(OLP), Over-Voltage Protection (OVP), Abnormal
Over-Current Protection (AOCP), Internal Thermal
Shutdown (TSD) with Hysteresis, Output Short
Protection (OSP), and Under-Voltage Lockout
(UVLO) with Hysteresis

Description
The FSGM0565R 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), Leading-
Edge 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.

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 turn-
on time. Such a steep current brings high-voltage
stress on drain of SenseFET when turned off. To
protect the device from such an 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 FSGM0565R 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.

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 FSGM0565R stops operation. The
FSGM0565R operates in auto-restart mode until the
temperature decreases to around 110°C, when
normal operation resumes.
5. Soft Burst-Mode Operation: To minimize power
dissipation in standby mode, the FSGM0565R 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 burst-
mode 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 FSGM0565R 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.
