48V Digital Power Conversion Turnkey Solution

Efficiency, Density, Flexibly and Scalability to power next generation 48V data centers

Responding to the next generation data center power requirement ST introduces a new generation of high performance ICs for 48V bus power conversion.
The ICs family provides all the ingredient to the data center designer to customize their system power distribution according to their needs achieving the highest level of overall power conversion efficiency.
The flexibility in supporting multiple conversion topologies with scalable power train allows optimized design in for both direct conversion and intermediate bus distributions.
The IC family fully compliant to the newest features in terms of communication protocol and specific power management requirement: SVI protocol for VR13 (Skylake), VR13.HC (Icelake) and DDR4 platforms; AVSBus based microarchitectures ; FPGAs and ASICs featuring PMBUS.
The new ICs IP are a key enabler for of high power density implementations: Power Stamp Alliance (PSA) developed product based on ST technology ensuring the final customers of multiple sourcing of on-board isolated and non isolated DC-DC power converters.

The IC family features

  • STPDDC60: Universal digital multicell controller with PMBus™
  • PSA60: Digital multicell controller with PMBus™ optimized for PSA Designs
  • STPRDC02: High performance high voltage full-bridge driver
  • STPRDC01: Synchronous rectifier smart driver
