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 to be a real pain for someone who isn't an electrical engineer! Seems the PCB layout needs to be extremely specific, but on top of that the actual physical design is a real pain to work with to ensure no bridging (3x3mm QFN-10, leads completely under the package). Any comparable buck/boosts that are a bit more forgiving in layout and soldering? Say 300mA+ output, input voltage about 3.0V - 4.3V (5V an advantage). An enable pin would also be preferable to shut it down (5V in particular). For running a PIC project off a single li-ion cell. Any thoughts greatly appreciated Lee --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
