Micro Power Supply

We have designed a number of "micro" power supplies that you can run from 2.5 - 5V and generate 3.3 to 5V out via buck/boost converters and 80-90% efficiency. We will start with a 3.3/5V model coming out soon. If you do embedded work with li-ion batteries then generating 3.3V and 5V is always a problem since li-ion starts at 4.2V and drops to 2.5-3.0V as it discharges. There is no way to get 5V without a boost converter, but 3.3V can be obtained with a low drop out linear voltage regulator, but then you burn energy, and once the li-ion drops below 3.3V, you can't maintain 3.3V anymore, and most li-ion are still just fine down to 2.7V, but at least 3.0V, so you waste all that energy in the battery. But, with our new micro power supplies, you can put them in your projects and get the most out of your batteries without knowing how to build a SMPS power supply.
