Only 8-80V upt to 400W I love it CC and/or CV mode digitally programmable and probably some day you'll find open source code for it! Just like I recently found for my Imax B6 universal battery charger! http://www.ebay.com/itm/DC-DC-400W-6-40V-to-8v-80v-10A-Boost-Converter-Step= -up-Module-Power-Supply-CC-CV-/111177068259?pt=3DLH_DefaultDomain_0&hash=3D= item19e2ab6ee3 On 1/21/15, Trevor Hancock wrote: > > From TI http://www.ti.com/product/TL783 > > Description > > The TL783 is an adjustable three-terminal high-voltage regulator with an > output range of 1.25 V to 125 V and a DMOS output transistor capable of > sourcing more than 700 mA. > > I know of these but have not used them.
