Product Summary

The FSQ0365RN is a green mode fairchild power switch. 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 with minimal external components.

Parametrics

FSQ0365RN absolute maximum ratings: (1)Vstr Vstr Pin Voltage: 500 V; (2)VDS Drain Pin Voltage: 650 V; (3)VCC Supply Voltage: 20 V; (4)VFB Feedback Voltage Range: -0.3, 9.0 V; (5)VSync Sync Pin Voltage: -0.3, 9.0 V; (6)IDM Drain Current Pulsed(6): 12A; (7)PD Total Power Dissipation: 1.5 W.

Features

FSQ0365RN features: (1)Optimized for Quasi Resonant Converter (QRC); (2)Low EMI through Variable Frequency Control and Inherent Frequency Modulation; (3)High Efficiency through Minimum Voltage Switching; (4)Narrow Frequency Variation Range over Wide Load and Input Voltage Variation; (5)Advanced Burst Mode Operation for Low Standby Power Consumption; (6)Pulse by Pulse Current Limit. The FSQ0365RN applications are: (1)Power Supply for DVP Player and DVD Recorder; (2)Power supply for Set-Top Box; (3)Adapter; (4)Auxiliary Power Supply for PC, LCD TV, and PDP TV.
