Description
The FSGM0565RB 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
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.

... V goes below the stop voltage of 7.5V. CC Figure 17. Startup Block 2. Soft-Start: The FSGM0565RB has an internal soft- start 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 ...

... SenseFET during the minimum turn-on time. Even though the FSGM0565RB has overload protection not enough to protect the FSGM0565RB in that abnormal case; since severe current stress is imposed on the SenseFET until OLP is triggered.

... To protect the device from this abnormal condition, OSP is included comprised of detecting V SenseFET turn-on time. When the V 2V and the SenseFET turn-on time is lower than 1.2μs, the FSGM0565RB recognizes this condition as an abnormal error and shuts down PWM switching until V reaches V ...
