Hello all,

I am new in this forum so pardon me for any mistake type in this project forum.

I am currently doing this project in powering a string of LEDs which have the output 24Vdc and approx 700mA. As I will be using an AC main power supply, I know that I will need to rectify it to DC before I can do anything. Furthermore, I will also need to power a micro-controller straight after the rectification. So the process is as follow:

AC main ------> Rectifier diode bridge (325Vdc) -------> Power up a 5V micro-controller as well as going to a POWER MOSFET (from calculation the duty cycle will have to be only 6% ) -------> BUCK converter ------->24Vdc to power the LED.

Can I know if this process is correct? Or will I have to use the mosfet to generate a high frequency voltage and use a high frequency transformer to step down the voltage? ( After PWM from MOSFET the voltage will be AC right?)

Thanks!
