Switching frequency400-1200 kHz
Output 15.5 V
IC revision00

Description

The TPS56C215 is TI's smallest monolithic 12-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. Competitive features include a veryaccurate reference voltage, fast load transientresponse, auto-skip mode operation for light loadefficiency, adjustable current limit and no requirementfor external compensation. A forced continuousconduction mode helps meet tight voltage regulationaccuracy requirements for performance DSPs andFPGAs. The TPS56C215 is available in a thermallyenhanced 18-pin HotRod™ QFN package and isdesigned to operate from –40°C to 150°C junctiontemperature.
