Product overview

Overview

DescriptionA 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 (VSC)
• Low EMI through Variable Frequency Control and
•nherent 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
• Various Protection Functions: Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over-Current Protection (AOCP), Internal
Thermal Shutdown (TSD)
• Under-Voltage Lockout (UVLO) with Hysteresis
• Internal Start-up Circuit
• Internal High-Voltage SenseFET (650V)
• Built-in Soft-Start (15ms)Applications
• Power Supply for DVP Player and DVD Recorder, Set-Top Box
• Adapter
• Auxiliary Power Supply for PC, LCD TV, and PDP TV
