3−In−1 PWM Dual Buck and
Linear DDR Power
Controller
The NCP5210, 3−In−1 PWM Dual Buck and Linear DDR Power
Controller, is a complete power solution for MCH and DDR memory.
This IC combines the efficiency of PWM controllers for the VDDQ
supply and the MCH core supply voltage with the simplicity of linear
regulator for the VTT termination voltage.
This IC contains two synchronous PWM buck controller for driving
four external NFETs to form the DDR memory supply voltage
(VDDQ) and the MCH regulator. The DDR memory termination
regulator (VTT) is designed to track at the half of the reference voltage
with sourcing and sinking current.
Protective features include, soft−start circuitry, under−voltage
monitoring of 5VDUAL, and BOOT voltage, and thermal shutdown.
The IC is packaged in a QFN−20.

DETAILED OPERATION DESCRIPTIONS
General
The ACPI control logic is enabled by the assertion of
_VREFGD. Once the ACPI control is activated, the power
up sequence starts by waking up the 5VDUAL voltage
monitor block. If the 5VDUAL supply is within the preset
levels, the BOOT under voltage monitor block is then
enabled. After the BOOT UVLO is asserted HIGH, the
ACPI control triggers this device from S5 shutdown mode
into S0 normal operating mode by activating the soft−start
of DDQ switching regulator, providing BUF_CUT
remaining LOW.
Once the DDQ regulator is in regulation and the soft−start
interval is completed, the _InRegDDQ signal is asserted
HIGH to enable the VTT regulator as well as the V1P5
switching regulator.
The NCP5210 3−In−1 PWM Dual Buck Linear DDR
Power Controller contains two high efficiency PWM
controllers and an integrated two−quadrant linear regulator.
The VDDQ supply is produced by a PWM switching
controller with two external NFETs. The VTT termination
voltage is an integrated linear regulator with sourcing and
sinking current capability which tracks at 1/2 VDDQ. The
MCH core voltage is created by the secondary switching
controller.
The inclusion of soft−start, supply under−voltage
monitors, short circuit protection and thermal shutdown,
makes this device a total power solution for the MCH and
DDR memory system. This device is packaged in a
QFN−20.
DDQ Switching Regulator
ACPI Control Logic
In S0 mode the DDQ regulator is a switching synchronous
rectification buck controller driving two external power
NFETs to supply up to 20 A. It employs voltage mode fixed
frequency PWM control with external compensation
switching at 250kHz ± 10%. As shown in Figure 2, the
VDDQ output voltage is divided down and fed back to the
inverting input of an internal amplifier through the FBDDQ
pin to close the loop at VDDQ = VFBQ × (1 + R2/R1). This
amplifier compares the feedback voltage with an internal
reference voltage of 1.200 V to generate an error signal for
the PWM comparator. This error signal is compared with a
fixed frequency RAMP waveform derived from the internal
oscillator to generate a pulse−width−modulated signal. The
PWM signal drives the external NFETs via the TG_DDQ
and BG_DDQ pins. External inductor L and capacitor
COUT1 filter the output waveform. When the IC leaves the
S5 state, the VDDQ output voltage ramps up at a soft−start
rate controlled by the capacitor at the SS pin. When the
regulation of VDDQ is detected in S0 mode, _INREGDDQ
goes HIGH to notify the control block.
In S3 standby mode, the switching frequency is doubled
to reduce the conduction loss in the external NFETs.
The ACPI control logic is powered by the 5VDUAL
supply. It accepts external control at the BUF_CUT input,
and internal supply voltage monitoring signals from two
UVLOs to decode the operating mode in accordance with
state transition diagram in Figure 3.
These UVLOs monitor the external supplies, 5VDUAL
and 12VATX, through 5VDUAL and BOOT pins
respectively. Two control signals, _5VDUALGD and
_BOOTGD, are asserted when the supply voltages are good.
