1.3 Description
The TPS650860 device is a single-chip power-management IC designed for multicore processors, FPGAs,
and other System-on-Chips (SoCs). The TPS650860 offers an input range of 5.6 V to 21 V, enabling a
wide range of applications. The device is well suited for NVDC and non-NVDC power architecture using
2S, 3S, or 4S Li-Ion battery packs. See the Application Section for 5-V input supplies. The D-CAP2™ and
DCS-Control high-frequency voltage regulators use small inductors and capacitors to achieve a small
solution size. The D-CAP2 and DCS-Control topologies have excellent transient response performance,
which is great for processor core and system memory rails that have fast load switching. An I²C interface
allows simple control either by an embedded controller (EC) or by an SoC. The PMIC comes in an
8-mm × 8-mm, single-row VQFN package with thermal pad for good thermal dissipation and ease of board
routing.
