Hello everyone,
I need to make a dimmable buck converter. In practice, my requirement is to flash (<100Hz) a resistive load with variable duty.
The control signal is PWM from a microcontroller and the system is battery powered.
I searched the net but I didn't find a well-defined solution. What I wanted to ask is:
1) There are dc dc converter chips that have the PWM input to make the output flash?
2) How can I modify an existing buck converter scheme to add the PWM input?
3) Some converters have enable input, can I use this for PWM, could I have problems in the long run?
4) I saw that almost all LED drivers have this input, can I modify a driver LED to drive a pure resisitive load?
thanks in advance, FM
