This paper presents a high‐performance LED lamp driver with an improved single‐stage Flyback configuration. A constant current control method is used to regulate the lamp current and brightness. A laboratory prototype has been built and tested. side MOSFET gate drive. The Two-Switch Flyback can be operated in either discontinuous or continu-ous conduction mode just like the Single-Switch Flyback converter. Conclusion By adding a high side MOSFET switch, the two-switch forward or flyback topology clamps the volt-age stress on each MOSFET switch to the input voltage. With the two- The circuit is only ran up to about 30V supply for the coil primary – high voltage rating of the mosfet is required to handle the flyback pulse. The power output is low, less than 50W. The NE555 IC drives the mosfet gate directly, and it’s duty cycle and frequency are controlled by trimmer resistors on the opposing side of the PCB.

This is Efficient flyback driver circuit, a good and fairly efficient flyback driver circuit. All parts can be obtained easily from Radio Shack, including the MOSFET. This single transistor flyback driver topology was created in response to achieve higher efficiency and higher output voltages from ordinary CRT television flybacks. As mentioned above this driver drives the flyback in flyback mode. What that means is that the mosfet is turned on by the timer, and current starts to flow through the primary winding. After some time the timer will turn off the mosfet again and the current will be forced to stop. As mentioned above this driver drives the flyback in flyback mode.
