Description
The FSDM0565R is an integrated Pulse Width Modulator
(PWM) and Sense FET specifically designed for high
performance offline Switch Mode Power Supplies (SMPS)
with minimal external components. This device is an
integrated high voltage power switching regulator which
combine an avalanche rugged Sense FET with a current mode
PWM control block. The PWM controller includes integrated
fixed frequency oscillator, under voltage lockout, leading edge
blanking (LEB), optimized gate driver, internal soft start,
temperature compensated precise current sources for a loop
compensation and self protection circuitry. Compared with
discrete MOSFET and PWM controller solution, it can reduce
total cost, component count, size and weight simultaneously
increasing efficiency, productivity, and system reliability. This
device is a basic platform well suited for cost effective
designs of flyback converters.

Drain
This pin is the high voltage power Sense FET drain. It is designed to drive the
transformer directly.
2
GND
This pin is the control ground and the Sense FET source.
Vcc
This pin is the positive supply voltage input. During start up, the power is supplied by an internal high voltage current source that is connected to the Vstr pin.
When Vcc reaches 12V, the internal high voltage current source is disabled and
the power is supplied from the auxiliary transformer winding.
4
Vfb
This pin is internally connected to the inverting input of the PWM comparator.
The collector of an opto-coupler is typically tied to this pin. For stable operation,
a capacitor should be placed between this pin and GND. If the voltage of this pin
reaches 6.0V, the over load protection is activated resulting in shutdown of the
FPSTM.

Vstr
This pin is connected directly to the high voltage DC link. At startup, the internal
high voltage current source supplies internal bias and charges the external capacitor that is connected to the Vcc pin. Once Vcc reaches 12V, the internal current source is disabled.

Functional Description
1. Startup : In previous generations of Fairchild Power
Switches (FPSTM) the Vcc pin had an external start-up
resistor to the DC input voltage line. In this generation the
startup resistor is replaced by an internal high voltage current
source. At startup, an internal high voltage current source
supplies the internal bias and charges the external capacitor
(Cvcc) that is connected to the Vcc pin as illustrated in figure
4. When Vcc reaches 12V, the FPSTM begins switching and
the internal high voltage current source is disabled. Then, the
FPSTM continues its normal switching operation and the
power is supplied from the auxiliary transformer winding
unless Vcc goes below the stop voltage of 8V.

2.1 Pulse-by-pulse current limit: Because current mode
control is employed, the peak current through the Sense FET
is limited by the inverting input of PWM comparator (Vfb*)
as shown in figure 5. Assuming that the 0.9mA current
source flows only through the internal resistor (2.5R +R= 2.8
kΩ), the cathode voltage of diode D2 is about 2.5V. Since D1
is blocked when the feedback voltage (Vfb) exceeds 2.5V,
the maximum voltage of the cathode of D2 is clamped at this
voltage, thus clamping Vfb*. Therefore, the peak value of
the current through the Sense FET is limited.
2.2 Leading edge blanking (LEB) : At the instant the
internal Sense FET is turned on, there usually exists a high
current spike through the Sense FET, caused by primary-side
capacitance and secondary-side rectifier reverse recovery.
Excessive voltage across the Rsense resistor would lead to
incorrect feedback operation in the current mode PWM
control. To counter this effect, the FPSTM employs a leading
edge blanking (LEB) circuit. This circuit inhibits the PWM
comparator for a short time (TLEB) after the Sense FET is
turned on.

2. Feedback Control : FSDM0565R employs current mode
control, as shown in figure 5. An opto-coupler (such as the
H11A817A) and shunt regulator (such as the KA431) are
typically used to implement the feedback network.
Comparing the feedback voltage with the voltage across the
Rsense resistor plus an offset voltage makes it possible to
control the switching duty cycle. When the reference pin
voltage of the KA431 exceeds the internal reference voltage
of 2.5V, the H11A817A LED current increases, thus pulling
down the feedback voltage and reducing the duty cycle. This
event typically happens when the input voltage is increased
or the output load is decreased.
3. Protection Circuit : The FSDM0565R has several self
protective functions such as over load protection (OLP),
abnormal over current protection (AOCP), over voltage
protection (OVP) and thermal shutdown (TSD). Because
these protection circuits are fully integrated into the IC
without external components, the reliability can be improved
without increasing cost. Once the fault condition occurs,
switching is terminated and the Sense FET remains off. This
causes Vcc to fall. When Vcc reaches the UVLO stop
voltage, 8V, the protection is reset and the internal high
voltage current source charges the Vcc capacitor via the Vstr
pin. When Vcc reaches the UVLO start voltage,12V, the
FPSTM resumes its normal operation. In this manner, the
auto-restart can alternately enable and disable the switching
of the power Sense FET until the fault condition is
eliminated (see figure 6).

