I received some early samples of the MCP1640, price looked great, package, etc. So I put one in a design...works great, just based on the app notes in the data sheet. However, as some have mentioned....can't yet buy the parts. So I did another similar design for the same client...but I used a TI TPS61220 for the boost. Costs more, but I can actually buy the part. I haven't spun the other board yet..still waiting on the clients evaluation to determine when it might go into production and if they aren't ready for it till July then I will keep the part on there. --- On Sat, 5/8/10, Alan B Pearce wrote: > From: Alan B Pearce > Subject: Re: [EE] Microchip boost converters > To: "Microcontroller discussion list - Public." > Date: Saturday, May 8, 2010, 9:53 AM > > [changed subject] > > > >> Microchip have just published a data sheet for a > boost converter > >> working from a single cell for processors.
