Highly Integrated Green-Mode PWM Controller
Features
Description
This highly integrated PWM controller provides several
features to enhance the performance of flyback
converters.
Internal High-Voltage Startup
Low Operating Current (Maximum: 2mA)
Adaptive Decreasing of PWM Frequency to 23KHz
at Light-Load condition to Improve Light-Load
Efficiency
To minimize standby power consumption, a proprietary
adaptive green-mode function reduces switching
frequency at light-load condition. To avoid acoustic-
noise problems, the minimum PWM frequency is set
above 23kHz. This green-mode function enables the
power supply to meet international power conservation
requirements, such as Energy Star®. With the internal
high-voltage startup circuitry, the power loss caused by
bleeding resistors is also eliminated. To further reduce
power consumption, FAN6755 uses the BiCMOS
process, which allows an operating current of only 2mA.
The standby power consumption can be under 100mW
for most of LCD monitor power supply designs.
Frequency Hopping to Reduce EMI Emission
Fixed PWM Frequency: 65KHz
Internal Leading-Edge Blanking
Built-in Synchronized Slope Compensation
Auto-Restart Protection : Feedback Open-Loop
Protection (OLP), VDD Over-Voltage Protection
(OVP), Over-Temperature Protection (OTP), and
Line Over-Voltage Protection
FAN6755 integrates a frequency-hopping function that
reduces EMI emission of a power supply with minimum
line filters. Its built-in synchronized slope compensation

compensation ensures constant output power limit over

FAN6755 provides many protection functions. The
internal feedback open-loop protection circuit protects
the power supply from open feedback loop condition or
output short condition. It also has line under-voltage
protection (brownout protection) and over-voltage
protection using an input voltage sensing pin (VIN).

Functional Description
Startup Current
Gate Output / Soft Driving
For startup, the HV pin is connected to the line input
(1N4007 / 100KΩ recommended) or bulk capacitor
through a resistor, RHV. Startup current drawn from pin
HV (typically 3.5mA) charges the hold-up capacitor
through the diode and resistor. When the VDD capacitor
level reaches VDD-ON, the startup current switches off. At
this moment, the VDD capacitor only supplies the
FAN6755 to maintain VDD before the auxiliary winding of
the main transformer to provide the operating current.
The BiCMOS output stage is a fast totem-pole gate
driver. Cross conduction has been avoided to minimize
heat dissipation, increase efficiency, and enhance
reliability. The output driver is clamped by an internal
18V Zener diode to protect power MOSFET transistors
against undesirable gate over voltage. A soft driving
waveform is implemented to minimize EMI.
Soft Start
For many applications, it is necessary to minimize the
inrush current at startup. The built-in 5.5ms soft-start
circuit significantly reduces the startup current spike
and output voltage overshoot.
Operating Current
Operating current is around 2mA. The low operating
current enables better efficiency and reduces the
requirement of VDD hold-up capacitance.
Slope Compensation
Green-Mode Operation
The sensed voltage across the current-sense resistor is
used for peak-current-mode control and pulse-by-pulse
current limiting. Built-in slope compensation improves
stability and prevents sub-harmonic oscillation.
FAN6755 inserts a synchronized positive-going ramp at
every switching cycle.
The proprietary green-mode function provides an off-
time modulation to reduce the switching frequency in
light-load and no-load conditions. The on time is limited
for better abnormal or brownout protection. VFB, which is
derived from the voltage feedback loop, is taken as the
reference. Once VFB is lower than the threshold voltage,
switching frequency is continuously decreased to the
minimum green-mode frequency of around 23KHz.
Constant Output Power Limit
For constant output power limit over universal input-
voltage range, the peak-current threshold is adjusted by
the voltage of the VIN pin. Since the VIN pin is
connected to the rectified AC input line voltage through
the resistive divider, a higher line voltage generates a
higher VIN voltage. The threshold voltage decreases as
VIN increases, making the maximum output power at
high-line input voltage equal to that at low-line input.
The value of R-C network should not be so large that it
affects the power limit (shown in Figure 21). Usually, R
Current Sensing / PWM Current Limiting
Peak-current-mode control is utilized to regulate output
voltage and provide pulse-by-pulse current limiting. The
switch current is detected by a sense resistor into the
SENSE pin. The PWM duty cycle is determined by this
current sense signal and VFB, the feedback voltage.
When the voltage on the SENSE pin reaches around
VCOMP=(VFB–0.6)/4,
a
switch cycle is terminated
immediately. VCOMP is internally clamped to a variable
voltage around 0.83V for output power limit.
and
respectively.
C should be less than 100Ω and 470pF,
Leading-Edge Blanking (LEB)
Each time the power MOSFET is switched on, a turn-on
spike occurs on the sense resistor. To avoid premature
termination of the switching pulse, a leading-edge
blanking time is built in. During this blanking period, the
current-limit comparator is disabled and cannot switch
off the gate driver.
Under-Voltage Lockout (UVLO)
The turn-on and turn-off thresholds are fixed internally
at 16V and 7.8V in normal mode. During startup, the
hold-up capacitor must be charged to 16V through the
startup resistor to enable the IC. The hold-up capacitor
continues to supply VDD before the energy can be
delivered from auxiliary winding of the main transformer.
VDD must not drop below 7.8V during startup. This
UVLO hysteresis window ensures that the hold-up
capacitor is adequate to supply VDD during startup.

