The TPS650861 multi-rail PMIC from Texas Instruments (TI) is available from Mouser Electronics. Integrating three controllers to deliver power up to 30A using large external FETs, the configurable power management integrated circuit (PMIC) offers flexible power solutions for multiprocessor systems-on-chip (MPSoCs) and field-programmable gate arrays (FPGAs).
The PMIC, features three variable-output voltage synchronous step-down converters with DCS-control topology, delivering up to 3A of output current.
Additionally, three variable-output voltage synchronous step-down controllers with D-CAP2 topology offer scalable output current via external FETs.
The device’s small passives enable a small solution size of just 8mm × 8mm, while the DCS-control and D-CAP2 topologies provide excellent transient response performance for processor core and system memory rails that have fast load switching.
The TPS650861 PMIC features an I²C interface that supports a 100kHz standard mode, 400KHz fast mode, and 1MHz fast mode plus. The device features three adjustable-output low-dropout (LDO) regulators plus an LDO regulator for DDR termination.
Two banks of one-time programmable (OTP) memory enable engineers to program default voltages and sequences. The PMIC features three load switches with slew rate control, providing up to 300mA of output current with voltage drop of less than 1.5% of nominal input voltage.
The TPS650861 PMIC’s combination of switches, converters, and LDO regulators makes the devices suitable for programmable logic controllers, machine vision, video surveillance, motion control, and test and measurement applications.
