3 Description
The TPS56C215 is a small-sized, synchronous buck
converter with an adaptive on-time D-CAP3™ control
mode. The device offers ease-of-use and low bill-of
material count for space-conscious power systems.
This device features high-performance low RDSon
integrated MOSFETs, accurate 0.6-V reference, and
an integrated boost switch. Competitive features
include very-low external-component count, fast load
transient response, auto-skip mode operation,
internal soft-start control, and no requirement for
external compensation. A forced continuous
conduction mode helps meet tight voltage regulation
accuracy requirements for performance DSPs and
FPGAs. The TPS56C215 is available in a thermally
enhanced 18-pin HotRod™ QFN package and is
specified from –40°C to 150°C junction temperature.
