SMPS Power Switch for Charger, 0.4A, 650V, 8DIP/8LSOP
TM FSQ211 ⎯ Green Mode Fairchild Power Switch (FPS ) April 2007 FSQ211 TM Green Mode Fairchild Power Switch (FPS ) Features Description The FSQ211 consists of an integrated Pulse Width ƒ Internal Avalanche-Rugged SenseFET Modulator (PWM) and SenseFET, specifically designed ƒ Precision Fixed Operating Frequency (67KHz) for high-performance, off-line Switch Mode Power Supplies (SMPS) with minimal external components. ƒ Burst-Mode Operation This device is an integrated high-voltage power ƒ Internal Start-up Circuit switching regulator that combines a VDMOS SenseFET ƒ Pulse-by-Pulse Current Limiting with a voltage mode PWM control block. The integrated PWM controller features include a fixed oscillator, Under ƒ Overload Protection (OLP) Voltage Lockout (UVLO) protection, Leading Edge ƒ Internal Thermal Shutdown Function (TSD) Blanking (LEB), an optimized gate turn-on/turn-off driver, Thermal Shutdown (TSD) protection, and ƒ Auto-Restart Mode temperature compensated precision-current sources for ƒ Under-Voltage Lockout (UVLO) with Hysteresis loop compensation and fault protection circuitry. ƒ Built-in Soft-Start When compared to a discrete MOSFET and controller or ƒ Secondary-Side Regulation RCC switching converter solution, the FSQ211 device reduces total component count and design size and weight, while increasing efficiency, productivity, and Applications system reliability. This device provides a basic platform well suited for cost-effective flyback converters. ƒ Charger & Adapter for Mobile Phone, PDA, & MP3 ƒ Auxiliary Power for White Goods, PC, C-TV, & Monitor Related Application Notes ƒ AN-4137 Design Guidelines for Off-line Flyback Converters using FPS™ ƒ AN-4141 Troubleshooting and Design Tips for Fairchild Power Switch (FPS™) Flyback Applications ƒ AN-4147 Design Guidelines for RCD Snubber of Flyback ƒ AN-4134Design Guidelines for Off-line Forward Converters using FPS™ ƒ AN-4138Design Considerations for Battery Charger Using Green Mode Fairchild Power Switch (FPS™) Ordering Information Part Number Package Top Mark BV f R DSS OSC DS(ON) FSQ211 8DIP Q211 650V 67KHz 18Ω FSQ211L 8LSOP Q211L 650V 67KHz 18Ω TM FPS is a trademark of © 2007 FSQ211 Rev. 1.0.0
