Features
Description
ƒ Soft Burst-Mode Operation for Low Standby Power
The FSGM0465RB is an integrated Pulse Width
Modulation (PWM) controller and SenseFET specifically
designed for offline Switch-Mode Power Supplies
(SMPS) with minimal external components. The PWM
controller includes an integrated fixed-frequency
oscillator, Under-Voltage Lockout (UVLO), LeadingEdge Blanking (LEB), optimized gate driver, internal
soft-start, temperature-compensated precise current
sources for loop compensation, and self-protection
circuitry. Compared with a discrete MOSFET and PWM
controller solution, the FSGM series can reduce total
cost, component count, size, and weight; while
simultaneously increasing efficiency, productivity, and
system reliability. This device provides a basic platform
suited for cost-effective design of a flyback converter.

Description
Power Supply. This pin is the positive supply input, which provides the internal operating
current for both startup and steady-state operation.
Feedback. 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 6V, the
overload protection triggers, which shuts down the FPS.

3. Feedback Control: This device employs currentmode control, as shown in Figure 18. An opto-coupler
(such as the FOD817) 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 makes it possible to
control the switching duty cycle. When the reference pin
voltage of the shunt regulator exceeds the internal
reference voltage of 2.5V, the opto-coupler LED current
increases, pulling down the feedback voltage and
reducing drain current. This typically occurs when the
input voltage is increased or the output load is decreased.
1. Startup: At startup, an internal high-voltage current
source supplies the internal bias and charges the
external capacitor (CVcc) connected to the VCC pin, as
illustrated in Figure 17. When VCC reaches 12V, the
FSGM0465RB begins switching and the internal highvoltage current source is disabled. The FSGM0465RB
continues normal switching operation and the power is
supplied from the auxiliary transformer winding unless
VCC goes below the stop voltage of 7.5V.
3.1 Pulse-by-Pulse Current Limit: Because currentmode control is employed, the peak current through
the SenseFET is limited by the inverting input of PWM
comparator (VFB*), as shown in Figure 18. Assuming
that the 210μA current source flows only through the
internal resistor (3R + R =11.6kΩ), the cathode
voltage of diode D2 is about 2.4V. Since D1 is
blocked when the feedback voltage (VFB) exceeds
2.4V, the maximum voltage of the cathode of D2 is
clamped at this voltage. Therefore, the peak value of
the current through the SenseFET is limited.
3.2 Leading-Edge Blanking (LEB): At the instant the
internal SenseFET is turned on, a high-current spike
usually occurs through the SenseFET, caused by
primary-side capacitance and secondary-side rectifier
reverse recovery. Excessive voltage across the
RSENSE resistor leads to incorrect feedback operation
in the current mode PWM control. To counter this
effect, the FSGM0465RB employs a leading-edge
blanking (LEB) circuit. This circuit inhibits the PWM
comparator for tLEB (300ns) after the SenseFET is
turned on.
Figure 17. Startup Block
2. Soft-Start: The FSGM0465RB has an internal softstart circuit that increases PWM comparator inverting
input voltage, together with the SenseFET current,
slowly after it starts. The typical soft-start time is 15ms.
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 to smoothly establish the required output
voltage. This helps prevent transformer saturation and
reduces stress on the secondary diode during startup.

