应用须知
- TPS40197 Reference DesignPDF, 614 Kb, 档案已发布: Dec 17, 2008
The TPS40197 reference design is a synchronous buck converter providing VID programmable output voltage from 0.9 V to 1.2 V at up to 7 A from a 12-V or 5-V bus (4.75 V ~ 13.2 V). The design uses the TPS40197 – a synchronous buck controller with 4-bit VID interface for Smart-Reflexв„ў DSPs. - Enabling Multiple TPS4019x DevicesPDF, 72 Kb, 档案已发布: Mar 29, 2012
