Modern “switching” DC-DC converters are an essential part of most power supplies.
Overview
DC-DC converters have already been discussed. If you are interested in what a DC-DC converter actually is, and how it works, please review it here.
This section is looking at generic DC-DC converters that are available separately and can be used in DIY projects to lower, raise, or stabilize voltages and limit currents.
Special Use-Cases
Be aware that there are at least two specialty use-cases for DC-DC converters that are discussed separately elsewhere:
- Battery charging:: uses DC-DC converters with separated buck (charge) and boost (discharge) functionality for powerbank scenarios, and to supply battery power to portable electronics.
- Harvesting solar energy: uses DC-DC converters with adjustable duty cycle to support efficient MPPT solar charging
The IP5306 for example is an excellent and highly integrated DC-DC converter chip that comes with separate boost and buck technology to address both charging and discharging scenarios in powerbanks and battery-operated devices. It does so with minimum size at high performance (10W) by using latest and highly efficient regulator technology.

Comments
Please do leave comments below. I am using utteran.ce, an open-source and ad-free light-weight commenting system.
Here is how your comments are stored
Whenever you leave a comment, a new github issue is created on your behalf.
-
All comments become trackable issues in the Github Issues section, and I (and you) can follow up on them.
-
There is no third-party provider, no disrupting ads, and everything remains transparent inside github.
Github Users Yes, Spammers No
To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant utteranc.es the permission to submit issues on your behalf.
If you don’t have a github account yet, go get yourself one - it’s free and simple.
If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.
Discussions
For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
