DC-DC converter starts up and operates from a single photocell

The bq25504 from Texas Instruments is a good candidate to become a milestone on the road to micro-power management and energy harvesting. A prominent feature of this IC is its ability to start up at a supply voltage as low as 330 mV typically, and 450 mV guaranteed. With an SMD inductor and a few capacitors and resistors, it forms a dc-dc converter with a high power efficiency that is unprecedented, especia ...

3.3V to 30V DC/DC converter using SN6505A

Recently I'v got my samples of SN6505A, it's a really nice IC, so I decided to make a simple DC/DC converter to get familiar with it. What I like in this chip is that it can operate on input voltage as low as 2,5V - that makes it great for battery devices. It's also nice, that it's a very minimalist design - on primary side all what is needed is decoupling capacitor. One disadvantage is that it doesn't have ...
