FSQ0170RNA, FSQ0270RNA, FSQ0370RNA  
Green Mode Fairchild Power Switch (FPS™)  
Features  
Description  
„ Internal Avalanche Rugged 700V SenseFET  
„ Consumes only 0.8W at 230 VAC & 0.5W Load with  
Burst-Mode Operation  
„ Precision Fixed Operating Frequency, 100kHz  
„ Internal Start-up Circuit and Built-in Soft-Start  
The FSQ0170RNA, FSQ0270RNA, FSQ0370RNA  
consists of an integrated current mode Pulse Width  
Modulator (PWM) and an avalanche-rugged 700V Sense  
FET. It is specifically designed for high-performance off-  
line Switch Mode Power Supplies (SMPS) with minimal  
external components. The integrated PWM controller  
features include: a fixed-frequency generating oscillator,  
Under-Voltage Lockout (UVLO) protection, Leading  
Edge Blanking (LEB), an optimized gate turn-on/turn-off  
driver, Thermal Shutdown (TSD) protection, and  
temperature compensated precision current sources for  
loop compensation and fault protection circuitry.  
„ Pulse-by-Pulse Current Limiting and Auto-Restart  
Mode  
„ Over-Voltage Protection (OVP), Overload Protection  
(OLP), Internal Thermal Shutdown Function (TSD)  
„ Under-Voltage Lockout (UVLO)  
„ Low Operating Current (3mA)  
„ Adjustable Peak Current Limit  
Compared to a discrete MOSFET and controller or RCC  
switching converter solution, the FSQ0170RNA,  
FSQ0270RNA, FSQ0370RNA reduces total component  
count, design size, and weight while increasing  
efficiency, productivity, and system reliability. These  
devices provide a basic platform that is well suited for the  
design of cost-effective flyback converters, as in PC  
auxiliary power supplies.  
Applications  
„ Auxiliary Power Supply for PC and Server  
„ SMPS for VCR, SVR, STB, DVD & DVCD Player,  
Printer, Facsimile & Scanner  
„ Adapter for Camcorder
