TOP104YAI Datasheet (Power Integrations Inc.) - Three-terminal Off-line PWM Switch

TOP104YAI, Three-terminal Off-line PWM Switch

The TOPSwitch family implements, with only three pins, all functions necessary for an off-line switched mode control system: high voltage N-channel power MOSFET with controlled turn-on gate driver, voltage mode PWM controller with integrated 100 kHz oscillator, high voltage start-up bias circuit, ba

® TOP100-4 TOPSwitch® Family Three-terminal Off-line PWM Switch Product Highlights Low Cost Replacement for Discrete Switchers 20 to 50 fewer components - cuts cost, increases reliability Source-connected tab and Controlled MOSFET turn-on reduce EMI and EMI filter costs Allows for a 50% smaller and lighter solution Cost competitive with linears above 5 W Up to 90% Efficiency in Flyback Topology Built-in start-up and current limit reduce DC losse
