FSL117MRIN

Features Description  Advanced Soft Burst Mode for Low Standby Pow er and Low Audible Noise  Random Frequency Fluctuation (RFF) for Low EMI  Under 50 mW Standby Pow er Consumption at 265 V AC, No-load Condition w ith Burst Mode  Pulse-by-Pulse Current Limit  Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over-Current Protection (AOCP), Internal Thermal Shutdow n (TSD) w ith Hysteresis, Output-Short Protection (OSP), Line Over-Voltage Protection (LOVP), and Under-Voltage Lockout (UVLO) w ith Hysteresis  Low Operating Current (0.4 mA) in Burst Mode  Internal Startup Circuit  Internal Avalanche-Rugged 700 V SenseFET  Built-in Soft-Start: 15 ms  Auto-Restart Mode The FSL117MRIN is an integr ated Puls e Width Modulation ( PWM) controller and 700 V Sens eFET specifically des igned for offline Sw itched- Mode Pow er Supplies ( SMPS) w ith minimal external c omponents. The PWM controller includes an integrated fixedfrequency oscillator , Line Over-Voltage Protection (LOV P) , Under-Voltage Lockout ( UVLO), LeadingEdge Blanking (LEB) , optimized gate driver, internal soft-start, temperatur e-compensated prec ise curr ent sources for loop compensation, and self-protection circuitry. Compar ed w ith a discrete MOSFET and PWM controller solution, the FSL117MRIN can reduce total cost, component count, size, and w eight; w hile simultaneously increasing efficiency, productiv ity, and system reliability. This dev ice pr ovides a bas ic platfor m for cost-effective design of a flyback converter. Applications  Pow er Supply for Home Appliances, LCD Monitors, STBs, and DVD Players Ordering Information Output Power Table (2) Part Number Package(1) FSL117MRIN 8-DIP Operating Current RDS(ON) Junction Limit (Max.)
