Description

The TOP203YAI is designed as one kind of three-terminal off-line PWM switch device that has some points of features:(1)20 to 50 fewer components - cuts cost, increases reliability; (2)Source-connected tab and Controlled MOSFET turn-on reduce EMI and EMI filter costs; (3)Allows for a 50% smaller and lighter solution; (4)Cost competitive with linears above 5 W; (5)Built-in start-up and current limit reduce DC losses; (6)Low capacitance 700 V MOSFET cuts AC losses; (7)CMOS controller/gate driver consumes only 6 mW; (8)70% maximum duty cycle minimizes conduction losses; (9)Supported by many reference design boards; (10)Integrated PWM Controller and 700 V MOSFET in a; (11)industry standard three pin TO-220 package; (12)Only one external capacitor needed for compensation, bypass and start-up/auto-restart functions.

The absolute maximum ratings of the TOP203YAI can be summarized as:(1)Lead Temperature: 260 °C;(2)Operating Junction Temperature: -40 °C to 150 °C;(3)Storage Temperature: -65 °C to 150 °C;(4)Thermal Impedance: 70 or 2 °C/W;(5)control current: 100 mA;(6)control voltage: -0.3 V to 9 V;(7)drain voltage: -0.3 to +700 V.etc. If you want to know more information about the TOP203YAI, please download the datasheet in www.seekic.com or www.chinaicmart.com .
