Beschreibung

The TPS568215 is TI's smallest monolithic 8-Asynchronous buck converter with an adaptive on-timeD-CAP3™ control mode. The device integrates lowRDS(on) power MOSFETs that enable high efficiencyand offers ease-of-use with minimum externalcomponent count for space-conscious powersystems. Key features include a very accuratereference voltage, fast load transient response, autoskipmode operation for light load efficiency,adjustable current limit and no requirement forexternal compensation. A forced continuousconduction mode helps meet tight voltage regulationaccuracy requirements for performance DSPs andFPGAs. The TPS568215 is available in a thermallyenhanced 18-pin HotRod™ QFN package and isdesigned to operate from –40°C to 150°C junctiontemperature. TPS568215 is pin to pin compatible withTPS56C215 which gives the user flexibility to picksolutions from 6A to 12A in the same footprint.
