TPS650861 (ACTIVE) Configurable Multi-Rail PMIC for MPSoCs and FPGAs

 

Description

The TPS650861 device family is a single-chip power-management IC (PMIC) designed to be programmed for optimal output voltages and sequencing. The TPS650861 has three controllers to provide flexible power capable of up to 30A with large external FETs for high power designs but which can scale down in both size and cost for smaller designs. Combined with three 3 A converters, three general purpose LDOs, a termination LDO for DDR, and three load switches, the TPS650861 can provide system power for a wide variety of applications. The D-CAP2™ and DCS-Control high-frequency voltage regulators use small passives to achieve a small solution size. The D-CAP2 and DCS-Control topologies have excellent transient response performance, ideal for processor core and system memory rails that have fast load switching. The device has two banks of one-time programmable (OTP) memory. For large volume opportunities, please contact a local TI sales representative to determine if use of TI’s manufacturing for a custom OTP is available. Third party distributors may also support programming of the TPS650861.
