FSQ321L規(guī)格書詳情
Description
A Valley Switching Converter 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 valley switching operation with minimal external components. The PWM controller includes an integrated fixed-frequency oscillator, under-voltage lockout, Leading-Edge Blanking (LEB), optimized gate driver, internal soft-start, temperature-compensated precise current sources for loop compensation, and self-protection circuitry.
Features
■ Optimized for Valley Switching Converter (VSC)
■ Low EMI through Variable Frequency Control and Inherent Frequency Modulation
■ 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
■ Pulse-by-Pulse Current Limit
■ Protection Functions: Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal OverCurrent Protection (AOCP), Internal Thermal Shutdown (TSD)
■ Under-Voltage Lockout (UVLO) with Hysteresis
■ Internal Startup Circuit
■ Internal High-Voltage SenseFET: 650V
■ Built-in Soft-Start: 15ms
Applications
■ Power Supplies for DVP Player, DVD Recorder, Set-Top Box
■ Adapter
■ Auxiliary Power Supply for PC, LCD TV, and PDP TV
