[edit] Charge pump illustration
a good way to explain the basic idea (which we should do) is to show two caps on top of each other, with two SPDT switches. Show the 5 or whatever V battery being connected across one capacitor, then disconnected, then connected across the other, and then show that the total voltage across both caps is 10 V. - Omegatron 23:04, Mar 19, 2005 (UTC)
- That sounds like a charge pump and should probably go there. Do note that a standard voltage-doubling charge pump doesn't actually do this -- rather, it charges the flying capacitor to V+, then connects cap- to V+ and cap+ to Vout, thus using only one flying capacitor.

[edit] Merge
Give one good reason why we should. --Heron 13:41, 26 May 2007 (UTC)
[edit] DC-DCs are switchers
I have never heard of a linear regulator referred to as a DC to DC converter. This article seems to be interpreting its title literally, and not as a technical term with a specific meaning. Is there any practising engineer out there who thinks that linear regulators should be included in this article? --Heron 09:53, 27 May 2007 (UTC)
- I would say that linear regulators deserve a brief mention and an explanation of why they aren't included in any detail (and a link to the right article, obviously). Evand 01:55, 28 May 2007 (UTC)
- I agree that linear regulators aren't DC/DC converters. An ideal converter has 100% efficency, a linear regulator would never achieve this level, neither theorically. A brief mention could be interesting, butthen a new article is needed, and more information should be added to this one--Iruando (talk) 23:43, 20 February 2008 (UTC)
[edit] batteries?
It's said in the article that DC converters are to be connected to a battery. It's true in portable applications, but all of us use DC converters plugged to a rectifier connected to the AC network in our computers. The DC converters are connected to a power source of positive voltage, and supply DC current with no theorical power losses.--Iruando (talk) 23:43, 20 February 2008 (UTC)
[edit] Step-up and step-down
The article mentions the following under the header "Non-isolated topologies (using inductors)"
* Buck (step-down) - The output voltage is higher than the input voltage, and of the same polarity * Boost (step-up) - The output voltage is lower than the input voltage, and of the same polarity
Shouldn't this just be the other way around? Step-down results in a lower voltage and step-up in a higher voltage? —The preceding unsigned comment was added by P.edelman (talk • contribs) 07:39, August 21, 2007 (UTC).
[edit] True Buck-Boost
The link True Buck-Boost links to inverting buck-boost. Should we add the true Buck-Boost as described in the datasheet for LM2578 [1] (fig 22)? It seems to be a simple combination of the buck circuit and boost circuit, and it does the job of a SEPIC, with one inductor and capacitor! I've tried the concept using a Onsemi IC (NCP3063) and it works too! With a 6 V nominal input, I got 1.25 V - 10 V output, current in the tens of mA range. Gohsc (talk) 06:46, 23 January 2008 (UTC)
