Product Summary

The FSQ510 is a green mode fairchild power switch for quasi-resonant converter. 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 FSQ510(H) is an integrated Pulse-Width Modulation (PWM) controller and SenseFET specifically designed for quasi-resonant offline Switch Mode Power Supplies (SMPS) with minimal external components. Its applications include Cell Phone Chargers,ƒ Auxiliary Power Supplies for PC and White Goods.

Parametrics

FSQ510 absolute maximum ratings: (1)VSTR pin voltage: 700V; (2)drain pin voltage: 700V; (3)supply voltage: 20V; (4)feedback voltage range: -0.3 to 6.5V; (5)sync pin voltage: -0.3 to 6.5V; (6)operating junction temperature: 150℃; (7)operating ambient temperature: -25 to 85℃; (8)storage temperature: -55 to 150℃.

Features

FSQ510 features: (1)Uses a DMOS Integrated Power Switch; (2)Optimized for Quasi-Resonant Converter (QRC); (3)Low EMI through Variable Frequency Control and Inherent Frequency Modulation; (4)High Efficiency through Minimum Voltage Switching ƒ Extended Quasi-Resonant Switching for Wide Load Ranges; (5)Small Frequency Variation for Wide Load Ranges; (6)Advanced Burst-Mode Operation for Low Standby; (7)Power Consumption.
