I don't think such a thing exists. =A0If it does, you would need to google = around vigorously and bypass the major suppliers. The cheapest thing with pins I could easily find was the LTC3532, but that = is nearly $5. DFN/QFN is not really all that difficult with solder paste and a stencil. It can also be done without a stencil for a 1-off prototype, as can be seen= in this video. https://www.youtube.com/watch?v=3DsFcfGvQmqAQ https://www.= youtube.com/watch?v=sFcfGvQmqAQ ---------------------------------------- > Date: Wed, 15 Apr 2015 11:26:41 +1000 > Subject: [EE] Suggestions for cheap, simple buck boosts? > From: lee@baudalign.com > To: piclist@mit.edu > > G'day all > Any suggestions on some cheap (~$2 max), SIMPLE (SOT, SOIC, MSOP etc) > buck/boosts for 3.3V and 5V? > I've got the TI TPS63001 (3.3V) and TPS63002 (5V), but they are proving t= o > be a real pain for someone who isn't an electrical engineer!
