The NCP81147 is a simple single phase solution with differential
phase current sensing, power saving operation, and gate drivers to
provide accurately regulated power.
MARKING
DIAGRAMS
The adaptive non overlap gate drive and power saving operation
circuit provide a low switching loss and high efficiency solution for
server, notebook, and desktop systems. A high performance
operational error amplifier is provided to simplify compensation of the
system. The NCP81147 features also include soft−start sequence,
accurate overvoltage and over current protection, UVLO for VCC and
VCCP, and thermal shutdown.

being disabled.
Overvoltage Protection (OV)
Soft−Start
If the voltage on the VSEN pin exceeds the overvoltage
threshold (1000 mV or 125% Vref), the NCP81147 will latch
an overvoltage fault. During an overvoltage fault event the
UG pin will be pulled low, and the LG pin will stay high until
the voltage on the VSEN pin goes below 400 mV or 50%
Soft−Start will begin if VCC, VCCP are both above their
UVLO thresholds and EN pin is set free. IC initially waits
a fixed delay time and then ramps the reference in 5.12 ms
(1024 clock cycles when R
open) in closed−loop
osc
regulation. After soft−start, PGOOD signal will be released
with 3 clock cycles delay.
V , then a soft-bleeding resistor will be connected from
ref
switch node to ground to continuously discharge the output
voltage softly. To clear the overvoltage fault, toggling VCC
or EN is needed.
Protection active during soft−start:
• Overvoltage Protection always enabled;
• Undervoltage Protection is enabled after reference
voltage ramps up to 80% of the final value. During
soft−start, a UVP fault will initiate a complete soft
restart.
Undervoltage Protection (UV)
If the voltage on the FB pin falls below the undervoltage
threshold after the softstart cycle completes, the NCP81147
will latch an undervoltage fault. During an undervoltage
fault, both the UG and LG pins will be pulled low. Toggling
VCC power or EN will reset the undervoltage protection.
Synchronization Function
Synchronize through the SYNC pin. Synchronization
function allows different converters to share the same input
filter reducing the resulting RMS current and reducing the
need for total caps to sustain the load. Synchronized systems
also exhibit higher EMI noise immunity and better
regulation.
The device synchronizes to the Falling edge of the SYNC
pin external input signal (eg. high side gate signal, switch
node signal, distribution clock signal), and locks the phase
PreOVP Protection
If the NCP81147 is powered on but not enabled, the VSEN
pin will be monitored for preOVP condition. If the VSEN
exceeds the preset threshold, the device will force LG pin
high to protect the load. The PreOVP function will be
disabled when the device is enabled and the normal OV
function will operate instead.

Vin Detection
During the soft start after the VSEN pin exceeds 80% V ,
UV protection will be enabled; If a UV fault is triggered in
the softstart, it will restart SS after a fixed delay. The UV
protection is to avoid IC to startup without Vin or with
insufficient Vin voltage.
OCP2 will be tripped, the UG and LG will be pulled low and
latched immediately. Toggling VCC power or EN will reset
the Overcurrent protection.
The current sensing R/C network should be selected to
match the inductor time constant as below,

DCR
(Notes: the actual RC network time constant may be
slightly higher)
Overcurrent Protection
NCP81147 measures the differential current sensing
signal through CSP and CSN/VO pin. There are two current
protection levels: OCP1 and OCP2. If the differential
voltage across pin CSP and CSN/VO is over 20 mV (but
below 30 mV) for four consecutive cycles, OCP1 will be
tripped. Both UG and LG will be forced to low to turn off the
high side and low side FETs, it is a latched condition; If the
differential voltage across pin CSP and CSN is over 30 mV,
Thus, OCP1 and OCP2 levels can be configured as,

Light Load Operation
this way, the ripple variation during transition between the
discontinuous and continuous current mode can be
minimized.
In the light load condition, NCP81147 will work in a diode
emulation mode with bottom gate turning off if the inductor
current is below zero. The system therefore works in
discontinuous conduction mode (DCM). The zero current
detection is done by sensing switch node and automatically
adjusted to minimize the low side FET body diode
conduction time (right after LG turns off) in diode emulation
mode.
If the load reduces further, COMP signal will be close or
below the internal ramp bottom triggering minimum on time
operation, the system will start skipping pulses, working in
a reduced frequency range. NCP81147 has an internal
ultrasonic timer to keep the device from working in an audio
frequency and below. This timer initiates after high side gate
off signal and expires after ~30 ms.
Voltage Feedback
The NCP81147 allow the output voltage to be adjusted
from 0.8 V to 5 V via an external resistor divider network
(R1, R2). The controller will regulate the output voltage to
maintain the FB pin voltage to 0.8 V reference voltage. The
relation between the resistor divider network and the output
voltage is as below;
0.8 V
Vout * 0.8 V
R2 + R1 @ ǒ
Ǔ
VOUT
Normally high side gate signal will reset this ultrasonic
timer repeatedly before it expires. In a very light load or load
release, if there is no high side gate pulses until the timer
expires, the low side MOSFET(s) will be forced to turn on
to discharge the output. Through properly compensated
network the comp signal will climb up to generate next burst
of switching pulses and the converter will regulate the
output voltage to its target level. This can last a few cycles
or continuously depending on the system load level.
In light load operation, if synchronization is enabled,
NCP81147 will also check the SYNC pin input signal cycle
by cycle. If the external sync signal is within the
synchronization frequency range, the NCP81147 will
interleave its switching pulses with it after a proper delay. In