3.1 Over Load Protection (OLP) : Overload is defined as
the load current exceeding a pre-set level due to an
unexpected event. In this situation, the protection circuit
should be activated in order to protect the SMPS. However,
even when the SMPS is in the normal operation, the over
load protection circuit can be activated during the load
transition. In order to avoid this undesired operation, the over
load protection circuit is designed to be activated after a
specified time to determine whether it is a transient situation
or an overload situation. Because of the pulse-by-pulse
current limit capability, the maximum peak current through
the Sense FET is limited, and therefore the maximum input
power is restricted with a given input voltage. If the output
consumes beyond this maximum power, the output voltage
(Vo) decreases below the set voltage. This reduces the
current through the opto-coupler LED, which also reduces
the opto-coupler transistor current, thus increasing the
feedback voltage (Vfb). If Vfb exceeds 2.5V, D1 is blocked
and the 3.5uA current source starts to charge CB slowly up to
Vcc. In this condition, Vfb continues increasing until it
reaches 6V, when the switching operation is terminated as
shown in figure 7. The delay time for shutdown is the time
required to charge CB from 2.5V to 6.0V with 3.5uA. In
general, a 10 ~ 50 ms delay time is typical for most
applications.

3.2 Abnormal Over Current Protection (AOCP) : Even
though the FPSTM has OLP (Over Load Protection) and
current mode PWM feedback, these are not enough to protect
the FPSTM when a secondary side diode short or a
transformer pin short occurs. The FPSTM has an internal
AOCP (Abnormal Over Current Protection) circuit as shown
in figure 8. When the gate turn-on signal is applied to the
power Sense FET, the AOCP block is enabled and monitors
the current through the sensing resistor. The voltage across
the resistor is then compared with a preset AOCP level. If the
sensing resistor voltage is greater than the AOCP level for
longer than 300ns, the reset signal is applied to the latch,
resulting in the shutdown of SMPS.

3.3 Over voltage Protection (OVP) : If the secondary side
feedback circuit were to malfunction or a solder defect
caused an open in the feedback path, the current through the
opto-coupler transistor becomes almost zero. Then, Vfb
climbs up in a similar manner to the over load situation,
forcing the preset maximum current to be supplied to the
SMPS until the over load protection is activated. Because
more energy than required is provided to the output, the
FSDM0565R
output voltage may exceed the rated voltage before the over
load protection is activated, resulting in the breakdown of the
devices in the secondary side. In order to prevent this
situation, an over voltage protection (OVP) circuit is
employed. In general, Vcc is proportional to the output
voltage and the FPSTM uses Vcc instead of directly
monitoring the output voltage. If VCC exceeds 19V, an OVP
circuit is activated resulting in the termination of the
switching operation. In order to avoid undesired activation of
OVP during normal operation, Vcc should be designed to be
below 19V.

3.4 Thermal Shutdown (TSD) : The Sense FET and the
control IC are built in one package. This makes it easy for
the control IC to detect the heat generation from the Sense
FET. When the temperature exceeds approximately 150°C,
the thermal shutdown is activated.
4. Soft Start : The FPSTM has an internal soft start circuit
that increases PWM comparator inverting input voltage
together with the Sense FET current slowly after it starts up.
The typical soft start time is 10msec, The pulse width to the
power switching device is progressively increased to
establish the correct working conditions for transformers,
inductors, and capacitors. The voltage on the output
capacitors is progressively increased with the intention of
smoothly establishing the required output voltage. It also
helps to prevent transformer saturation and reduce the stress
on the secondary diode during startup.

Figure 9. Waveforms of burst operation
5. Burst operation : In order to minimize power dissipation
in standby mode, the FPSTM enters burst mode operation.
As the load decreases, the feedback voltage decreases. As
shown in figure 9, the device automatically enters burst
mode when the feedback voltage drops below
VBURL(500mV). At this point switching stops and the
output voltages start to drop at a rate dependent on standby
current load. This causes the feedback voltage to rise. Once
it passes VBURH(700mV) switching resumes. The feedback
voltage then falls and the process repeats. Burst mode
operation alternately enables and disables switching of the
power Sense FET thereby reducing switching loss in
Standby mode.

Key Design Notes
• Resistors R102 and R105 are employed to prevent start-up at low input voltage. After startup, there is no power loss in these
resistors since the startup pin is internally disconnected after startup.
• The delay time for over load protection is designed to be about 50ms with C106 of 47nF. If a faster triggering of OLP is
required, C106 can be reduced to 10nF.
• Zener diode ZD102 is used for a safety test such as UL. When the drain pin and feedback pin are shorted, the zener diode
fails and remains short, which causes the fuse (F1) blown and prevents explosion of the opto-coupler (IC301). This zener
diode also increases the immunity against line surge.