Figure 20. Overload Protection
4.2 Abnormal Over-Current Protection (AOCP):
When the secondary rectifier diodes or the
transformer pins are shorted, a steep current with
extremely high di/dt can flow through the SenseFET
during the minimum turn-on time. Even though the
FSGM0465RB has overload protection, it is not
enough to protect the FSGM0465RB in that abnormal
case; since severe current stress is imposed on the
SenseFET until OLP is triggered. The FSGM0465RB
internal AOCP circuit is shown in Figure 21. When
the gate turn-on signal is applied to the power
SenseFET, the AOCP block is enabled and monitors
the current through the sensing resistor. The voltage
across the resistor is compared with a preset AOCP
level. If the sensing resistor voltage is greater than
the AOCP level, the set signal is applied to the S-R
latch, resulting in the shutdown of the SMPS.
FSGM0465RB — Green-Mode Fairchild Power Switch (FPS™)
increasing until it reaches 6.0V, when the switching
operation is terminated, as shown in Figure 20. The
delay time for shutdown is the time required to charge
CFB from 2.4V to 6.0V with 3.3µA. A 25 ~ 50ms delay
is typical for most applications. This protection is
implemented in auto-restart mode.
4. Protection Circuits: The FSGM0465RB has several
self-protective functions, such as Overload Protection
(OLP), Abnormal Over-Current Protection (AOCP),
Output-Short Protection (OSP), Over-Voltage Protection
(OVP), and Thermal Shutdown (TSD). All the
protections are implemented as auto-restart. Once the
fault condition is detected, switching is terminated and
the SenseFET remains off. This causes VCC to fall.
When VCC falls to the Under-Voltage Lockout (UVLO)
stop voltage of 7.5V, the protection is reset and the
startup circuit charges the VCC capacitor. When VCC
reaches the start voltage of 12.0V, the FSGM0465RB
resumes normal operation. If the fault condition is not
removed, the SenseFET remains off and VCC drops to
stop voltage again. In this manner, the auto-restart can
alternately enable and disable the switching of the
power SenseFET until the fault condition is eliminated.
Because these protection circuits are fully integrated
into the IC without external components, the reliability is
improved without increasing cost.
Figure 19. Auto-Restart Protection Waveforms
4.1 Overload Protection (OLP): Overload is defined
as the load current exceeding its normal level due to
an unexpected abnormal event. In this situation, the
protection circuit should trigger to protect the SMPS.
However, even when the SMPS is in normal
operation, the overload protection circuit can be
triggered during the load transition. To avoid this
undesired operation, the overload protection circuit is
designed to trigger only after a specified time to
determine whether it is a transient situation or a true
overload situation. Because of the pulse-by-pulse
current limit capability, the maximum peak current
through the SenseFET is limited and, therefore, the
maximum input power is restricted with a given input
voltage. If the output consumes more than this
maximum power, the output voltage (VOUT) 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 2.4V, D1 is
blocked and the 3.3µA current source starts to charge
CFB slowly up. In this condition, VFB continues

5. Soft Burst-Mode Operation: To minimize power
dissipation in standby mode, the FSGM0465RB enters
burst-mode operation. As the load decreases, the
feedback voltage decreases. As shown in Figure 23,
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. At this point, the
drain current peak increases gradually. This soft burstmode can reduce audible noise during burst-mode
operation. The feedback voltage then falls and the
process repeats. Burst-mode operation alternately
enables and disables switching of the SenseFET,
thereby reducing switching loss in standby mode.
Figure 22. Output-Short Protection
4.4 Over-Voltage Protection (OVP): If the
secondary-side feedback circuit malfunctions or a
solder defect causes an opening in the feedback
path, the current through the opto-coupler transistor
becomes almost zero. Then VFB climbs up in a similar
manner to the overload situation, forcing the preset
maximum current to be supplied to the SMPS until
the overload protection is triggered. Because more
energy than required is provided to the output, the
output voltage may exceed the rated voltage before
the overload protection is triggered, resulting in the
breakdown of the devices in the secondary side. To
prevent this situation, an OVP circuit is employed. In
general, the VCC is proportional to the output voltage
and the FSGM0465RB uses VCC instead of directly
monitoring the output voltage. If VCC exceeds 24.5V,
an OVP circuit is triggered, resulting in the
termination of the switching operation. To avoid
undesired activation of OVP during normal operation,
VCC should be designed to be below 24.5V.

FSGM0465RB — Green-Mode Fairchild Power Switch (FPS™)
4.5 Thermal Shutdown (TSD): The SenseFET and
the control IC on a die in one package makes it
easier for the control IC to detect the over
temperature of the SenseFET. If the temperature
exceeds ~140°C, the thermal shutdown is triggered
and the FSGM0465RB stops operation. The
FSGM0465RB operates in auto-restart mode until the
temperature decreases to around 110°C, when
normal operation resumes.
4.3. Output-Short Protection (OSP): If the output is
shorted, steep current with extremely high di/dt can
flow through the SenseFET during the minimum turnon time. Such a steep current brings high-voltage
stress on the drain of the SenseFET when turned off.
To protect the device from this abnormal condition,
OSP is included. It is comprised of detecting VFB and
SenseFET turn-on time. When the VFB is higher than
2V and the SenseFET turn-on time is lower than
1.2μs, the FSGM0465RB recognizes this condition as
an abnormal error and shuts down PWM switching
until VCC reaches VSTART again. An abnormal
condition output short is shown in Figure 22.

Key Design Notes:
1.
The delay time for overload protection is designed to be about 25ms with C105 (22nF). OLP time between 25ms
(22nF) and 50ms (43nF) is recommended.
2.
The SMD-type capacitor (C106) must be placed as close as possible to the VCC pin to avoid malfunction by
abrupt pulsating noises and to improve ESD and surge immunity. Capacitance between 100nF and 220nF is
recommended.
