Description

The FSL117MRIN is an integrated Pulse Width Modulation (PWM) controller and 700V SenseFET specifically designed for offline Switched-Mode Power Supplies (SMPS) with minimal external components. The PWM controller includes an integrated fixedfrequency oscillator, Line Over-Voltage Protection (LOVP), 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 FSL117MRIN can reduce total cost, component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability. This device provides a basic platform for cost-effective design of a flyback converter.

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

CC

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 7V, the overload protection triggers, which shuts down the FPS.

Line Over-Voltage Input. This pin is the input pin of line voltage. The voltage, which is

divided by resistors, is input of this pin. If this pin voltage higher than V

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

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.
