Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

FAN4800AS/CS/01S/2S
PFC/PWM Controller Combination
Features
Description
Pin-to-Pin Compatible with ML4800 and FAN4800
and CM6800 and CM6800A
PWM Configurable for Current Mode or
Feedforward Voltage-Mode Operation
Internally Synchronized Leading-Edge PFC and
Trailing-Edge PWM in One IC
The highly integrated FAN4800AS/CS/01S/02S parts
are specially designed for power supplies that consist of
boost PFC and PWM. They require very few external
components to achieve versatile protections /
compensation. They are available in 16-pin DIP and
SOP packages.
Low Operating Current
Innovative Switching-Charge Multiplier Divider
Average-Current Mode for Input-Current Shaping
PFC Over-Voltage and Under-Voltage Protections
PFC Feedback Open-Loop Protection
Cycle-by-Cycle Current Limiting for PFC/PWM
Power-on Sequence Control and Soft-Start
Brownout Protection
Interleaved PFC/PWM Switching
Improved Efficiency at Light Load
fRTCT=4•fPFC=4•fPWM for FAN4800AS/01S
fRTCT=4•fPFC=2•fPWM for FAN4800CS/02S
The PWM can be used in either current or voltage
mode. In voltage mode, feed-forward from the PFC
output bus can reduce the secondary output ripple.
Compared with older productions, ML4800 and
FAN4800,
FAN4800AS/CS/01S/02S
have
lower
operation current that saves power consumption in
external devices. FAN4800AS/CS/01S/02S have
accurate 49.9% maximum duty of PWM that makes the
hold-up time longer. Brownout protection and PFC softstart functions available in this series are not available in
ML4800 and FAN4800.
To evaluate FAN4800AS/CS/01S/02S for replacing
existing FAN4800 and ML4800 boards, five things must
be completed before the fine-tuning procedure:
1.
Change RAC resister from the old value to a higher
resister: between 6 MΩ to 8 MΩ.
2.
Change RT/CT pin from the existing values to
RT=6.8kΩ and CT=1000 pF to have fPFC=64 kHz
and fPWM=64 kHz.
3.
The VRMS pin needs to be 1.224 V at VIN=85 VAC
for universal input application from line input from
85 VAC to 270 VAC.
4.
At full load, the average VVEA needs to be ~4.5 V
and the ripple of VVEA needs to be less than
400 mV.
5.
For the Soft-Start pin, the soft-start current has
been reduced to half the FAN4800 capacitor.

