FSQ0465RSLDTU Product details

Description
A Quasi-Resonant Converter (QRC) generally shows lower EMI and higher power conversion efficiency than a conventional hard-switched converter with a fixed switching frequency. The FSQ-series is an integrated Pulse-Width Modulation (PWM) controller and SenseFET specifically designed for quasi-resonant operation and Alternating Valley Switching (AVS). 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 a loop compensation, and self-protection circuitry. Compared with a discrete MOSFET and PWM controller solution, the FSQ-series can reduce total cost, component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability. This device provides a basic platform for cost-effective designs of quasi-resonant switching flyback converters.

Features
■ Optimized for Quasi-Resonant Converters (QRC)
■ Low EMI through Variable Frequency Control and AVS (Alternating Valley Switching)
■ High-Efficiency through Minimum Voltage Switching
■ Narrow Frequency Variation Range over Wide Load and Input Voltage Variation
■ Advanced Burst-Mode Operation for Low Standby Power Consumption
■ Simple Scheme for Sync Voltage Detection
■ 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)
■ Under-Voltage Lockout (UVLO) with Hysteresis
■ Internal Startup Circuit
■ Internal High-Voltage Sense FET (650V)
■ Built-in Soft-Start (17.5ms)

Applications
■ Power Supply for LCD TV and Monitor, VCR, SVR, STB, and DVD & DVD Recorder
■ Adapter
