Overview
FSFR-US Series — Fairchild Power Switch (FPS™) for Half-Bridge Resonant Converter May 2010 FSFR-US Series — Fairchild Power Switch (FPS™) for Half-Bridge Resonant Converters Features ƒ ƒ ƒ ƒ ƒ ƒ ƒ Variable Frequency Control with 50% Duty Cycle for Half-Bridge Resonant Converter Topology High Efficiency through Zero Voltage Switching (ZVS) Internal UniFET™s with Fast-Recovery Type Body Diode Fixed Dead Time (350ns) Optimized for MOSFETs Up to 300kHz Operating Frequency Auto-Restart Operation for All Protections with An External LVCC Protection Functions: Over-Voltage Protection (OVP), Over-Current Protection (OCP), Abnormal Over-Current Protection (AOCP), Internal Thermal Shutdown (TSD) Description The FSFR -US seri es a re a high ly inte grated p ower switches de signed for high-efficiency ha lf-bridge resonant co nverters.
O ffering ev erything ne cessary to build a reliable and robust resonant converter, the FSFRUS seri es si mplifies de signs and improves prod uctivity, while improv ing perf ormance.
T he FSFR -US serie s combines power MOSFETs with fast-recovery type body diodes, a high-side gate-drive circuit, an accurate current controlled oscillator, frequency limit circuit, soft-start, and built-in pr otection fu nctions.
T he high- side gat e-drive circuit has a common-mode noise cancellation capability, which gu arantees st able o peration w ith ex cellent noise immunity.
The fast-recovery body diode of the MOSFETs improves rel iability aga inst abn ormal ope ration conditions, w hile minimizing the e ffect of the rev erse recovery.
U sing th e z ero-voltage-switching ( ZVS) technique dramatically reduces the switching losses and efficiency i s significantly i mproved.
T he ZVS also reduces the sw itching no ise noticeably, w hich al lows a small-sized Electromagnetic Interference (EMI) filter.
The FSFR-US series can be applied to various resonant converter to pologies such as ser ies re sonant, para llel resonant, and LLC resonant converters.
