VDD Over-Voltage Protection (OVP)
A highly integrated PWM controller, FAN6862 provides
several features to enhance the performance of flyback
converters. To minimize standby power consumption, a
proprietary green-mode function provides off-time
modulation to continuously decrease the switching
frequency under light-load conditions. Under zero-load
conditions, the power supply enters burst-mode, which
completely shuts off PWM output. Output restarts just
before the supply voltage drops below the UVLO lower
limit. This green-mode function enables power supplies
to meet international power conservation requirements.

Open-Frame SMPS
SMPS with Surge-Current Output, such as for
Printers, Scanners, and Motor Drivers
The FAN6862 is designed for SMPS and integrates a
frequency-hopping function that helps reduce EMI
emission of a power supply with minimum line filters.
The built-in synchronized slope compensation is
proprietary sawtooth compensation for constant output
power limit over universal AC input range. The gate
output is clamped at 18V to protect the external
MOSFET from over-voltage damage.
Other protection functions include VDD over-voltage
protection and over-temperature protection. For overtemperature protection, an external NTC thermistor can
be applied to sense the ambient temperature. When
VDD OVP or OTP is activated, an internal latch circuit
latches off the controller.

Description
Ground.
The FB pin provides the output voltage regulation signal. It provides feedback
to the internal PWM comparator, so that the PWM comparator can control the
duty cycle. This pin also provide for OLP: if VFB is larger than the trigger level
and delays for a long time, the controller stops and restarts.
An external NTC thermistor is connected from this pin to GND for overtemperature protection. The impedance of the NTC decreases at high
temperatures. Once the voltage of the RT pin drops below a threshold,
PWM output is disabled.
This pin senses the voltage across a resistor. When the voltage reaches the
internal threshold, PWM output is disabled. This activates over-current
protection. This pin also provides current amplitude information for currentmode control.
Power Supply Power supply.
Driver Output The totem-pole output driver for driving the power MOSFET.

Startup Operation
Figure 21 shows a typical startup circuit and
transformer auxiliary winding for a FAN6862 application.
Before FAN6862 begins switching operation, it
consumes only startup current (typically 8μA) and the
current supplied through the startup resistor charges
the VDD capacitor (CDD). When VDD reaches turn-on
voltage of 16V (VDD-ON), FAN6862 begins switching and
the current consumed increases to 3mA. Then, the
power required is supplied from the transformer
auxiliary winding. The large hysteresis of VDD (8.5V)
provides more holdup time, which allows using a small
capacitor for VDD. The startup resistor is typically
connected to AC line for a fast reset of latch protection.

Operation Description

Figure 23. Burst Mode Operation
Frequency Hopping
Green-Mode Operation
EMI reduction is accomplished by frequency hopping,
which spreads the energy over a wider frequency range
than the bandwidth measured by the EMI test
equipment. An internal frequency hopping circuit
changes the switching frequency between 60.8kHz and
69.2kHz with a period of 4.4ms, as shown in Figure 24.
The FAN6862 uses feedback voltage (VFB) as an
indicator of the output load and modulates the PWM
frequency, as shown in Figure 22, such that the
switching frequency decreases as load decreases. In
heavy load conditions, the switching frequency is
65KHz. Once VFB decreases below VFB-N (2.2V), the
PWM frequency starts to linearly decrease from 65KHz
to 22.5kHz to reduce the switching losses. As VFB
decreases below VFB-G (2.1V), the switching frequency
is fixed at 22.5kHz and FAN6862 enters “deep” green
mode, where the operating current decreases to 2.5mA
(maximum), further reducing the standby power
consumption. As VFB decreases below VFB-ZDC (1.7V),
FAN6862 enters burst-mode operation. When VFB drops
below VFB-ZDC, FAN6862 stops switching and the output
voltage starts to drop, which causes the feedback
voltage to rise. Once VFB rises above VFB-ZDC, switching
resumes. Burst mode alternately enables and disables
switching, thereby reducing switching loss in standby
mode, as shown in Figure 23.