VDD Over-Voltage Protection
Limited Power Control
VDD over-voltage protection prevents damage due to
abnormal conditions. Once the VDD voltage is over the
over-voltage protection voltage (VDD-OVP), and lasts for
The FB voltage is saturated HIGH when the power
supply output voltage drops below its nominal value and
shut regulator (KA431) does not draw current through
the opto-coupler. This occurs when the output feedback
loop is open or output is short circuited. If the FB
voltage is higher than a built-in threshold for longer than
t
D-VDDOVP, the PWM pulses are disabled. When the VDD
voltage drops below the UVLO, PWM pulses start
again. Over-voltage conditions are usually caused by
open feedback loops.
t
D-OLP, PWM output is turned off. As PWM output is
turned off, VDD begins decreasing since no more energy
is delivered from the auxiliary winding.
Brownout Protection
When VDD goes below the turn-off threshold (~7.8V),
the controller is totally shut down. VDD is charged up to
the turn-on threshold voltage of 16V through the startup
resistor until PWM output is restarted. This protection
feature continues as long as the over loading condition
persists. This prevents the power supply from
overheating due to overloading conditions.
Since the VIN pin is connected through a resistive
divider to the rectified AC input line voltage, it can also
be used for brownout protection. If VIN is less than 0.7V,
the PWM output is shut off. When VIN reaches over
0.9V, the PWM output is turned on again. The
hysteresis window for ON/OFF is around 0.2V. The
brownout voltage setting is determined by the potential
divider formed with RUpper and RLower. Equations to
calculate the resistors are shown below:
Noise Immunity
Noise on the current sense or control signal may cause
significant pulse-width jitter, particularly in continuous-
conduction mode. Slope compensation helps alleviate
this problem. Good placement and layout practices
should be followed. Avoiding long PCB traces and
component leads, locating compensation and filter
components near the FAN6755, and increasing the
power MOS gate resistance improve performance.

×VAC 2, (unit = V)

Thermal Overload Protection
Thermal overload protection limits total power
dissipation. When the junction temperature exceeds TJ=
+135°C, the thermal sensor signals the shutdown logic
and turns off most of the internal circuitry. The thermal
sensor turns internal circuitry on again after the IC’s
junction temperature drops by 25°C. Thermal overload
protection is designed to protect the FAN6755 in the
event of a fault condition. For continual operation, do
not exceed the absolute maximum junction temperature
of TJ = +150°C.
