FSL137MRIN

FSL137MRIN — Green-Mode Fairchild Power Switch (FPS™) March 2013 FSL137MRIN Green-Mode Fairchild Power Switch (FPS™) Features  Advanced Soft Burst Mode for Low Standby Power and Low Audible Noise  Random Frequency Fluctuation (RFF) for Low EMI  Under 50 mW Standby Power Consumption at 265 VAC, No-load Condition with Burst Mode  Pulse-by-Pulse Current Limit  Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over-Current Protection (AOCP), Internal Thermal Shutdown (TSD) with Hysteresis, Output-Short Protection (OSP), and Under-Voltage Lockout (UVLO) with Hysteresis, Line Over-Voltage Protection (LOVP)  Low Operating Current (0.4 mA) in Burst Mode  Internal Startup Circuit  Internal High-Voltage SenseFET: 700 V  Built-in Soft-Start: 15 ms  Auto-Restart Mode Applications  Power Supply for Home Appliances, LCD Monitors, STBs, and DVD Players Description The FSL137MRIN is an integrated Pulse Width Modulation (PWM) controller and SenseFET specifically designed for offline Switched Mode Power Supplies (SMPS) with minimal external components. The PWM controller includes an integrated fixed-frequency oscillator, Line Over-Voltage Protection (LOVP), UnderVoltage Lockout (UVLO), Leading-Edge Blanking (LEB), optimized gate driver, internal soft-start, temperaturecompensated precise current sources for loop compensation, and self-protection circuitry. Compared with a discrete MOSFET and PWM controller solution, the FSL137MRIN reduces total cost, component c...
