I have similar design question related to one post such as LM5117: How to implement a pulsed constant current supply for driving laser diodes? - Power management forum - Power management - TI E2E support forums
If I want to 'dynamically' control the output current at 3 different levels as listed for example. What would be the simplest way of doing so? Would something like this work?
What if I have options to add parallel resistors to the RFBbottom resistor and controlled the FETs with GPIOs from a MCU (for example). By default, the FETs are off and say I have output current set at 10mA. If I want 1A, I just turn on the next resistor and if I want 3.5A, I just turn on the next resistor. Would this work?
thank you.