The device powers up initially in the S5 shutdown mode
to minimize the power consumption. When all three supply
voltages are good and BUF_CUT is LOW, the device enters
the S0 normal operating mode. When BUF_CUT transitions
from LOW to HIGH in S0 mode the device goes into the S3
sleep mode. In S3 mode the 12VATX supply collapses. On
transition of BUF_CUT from HIGH to LOW, the device
returns to S0 mode. The IC re−enters S5 mode if one of the
supplies is removed during S0 mode. Transitions from S3 to
S5 or vice versa are not allowed. A timing diagram is shown
in Figure 3.
Table 1 summarizes the operating states of all the
regulators, as well as the conditions of output pins.
S5 To S0 Mode Power Up Sequence
An internal bandgap reference is generated whenever
5VDUAL exceeds 2.7 V. Once this bandgap reference is in
regulation, an internal signal _VREFGD is asserted.

at the half of DDQ_REF. This regulator is stable with any
value of output capacitor greater than 470 F, and is
insensitive to ESR ranging from 1−m to 400 m.
For enhanced efficiency, an active synchronous switch is
used to eliminate the conduction loss contributed by the
forward voltage of a diode or Schottky diode rectifier.
Adaptive non−overlap timing control of the complementary
gate drive output signals is provided to reduce
shoot−through current that degrades efficiency.
Fault Protection of VTT Active Terminator
To provide protection for the internal FETs, bi−directional
current limit preset at 2.4 A magnitude is implemented. This
current limit is also used as constant current source during
VTT startup.
Tolerance of VDDQ
Both the tolerance of VFBQ and the ratio of the external
resistor divider R2/R1 impact the precision of VDDQ. With
the control loop in regulation, VDDQ = VFBQ × (1 +
R2/R1). With a worst case (for all valid operating
conditions) VFBQ tolerance of ±1.5%, a worst case range of
±2% for VDDQ will be assured if the ratio R2/R1 is
specified as 0.9455 ±1%.
MCH Switching Regulator
The secondary switching regulator is identical to the DDQ
regulator except the output is 10 A, no fault protection is
implemented and the soft−start timing is twice as fast with
respect to CSS.
BOOT Pin Supply Voltage
Fault Protection of VDDQ Regulator
In typical application, a flying capacitor is connected
between SWDDQ and BOOT pins. In S0 mode, 12VATX is
tied to BOOT pin through a Schottky diode as well. A 13−V
Zener clamp circuit must clamp this boot strapping voltage
produced by the flying capacitor in S0 mode.
In S3 mode the 12VATX is collapsed and the BOOT
voltage is created by the Schottky diode between 5VDUAL
and BOOT pins as well as the flying capacitor.
In S0 mode, an internal voltage (VOCP) = 5VDUAL – 0.8
sets the current limit for the high−side switch. The voltage
VOCP pin is compared to the voltage at SWDDQ pin when
the high−side gate drive is turned on after a fixed period of
blanking time to avoid false current limit triggering. When
the voltage at SWDDQ is lower than VOCP, an over−current
condition occurs and all regulators are latched off to protect
against over−current. The IC can be powered up again if one
of the supply voltages, 5VDUAL or 12VATX, is recycled.
In S3 mode, this over−current protection feature is
disabled.
Thermal Consideration
Assuming an ambient temperature of 50°C, the maximum
allowed dissipated power of QFN−20 is 2.8 W, which is
enough to handle the internal power dissipation in S0 mode.
To take full advantage of the thermal capability of this
package, the exposed pad underneath must be soldered
directly onto a PCB metal substrate to allow good thermal
contact.
Feedback Compensation of VDDQ Regulator
The compensation network is shown in Figure 2.
VTT Active Terminator
The VTT active terminator is a 2 quadrant linear regulator
with two internal NFETs to provide current sink and source
capability up to 2.0 A. It is activated only when the DDQ
regulator is in regulation in S0 mode. It draws power from
VDDQ with the internal gate drive power derived from
5VDUAL. While VTT output is connecting to the FBVTT
pin directly, VTT voltage is designed to automatically track
Thermal Shutdown
When the junction temperature of the IC exceeds 150°C,
the entire IC is shutdown. When the junction temperature
drops below 115°C, the chip resumes normal operation.
