FSL176MRT

FSL176MRT — Green-Mode Fairchild Power Switch (FPS™) August 2012 FSL176MRT Green-Mode Fairchild Power Switch (FPS™) Features  Advanced Soft Burst-Mode Operation for Low Standby Power and Low Audible Noise Description The F SL176MRT is an integrated Pulse W idth Modulation (PWM) controller and SenseFET specifically designed for offline Sw itched-Mode Power Supplies (SMPS) with minimal external components. T he PW M controller includes an in tegrated fixed-frequency oscillator, Under-Voltage Lockout (UVLO), LeadingEdge Blanking (LEB), optimized gate driver, internal soft-start, temperature-co mpensated precise current sources for loop compensation, and self-protection circuitry. Compared with a discrete MOSF ET and PW M controller solution, the F SL176MRT can reduce total cost, component count, size, and w eight; w hile simultaneously increasing efficiency , productivity , and system reliability. T his device provides a basic platform for cost-effective design of a flyback converter.  Random Frequency Fluctuation for Low EMI  Pulse-by-Pulse Current Limit  Various Protection Functions: 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  Low Operating Current (0.4mA) in Burst Mode  Internal Startup Circuit  Internal High-Voltage SenseFET: 650V  Built-in Soft-Start: 15ms  Auto-Restart Mode Ap...
