The FSL117MRIN is an integrated Pulse Width Modulation (PWM) Controller and 700V SenseFET designed for off-line Switch Mode Power Supplies (SMPS) with minimal external parts count. PWM controller includes integrated fixed frequency oscillator, line overvoltage protection (LOVP), undervoltage lockout (UVLO), leading edge spacing (LEB), optimized gate drivers, internal soft start, temperature compensation for loop compensation Accurate current source, and self-protection circuit. Compared to discrete MOSFET and PWM controller solutions, the FSL117MRIN reduces total cost, parts count, size and weight; while improving energy efficiency, productivity and system reliability. This device provides the basic platform for cost-effective design of flyback converters.