FAN4800AS/CS/01S/02S — PFC/PWM Controller Combination
Typical Characteristics
The FAN4800AS/CS/01S/02S consist of an average
current controlled, continuous-boost, Power Factor
Correction (PFC) front-end and a synchronized Pulse
Width Modulator (PWM) back-end. The PWM can be
used in current or voltage mode. In voltage mode,
feedforward from the PFC output bus can help improve
the line regulation of PWM. In either mode, the PWM
stage uses conventional trailing-edge, duty-cycle
modulation. This proprietary leading / trailing edge
modulation results in a higher usable PFC error amplifier
bandwidth and can significantly reduce the size of the
PFC DC bus capacitor.
IGAINMOD =
I AC × (VEA − 0.7 )
×K
(1)
VRMS 2
Note that the output current of the gain modulator is
limited around 159 μA and the maximum output voltage
of the gain modulator is limited to 159 μA x
5.7 k=0.906 V. This 0.906 V also determines the
maximum input power. However, IGAINMOD cannot be
measured directly from ISENSE. ISENSE=IGAINMOD –
IOFFSET and IOFFSET can only be measured when VVEA is
less than 0.5 V and IGAINMOD is 0 A. Typical IOFFSET is
around 31 μA ~ 48 μA.
The synchronization of the PWM with the PFC simplifies
the PWM compensation due to the controlled ripple on
the PFC output capacitor (the PWM input capacitor).
Selecting RAC for the IAC Pin
The IAC pin is the input of the gain modulator and also a
current mirror input that requires current input. Selecting
a proper resistor, RAC, provides a good sine wave
current derived from the line voltage and helps program
the maximum input power and minimum input line
voltage. RAC=VIN peak x 56 kΩ. For example, if the
minimum line voltage is 75 VAC, the RAC=75 x 1.414 x
56 kΩ=6 MΩ.
In addition to power factor correction, a number of
protection features are built into this series. They include
soft-start, PFC over-voltage protection, peak current
limiting, brownout protection, duty cycle limiting, and
under-voltage lockout (UVLO).
Gain Modulator
Current Amplifier Error, IEA
The gain modulator is the heart of the PFC, as the
circuit block controls the response of the current loop to
line voltage waveform and frequency, RMS line voltage,
and PFC output voltages. There are three inputs to the
gain modulator:
The current error amplifier’s output controls the PFC
duty cycle to keep the average current through the boost
inductor a linear function of the line voltage. At the
inverting input to the current error amplifier, the output
current of the gain modulator is summed with a current,
which results in a negative voltage being impressed
upon the ISENSE pin.
1. A current representing the instantaneous input
voltage (amplitude and wave shape) to the PFC. The
rectified AC input sine wave is converted to a
proportional current via a resistor and is fed into the
gain modulator at IAC. Sampling current in this way
minimizes ground noise, required in high-power,
switching-power conversion environments. The gain
modulator responds linearly to this current.
The negative voltage on ISENSE represents the sum of
all currents flowing in the PFC circuit and is typically
derived from a current-sense resistor in series with the
negative terminal of the input bridge rectifier.
2. A voltage proportional to the long-term RMS AC line
voltage, derived from the rectified line voltage after
scaling and filtering. This signal is presented to the
gain modulator at VRMS. The output of the gain
modulator is inversely proportional to VRMS (except at
unusually low values of VRMS, where special gain
contouring takes over to limit power dissipation of the
circuit components under brownout conditions).
The inverting input of the current error amplifier is a
virtual ground. Given this fact, and the arrangement of
the duty cycle modulator polarities internal to the PFC,
an increase in positive current from the gain modulator
causes the output stage to increase its duty cycle until
the voltage on ISENSE is adequately negative to cancel
this increased current. Similarly, if the gain modulator’s
output decreases, the output duty cycle decreases to
achieve a less negative voltage on the ISENSE pin.
3. The output of the voltage error amplifier, VEA. The
gain modulator responds linearly to variations in VVEA.
PFC Cycle-By-Cycle Current Limiter
In addition to being a part of the current feedback loop,
the ISENSE pin is a direct input to the cycle-by-cycle
current limiter for the PFC section. If the input voltage at
this pin is less than -1.15 V, the output of the PFC is
disabled until the protection flip-flop is reset by the clock
pulse at the start of the next PFC power cycle.
The output of the gain modulator is a current signal, in
the form of a full wave rectified sinusoid at twice the line
frequency. This current is applied to the virtual ground
(negative) input of the current error amplifier. In this way,
the gain modulator forms the reference for the current
error loop and ultimately controls the instantaneous
current draw of the PFC from the power line. The
general form of the output of the gain modulator is:

Functional Description
Error Amplifier Compensation
To improve power supply reliability, reduce system
component count, and simplify compliance to UL1950
safety standards; the FAN4800AS/CS/01S/02S includes
TriFault Detect™ technology. This feature monitors
FBPFC for certain PFC fault conditions.
The PWM loading of the PFC can be modeled as a
negative resistor because an increase in the input voltage
to the PWM causes a decrease in the input current. This
response dictates the proper compensation of the two
transconductance error amplifiers. Figure 26 shows the
types of compensation networks most commonly used for

