$5.83 at Digikey vs. $3.24 (min qty 2) directly from Linear. Anyone ever order directly from Linear? Lead time? Issues? -----Original Message----- From: Jesse Lackey Sent: Feb 15, 2004 10:58 PM To: PICLIST@MITVMA.MIT.EDU Subject: Re: [EE]: Boost & Buck regulator in one? I've done something very similar with good success. Getting a clean 3.3V (actually, two clean 3.3V supplies, one digital and one analog) from a single li-ion cell, that ranges from ~4.05V to 3V. Linear's LTC3440 is designed to do exactly this. I have it set via 1% resistor divider to produce around 3.8V to feed to the two 3.3V LDOs. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
