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-Reflex™ DSPs. - Enabling Multiple TPS4019x DevicesPDF, 72 Kb, Archivo publicado: marzo 29, 2012