Open-Loop / Over-Load Protection (OLP)
When the upper branch of the voltage divider for the
shunt regulator (KA431 shown) is broken, as shown in
Figure 26, no current flows through the opto-coupler
transistor, which pulls up the feedback voltage to 5.2V.
Self-protective functions include VDD Over-Voltage
Protection (OVP), Open-Loop / Overload Protection
(OLP), Over-Current Protection (OCP), Short-Circuit
Protection, and Over-Temperature Protection (OTP).
OLP, OCP, and SCP are auto-restart mode protections;
while OVP and OTP are latch-mode protections.
When the feedback voltage is above 4.6V longer than
56ms, OLP is triggered. This protection is also triggered
when the SMPS output drops below the nominal value
longer than 56ms due to the overload condition.
Auto-Restart Mode Protection: Once a fault condition
is detected, switching is terminated and the MOSFET
remains off. This causes VDD to fall because no more
power is delivered from auxiliary winding. When VDD
falls to VDD-OFF (8.5V), the protection is reset and the
operating current reduces to startup current, which
causes VDD to rise. FAN6862 resumes normal operation
when VDD reaches VDD-ON (16V). In this manner, the
auto-restart can alternately enable and disable the
switching of the MOSFET until the fault condition is
eliminated (see Figure 25).
Latch-Mode Protection: Once this protection is
triggered, switching is terminated and the MOSFET
remains off. The latch is reset only when VDD is
discharged below 4V by unplugging AC power line.

VDD Over-Voltage Protection (OVP)
VDD over-voltage protection prevents IC damage caused
by over voltage on the VDD pin. The OVP is triggered
when VDD reaches 25V. A debounce time (typically
30µs) prevents false triggering by switching noise.

Over-Temperature Protection (OTP)
The OTP circuit is composed of current source and
voltage comparators. Typically, an NTC thermistor is
connected between the RT and GND pins. Once the
voltage of this pin drops below a threshold of 1.0V,
PWM output is disabled after tDOTP debounce time. If
this pin drops below 0.7V, it triggers the latch-off
protection immediately after tDOTP2 debounce time.

Over-Current Protection (OCP)
FAN6862 has over-current protection thresholds. It is
for pulse-by-pulse current limit, which turns off MOSFET
for the remainder of the switching cycle when the
sensing voltage of MOSFET drain current reaches the
threshold. The other threshold is for the over-current
protection, which shuts down the MOSFET gate when
the sensing voltage of MOSFET drain current is above
the threshold longer than the shutdown delay (56ms).

Leading-Edge Blanking (tLEB)
FAN6862 has saw-limiter for pulse-by-pulse current
limit, which guarantees almost constant power limit over
different line voltages of universal input range.
Each time the power MOSFET is switched on, a turn-on
spike occurs across the sense-resistor caused by
primary-side capacitance and secondary-side rectifier
reverse recovery. To avoid premature termination of the
switching pulse, a leading-edge blanking time is built in.
During this blanking period (360ns), the PWM
comparator is disabled and cannot switch off the gate
driver. Thus, RC filter with a small RC time constant is
enough for current sensing.
The conventional pulse-by-pulse current limiting
scheme has a constant threshold for current limit
comparator, which results in a higher power limit for
high line voltage. FAN6862 has a sawtooth current limit
threshold that increases progressively within a switching
cycle, which provides lower current limit for high line
and makes the actual power limit level almost constant
over different line voltages of universal input range, as
shown in Figure 27.

FAN6862 • Rev. 1.0.1
The FAN6862 has an internal soft-start circuit that
increases pulse-by-pulse current-limit comparator
inverting input voltage slowly after it starts. The typical
soft-start time is 4ms. The pulsewidth to the power
MOSFET is progressively increased to establish the
correct working conditions for transformers, rectifier
diodes, and capacitors. The voltage on the output
capacitors is progressively increased with the intention
of smoothly establishing the required output voltage. It
also helps prevent transformer saturation and reduces
the stress on the secondary diode during startup.
