    Buck-boost and half-empty batteries?

    Hello, :-) I still got piles of half-empty zinc-carbon batteries. My idea was to connect a few of them together and then use a buck-boost converter to power clocks, thermometers and other "small stuff". I've been reading up on various information regarding this. The essence: There can be...

    Paralleling Buck Modules?

    Hi This TI note says we can parallel the LM2587. https://www.ti.com/lit/an/snva552/snva552.pdf Is it safe and functional to parallel these off-the-shelf buck modules? LM2596: **broken link removed** https://www.monolithicpower.com/pub/media/document/MP1584_r1.0.pdf MP1584: **broken...
  3. Constant current circuit for buck converter

    Hi and thanks for viewing! In the past I've used a few buck converters off ebay. So far they've done me well, but I'd prefer to have the ability to build my own. That way I'm in control of the quality of components used. I was planning on using the LM2678T-AJT as the heart of my buck converter...
  4. Non-Linear Resistance Control

    All, I’m working a project in which I will need to control the output of a DC/DC converter using a microcontroller. I’m planning on using the LM27402 DC/DC Controller IC from TI. My application circuit will be very similar to the circuit taken from page 2 of the evaluation board datasheet and...

    Buck converter not working as it should

    Hello everyone. I am doing a project in which I use a buck converter to convert high vtg to low vtg. Actually the input to the buck converter is from a solar panel which puts out 560 mA constant current and 34 V. And output is a 12V lead acid battery. The N- Channel mosfet is used at high side...
