?2004 fairchild semiconductor corporation www.fairchildsemi.com rev.1.0.4 features ? quasi resonant converter controller ? internal burst mode controller for stand-by mode ? pulse by pulse current limiting ? over current latch protection ? over voltage protection (vcc: min. 27v) ? internal thermal shutdown function ? under voltage lockout ? internal high voltage sense fet ? auto-restart mode description the fairchild power switch(fps) product family is specially designed for an off-line smps with minimal external components. the fairchild power switch(fps) consists of a high voltage power sensefet and a current mode pwm ic. the integrated pwm controller includes the fixed oscillator, the under voltage lock out, the leading edge blanking, the optimized gate turn-on/turn-off driver, the thermal shut down protection, the over voltage protection, and the temperature compensated precision current sources for loop compensation and fault protection circuitry. compared to a discrete mosfet and a controller or a rcc switching converter solutions, a fairchild power switch(fps) can reduce the total number of components, design size, and weight, so it will improve efficiency, productivity, and system reliability. it has a basic platform well suited for cost-effective design in a quasi-resonant converter as a c-tv power supply. to-220f-5l 1. drain 2. gnd 3. v cc 4. feedback 5. sync internal block diagram rsense 3 1 2 4 vref internal bias s q r leb 450ns s qb r ro n rof f power on reset ovp olp 7.5v - + 30v vcc - + - + uvlo 15v/9v 5 burst mode 3.5v/1.25v r 2.5r - + - + offset thermal thermal thermal thermal shut down shut down shut down shut down s q r power reset delay 80ns 1v - + ocl 1v feedback feedback feedback feedback vcc vcc vcc vcc drain drain drain drain source source source source normal mode 4.6v/2.6v osc - + - + idelay ifb vref 11v on 12v off - + sync sync sync sync ron roff ka5Q0565RT fairchild power switch(fps) www.datasheet.in