FAN4800AS/CS/01S/02S — PFC/PWM Controller Combination
TriFault Detect™
Pulse Width Modulator (PWM)
To improve the efficiency, the system can reduce PFC
switching loss at low line and light load by reducing the
PFC output voltage. The two-level PFC output of the
FAN4801S/02S can be programmable.
The operation of the PWM section is straightforward,
but there are several points that should be noted.
Foremost among these is the inherent synchronization
of PWM with the PFC section of the device, from which
it also derives its basic timing. The PWM is capable of
current-mode or voltage-mode operation. In currentmode applications, the PWM ramp (RAMP) is usually
derived directly from a current-sensing resistor or
current transformer in the primary side of the output
stage. It is thereby representative of the current flowing
in the converter’s output stage. ILIMIT, which provides
cycle-by-cycle current limiting, is typically connected to
RAMP in such applications. For voltage-mode operation
and certain specialized applications, RAMP can be
connected to a separate RC timing network to generate
a voltage ramp against which FBPWM is compared.
Under these conditions, the use of voltage feedforward
from the PFC bus can assist in line regulation accuracy
and response. As in current-mode operation, the ILIMIT
input is used for output stage over-current protection.
No voltage error amplifier is included in the PWM stage,
as this function is generally performed on the output
side of the PWM’s isolation boundary. To facilitate the
design of opto-coupler feedback circuitry, an offset has
been built into the PWM’s RAMP input that allows
FBPWM to command a 0% duty cycle for input voltages
below typical 1.5 V.
As Figure 27 shows, FAN4801S/02S detect the voltage
of VEA and VRMS pins to determine if the system
operates low line and light load. At the second-level
PFC, there is a current of 20 µA through RF2 from the
FBPFC pin. The second-level PFC output voltage can
be calculated as.
Output ≅
RF 1 + RF 2
× ( 2.5V − 20 μ A × RF 2 )
RF 2
(3)
For example, if the second-level PFC output voltage is
expected as 300 V and normal voltage is 387 V,
according to the equation, RF2 is 28 kΩ RF1 is 4.3 MΩ.
The programmable range of second level PFC output
voltage is 340 V ~ 300 V.
PWM Cycle-by-Cycle Current Limiter
Figure 27.
The ILIMIT pin is a direct input to the cycle-by-cycle
current limiter for the PWM section. Should the input
voltage at this pin exceed 1 V, the output flip-flop is reset
by the clock pulse at the start of the next PWM power
cycle. When the ILIMIT triggers the cycle-by-cycle bi-cycle
current, it limits the PWM duty cycle mode and the power
dissipation is reduced during the dead-short condition.
Two-Level PFC Scheme
Oscillator (RT/CT)
The oscillator frequency is determined by the values of
RT and CT, which determine the ramp and off-time of
the oscillator output clock:
VIN OK Comparator
1
fRT / CT =
(4)
tRT / CT + tDEAD
The dead time of the oscillator is derived from the
following equation:
The VIN OK comparator monitors the DC output of the
PFC and inhibits the PWM if the voltage on FBPFC is
less than its nominal 2.4 V. Once the voltage reaches
2.4 V, which corresponds to the PFC output capacitor
being charged to its rated boost voltage, soft-start begins.
VREF − 1
tRT / CT = CT × RT × ln
VREF − 3.8
at VREF=7.5 V and tRT/CT=CT x RT x 0.56.
PWM Soft-Start (SS)
(5)
PWM startup is controlled by selection of the external
capacitor at soft-start. A current source of 10 µA
supplies the charging current for the capacitor and
startup of the PWM begins at 1.5 V.
The dead time of the oscillator is determined using:
2.8V

The dead time is so small (tRT/CT>>tDEAD) that the
operating frequency can typically be approximated by:

FAN4800AS/CS/01S/02S — PFC/PWM Controller Combination
Two-Level PFC Function
Leading/Trailing Edge Modulation
When the PWM section is used in current mode, RAMP
is generally used as the sampling point for a voltage,
representing the current in the primary of the PWM’s
output transformer. The voltage is derived either from a
current-sensing resistor or a current transformer. In
voltage mode, RAMP is the input for a ramp voltage
generated by a second set of timing components (RRAMP,
CRAMP) that have a minimum value of 0V and a peak
value of approximately 6 V. In voltage mode,
feedforward from the PFC output bus is an excellent
way to derive the timing ramp for the PWM stage.
Conventional PWM techniques employ trailing-edge
modulation, in which the switch turns on right after the
trailing edge of the system clock. The error amplifier
output is then compared with the modulating ramp up.
The effective duty cycle of the trailing-edge modulation
is determined during the on-time of the switch.
In the case of leading-edge modulation, the switch is
turned off exactly at the leading edge of the system
clock. When the modulating ramp reaches the level of
the error amplifier output voltage, the switch is turned
on. The effective duty-cycle of the leading-edge
modulation is determined during off-time of the switch.
Generating VDD
After turning on the FAN4800AS/CS/01S/02S at 11 V,
the operating voltage can vary from 9.3 V to 28 V. The
threshold voltage of the VDD OVP comparator is 28 V
and its hysteresis is 1 V. When VDD reaches 28 V,
OPFC is LOW and the PWM section is not disturbed.
There are two ways to generate VDD: use auxiliary
power supply around 15 V or use bootstrap winding to
self-bias the FAN4800AS/CS/01S/02S system. The
bootstrap winding can be taped from the PFC boost
choke or the transformer of the DC-to-DC stage.
