3521J

UTC 3521J PWM controller is designed for switching mode power supply for PCs etc. It provides all the functions similar to combinations of industrial 494 plus 3510 circuits.

The UTC 3521J has four features.(1) Over-voltage protection for 3.3V, 5V and 12V with delay.(2) Under-voltage detection for 3.3V, 5V and 12V with delay.(3) Remote ON/OFF function.(4) Power good circuitry for PCs.The UTC 3521 has some absolute maximum ratings.(1) The parameter is supply voltagle,the symbol is Vcc,the rating is 5.5,the unit is V.(2) The parameter is drain output voltage,the symbol is Vcc1,Vcc2,the rating is 5.5,the unit is V. (3) The parameter is drain output current,the symbol is Icc1,Icc2,the rating is 200,the unit is mA.(4) The parameter is power dissipation,the symbol is PD,the rating is 200,the unit is mW.(5) The parameter is operating temperature,the symbol is Topr,the rating is -10 to +70,the unit is .(6) The parameter is storage temperature,the symbol is Tstg,the rating is -65 to +150,the unit is .
