This isn't suitable for this.
In general you do not do any high frequency modulation in the power supply, this is not the component for that.
You put your capacitors and the switching required where it's needed more or less the supply can be constant.
- rektide 6y agoWe can start the discussion on soldering irons, I guess. There seem to be two main strategies. I'm not super well versed on the pro's & cons of each. A lot of soldering irons use a resistive heating element. Dump current in, get heat. Higher end soldering irons tend to use high frequency inductive heating. Hakko has a write up here[1]. Agreed that for a switching supply, PPS isn't going to help a lot. For a resistive soldering iron, a PPS capable USB power source would be very helpful. All that's needed is a control loop, to monitor temperature & adjust the asked for input voltage and/or current. Honestly not sure what the Pinecil or the well known TS100 soldering iron are, resistive or RF inductive. It'd be great if they were RF inductive heating, & PPS wasn't helpful, as the much finer control would be great. I hadn't considered that they could be.
