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

Built-in Soft-Start: 15ms
Description
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), 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.

Description
SenseFET Drain.
High-voltage power SenseFET drain connection.
Ground.
This pin is the control ground and the SenseFET source.
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.
No Connection.
Startup.
This pin is connected directly, or through a resistor, to the high-voltage DC link.
At startup, the internal high-voltage current source supplies internal bias and charges the
external capacitor connected to the V
CC
pin. Once V
CC
reaches 12V, the internal current
source (I
CH
) is disabled.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.
