and the soft−start block are to be
implemented with a digital up/down counter controlled by
an oscillator that is synchronized to VID line changes.
During soft start the DAC will ramp at the soft−start rate,
after soft start is complete the ramp rate will follow either the
Intel or the AMD slew rate depending on the mode.
Under Voltage Lockouts
Adaptive Non−overlap
An under voltage circuit senses the VCC input of the
controller and the VCCP input of the driver. During power up
the input voltage to the controller is monitored. The PWM
outputs and the soft start circuit are disabled until the input
voltage exceeds the threshold voltage of the comparators.
Hysteresis is incorporated within the comparators.
The DRVON is held low until VCCP reaches the start
threshold during startup. If VCCP decreases below the stop
threshold, the output gate will be forced low unit input
voltage VCCP rises above the startup threshold.
The non−overlap dead time control is used to avoid shoot
through damage to the power MOSFETs. When the PWM
signal pull high, DRVL will go low after a propagation
delay, the controller monitors the switching node (SWN) pin
voltage and the gate voltage of the MOSFET to know the
status of the MOSFET. When the low side MOSFET status
is off an internal timer will delay turn on of the high–side
MOSFET. When the PWM pull low, gate DRVH will go low
after the propagation delay (tpdDRVH). The time to turn off
the high side MOSFET is depending on the total gate charge
of the high−side MOSFET. A timer will be triggered once
the high side MOSFET is turn off to delay the turn on the
low−side MOSFET.
Over Current Latch
A programmable over current latch is incorporated within
the IC. The oscillator pin provides the reference voltage for
this pin. A resistor divider from the OSC pin generates the
ILIM voltage. The latch is set when the current information
on Vdroop exceeds the programmed voltage plus a 1.3 V
offset. DRVON is immediately set low. To recover the part
must be reset by the EN pin or by cycling VCC.
Layout Guidelines
Layout is very important thing for design a DC−DC
converter. Bootstrap capacitor and Vin capacitor are most
critical items, it should be placed as close as to the controller
IC. Another item is using a GND plane. Ground plane can
provide a good return path for gate drives for reducing the
ground noise. Therefore GND pin should be directly
connected to the ground plane and close to the low−side
MOSFET source pin. Also, the gate drive trace should be
considered. The gate drives has a high di/dt when switching,
therefore a minimized gate drives trace can reduce the di/dv,
raise and fall time for reduce the switching loss.
UVLO Monitor
If the output voltage falls greater than 300 mV below the
DAC voltage for more than 5 ms the UVLO comparator will
trip sending the VR_RDY signal low.
Over Voltage Protection
The output voltage is monitored at the input of the
differential amplifier. During normal operation, if the output
