The Texas Instruments TPS53659RSBR is a versatile dual-channel DC/DC step-down multiphase controller. It supports VR13 server memory power configurations, offering either a 4+1 or 3+2 phase setup. This controller utilizes D-CAP+ technology for efficient voltage regulation and includes Non-Volatile Memory (NVM) for reduced external component count.
Key electrical specifications include a maximum input voltage of 17V and a minimum input voltage of 4.5V. The output voltage can be regulated from 0.25V up to 2.8125V, with specific ranges of 0.25V to 1.52V or 0.5V to 2.8125V for dual channels. It supports a maximum output current of 160A and operates with a typical quiescent current of 0.013A. The controller features adjustable current limit, dynamic voltage scaling, PMBus interface, and phase interleaving.
Packaged in a 40-WQFN (5x5) surface-mount form factor, the TPS53659RSBR is designed for efficient high-frequency switching. It operates within a temperature range of -40°C to 125°C. Additional features include programmable loop compensations, dynamic phase shedding for efficiency optimization, and compatibility with TI NextFET™ power stages.
