strichSwitcher is a small integrated switching regulator, designed to take 2.8-7V (i.e. battery inputs from standard AA/C/D cells or LiIon/LiPoly cells) and output 5 or 3.3V.
Project Status
Schematic/board done, rev. 1 PCBs received from BatchPCB and parts received from Digikey. Initial order from Digikey shipped resistors instead of caps (330ohm instead of 330pF!), I didn't notice stuffing the board, and something let the magic smoke out (I think the main controller chip). Replacement chip and caps received from Digikey.
Design Overview/Ideas
- Based around the LTC3534 switching controller
- Buck/boost topology to support battery inputs
