Howdy,
I'm constructing a Buck Converter and have decided to use the SG3525 chip for the control of the MOSFET switch. I am having a few issues getting info on how to set up the SG3525 for PWM.
The control interface will work by measuring the voltage and current at the output of the converter, sending this to the microcontroller, then the MC sending a voltage reference to the PWM circuitry to adjust the duty cycle.
Any help would be hugely appreciated.
