Description
This evaluation board user’s manual provides elementary
information about a high efficiency, low no-load power consumption
reference design that is targeting power laptop adapter or similar type
of equipment that accepts 19.5 VDC on the input.
The power supply implements PFC front stage to assure unity power
factor and low THD, current mode LLC power stage to enhance
transient response and secondary side synchronous rectification to
maximize efficiency. This design focuses mainly on the NCP1399
current mode LLC controller description – please refer to NCP1602
and NCP4305 material to gain more information about these devices.
The NCP1399 is a current mode LLC controller which means that
the operating frequency of an LLC converter is not controlled via
voltage (or current) controlled oscillator but is directly derived from
the resonant capacitor voltage signal and actual feedback level. This
control technique brings several benefits compare to traditional
voltage mode controllers like improved line and load transient
response and inherent out of zero voltage switching protection. The
LLC controller also features built-in high voltage startup and PFC
operation control pins that ease implementation of a power supply
with PFC front stage and no standby power supply on board.
The enhanced light lad operation of the LLC controller allows
SMPS design to pass the latest no-load and light load consumption
limits and still keeping output regulated with excellent transient
response from no-load to full-load steps.

in the same time to assure fast LLC_CS pin signal
stabilization after application startup – this is achieved by
resistor R148. The series resistor R23, R24, and R64 is used to
limit maximum current that can flow into the LLC_CS pin.
The FB optoucoupler OK1 is connected to the LLC_FB pin
and defines converter output by pulling down this pin when
lower output power is needed. Capacitor C50 forms high
frequency pole in FB loop characteristics and helps to
eliminate eventual noise that could be coupled to the FB pin
by parasitic coupling paths. The Brow-Out resistor sensing
network was already described in PFC section as it is shared
with PFC feedback sensing. The Skip/REM pin of the
NCP1399 is used for skip threshold adjustment in this
demo-board option. Resistors R103 and R104 are used for this
purpose together with noise filtering capacitor C57. The
over-voltage and over-temperature protections are
implemented via OVP/OTP pin by using resistor R67,
temperature dependent resistor NTC1, filtering capacitor
C44 and optocoupler OK2. The OVP comparator is located
on the secondary side to assure maximum OVP circuitry
accuracy. The PFC ON/OFF function is not used in this
revision of demo-board – i.e. the bulk voltage is regulated to
nominal level during entire board operation (full, medium,
light or no-load conditions) thus the P_ON/OFF pin is
connected to ground via resistor R105. The PFC_MODE pin
provides bias to the PFC controller via series resistor R100
after high enough voltage is available on the LLC VCC
capacitors C37. The VCC decoupling capacitor C54 and also
bootstrap capacitor for high side driver powering C53 are
located as close to the LLC controller package as possible to
minimize parasitic inductive coupling to other IC adjust
components due to high driver current peaks that are present
in the circuit during drivers rising and falling edges
transitions. The bootstrap capacitor is charged via HV
bootstrap diode D23 and series resistor R96 which limits
The input EMI filter is formed by components L8, L2,
L5, C47, C1, C4, C6, R5, R6, R10 and R48. The IC1 (NCP4810)
with safety resistors R1, R16, R43, R53 is used to assure
lose-less X2 capacitor discharge function after application
is disconnected from the mains.
The PFC power stage uses standard boost PFC topology
formed by power components B1, L1, D5, Q1, R11, R38, and
bulk capacitor C16. The PFC controller IC8 (NCP1602)
senses input voltage indirectly – via PFC power MOSFET
drain voltage sensing network R135, R134, R102 and R101.
The PFC coil current is sensed by the shunt resistors R11 and
R38. The series resistor R81 defines maximum PFC front
stage peak current. The PFC feedback divider is shared with
LLC brown-out sensing network in order to reduce
application no-load power consumption. The PFC FB/LLC
BO divider is formed by resistors R17, R28, R34, R46, R129,
R130, R132, R133 and R149. The FB signal is filtered by
capacitor C26 to overcome possible troubles caused by the
parasitic capacitive coupling between pin and other nodes
that handle high dV/dt signals. The internal bulk voltage
regulator compensation C40, C36 and R75 is connected to the
IC8 pin 1. The PFC MOSFET is driven via circuitry R19,
R25, R26, R33, D7 and Q4. This solution allows to select
needed turn-on and turn-off process speed for Q1 and also to
handle gate discharge current in local loop – minimizing
EMI caused by the driver loop.
The LLC power stage primary side composes from
these devices: MOSFETs Q2, Q3, external resonant coil L3,
transformer TR1 and resonant capacitor C18. The IC3
(NCP1399Ax) LLC controller senses primary current
indirectly – via resonant capacitor voltage monitoring which
is divided down by capacitive divider R32, C17, C29, C32 and
C62. The capacitive divider has to provide minimum phase
shift between resonant capacitor signal and divided signal
on the LLC_CS pin. The capacitive divide has to be loaded

mode – this helps to reduce no-load power consumption of
application. The trigger/disable function of NCP4305 is not
used in this application thus the corresponding pins are
grounded.
The output voltage of the converter is regulated by
Secondary Side Sleep mode Controller NCP4354A − IC101.
The regulation optocoupler OK1 is driven via resistor R18
which defines loop gain. The NCP4354 is biased via resistor
R123 with decoupling capacitor C109. The output voltage is
adjusted by divider R65, R117, R118, R127 and R119. The
feedback loop compensation network is formed partially by
these components, resistor R128 and capacitor C111. The
output filtering capacitor bank composes from low ESR
capacitors C8 to C11. Output filter L1, C5 is used to clean out
output voltage from switching glitches.
The secondary side OVP sense circuitry is using zener
diode D4, resistors R82, R84 and capacitor C30. The OVP
threshold is adjusted by selected type of zener diode.
There are several options prepared in the PCB layout so
that customer can modify demo-board according to his
target application needs. Mentioned options for instance
allow implementation of off-mode control from secondary
side to further reduce no-load power consumption or
different PFC front stage controller implementation.
charging current and Vboot to HB power supply slope during
initial C53 charging process. The gate driver currents are
reducer by added series resistors R54, R55 to optimize EMI
signature of the application.
The primary controllers bias voltage limiter circuitry
is used in order to restrict upper value of the primary VCC
voltage to approximately 13 V. The VCC limiter composes
of these components: resistors R4, R150, capacitors C2, C3,
diodes D3, D2, D6, D26 and transistor Q6.
The secondary side synchronous rectification is located
on separated Daughter-card and uses IC1 and IC2 SR
controllers – NCP4305D. The SR MOSFTEs for each SR
channel are Q1 and Q2. RC snubber circuits C9, R1, C10 and
R11, are used to damp down the parasitic ringing and thus
limit the maximum peak voltage on the SR MOSFETs. The
SR controllers are supplied from converter output via
resistors R1 and R4. These resistors form RC filter with
decoupling capacitors C1 to C6. The minimum on-time – R3,
R6 and minimum off-time – R2, R5 resistors define needed
blanking periods that help to overcome SR controllers false
triggering to ringing in the SR power stage. The light load
detection circuit (LLD) is formed by resistors R7, R8, R9
capacitor C7, C8, and diodes D1, D2. The SR controllers are
disabled by LLD circuitry when application enters skip
