8 / 23 page © 2008 Fairchild Semiconductor Corporation www.fairchildsemi.com FSQ0565RS/RQ Rev. 1.0.3 8 Comparison Between FSDM0x65RNB and FSQ-Series Differences Between FSQ0565RS and FSQ0565RQ Function FSDM0x65RE FSQ-Series FSQ-Series Advantages Operation Method Constant Frequency PWM Quasi-Resonant Operation ! Improved efficiency by valley switching ! Reduced EMI noise ! Reduced components to detect valley point EMI Reduction Frequency Modulation Reduced EMI Noise ! Valley Switching ! Inherent Frequency Modulation ! Alternate Valley Switching Hybrid Control CCM or AVS Based on Load and Input Condition ! Improves efficiency by introducing hybrid control Burst-Mode Operation Burst-Mode Operation Advanced Burst-Mode Operation ! Improved standby power by advanced burst-mode Strong Protections OLP, OVP OLP, OVP, OSP ! Improved reliability through precise OSP TSD 145°C without Hysteresis 140°C with 60°C Hysteresis ! Stable and reliable TSD operation ! Converter temperature range Function FSQ0565RS FSQ0565RQ Remark ILIM 2.25A 3.0A ! Lower current peak is suitable to reduce conduc- tion loss ! Higher current peak is suitable for handling higher power Over Voltage Protection VCC OVP (triggered by VCC voltage) Sync OVP (triggered by Sync voltage) ! Sync OVP is suitable when VCC voltage is pre reg- ulated. |
