Description
The TOP209/210 implements 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 oscillator, high voltage start-up bias circuit, bandgap derived reference, bias shunt regulator/error amplifier for loop pensation and fault protection circuitry. pared to discrete MOSFET and controller or self oscillating (RCC) switching converter solutions, a TOPSwitch...
