Product overview
Overview
The FSD146MRBN is an integrated Pulse Width Modulation (PWM) controller and SenseFET designed for offline Switch-Mode Power Supplies (SMPS) with minimal external components.
The PWM controller includes an integrated fixed-frequency oscillator, 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 FSD146MRBN can reduce total cost, component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability. This device provides a basic platform that is well suited for cost-effective design of a flyback converter.
Features
• Advanced Soft Burst-Mode Operation for Low Standby Power and Low Audible Noise
• 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 ModeApplications
• Power Supply for LCD Monitor, STB, and DVD Combination
