I posted the last two patents on another thread regarding this: http://www.freepatentsonline.com/20150056476.pdf http://www.freepatentsonline.com/20150048785.pdf But I didn't read them in detail but the voltages setting is not set on the patent, I think they refer to it as a target voltage. |

Instead of having it supply 1.5V 100% of the time, just let the DC-DC converter bypassed until the battery drops below, say 1.1V, then start the boost and keep the voltage on 1.1V until it drops dead. --- End quote --- If your device has a cut-off voltage of 1.3V and you wait for 1.1V to start boosting, then you wasted your time and money since booster will never engage. Where this thing would be most useful is to make devices with high cut-off work with single-cell NiMH when they normally wouldn't, or at least not for long, because their cut-off voltage is close to full-charge voltage on NiMH, particularly older gadgets which may have been designed to operate off direct battery voltage. |

Do we have any idea what the quiescent power consumption of this dc-dc converter is meant to be? It needs to maintain 1.5V not just into a heavy load, but also a very light one. Most battery powered devices spend most of their time switched off, or at least, in a standby mode where their consumption is microamps. Draw more than a few uA when the device is off, and you're doing more harm than good. The marketing, and perhaps the application itself, isn't doing justice to what could be some genuinely worthwhile technology. Perhaps they do indeed have a notably efficient, small dc-dc converter, which is cheap, robust, and has extremely low standby power use? That in itself is a really useful piece of technology, just not for use in this particular product. |
