New ICs from STMicroelectronics Deliver Highest Power-Conversion Efficiency for Next-Gen 48V Datacenter Architecture Presented by Google
(Thomson Reuters ONE) -
* Innovative, scalable, isolated power conversion architecture of new 48V
power architecture reduces power loss, space needs, and cooling costs
* Family of three ICs is in production and shipping now, in volume
Geneva, March 10, 2016 - STMicroelectronics (NYSE: STM), a global semiconductor
leader serving customers across the spectrum of electronics applications, today
announced a new family of power-conversion ICs dedicated to 48V power
architectures. These three new products are shipping in volume.
To meet ever-growing performance demands, servers and processors have ratcheted
up their compute power-and power consumption-with multicore chips. This next-
generation power architecture aims to significantly cut wasted power inside
datacenter servers and it also meets the requirements of the new 48V
architecture announced by Google.
ST has implemented direct digital power conversion from 48V by developing a
family of ICs to support the complete range of datacenter power-conversion
applications. The direct digital power conversion eliminates intermediate
conversion stages to minimize power loss in datacenters from power distribution
and reduce space, cooling requirements, and cost. The ICs are fully compliant
with Intel's VR12.5 (Haswell and Broadwell), VR13 (Skylake) and DDR3/4 voltage-
regulation specifications, and all FPGAs and ASICs for datacenter applications.
The three new chips, together with ST's low-voltage StripFET(TM) power-MOSFET
family, assure robust and highly-efficient system operation at input voltages
from 36 to 72V, with output voltages between 0.5 and 12V. These specifications
confirm best-in-class power efficiency of >97% at 12V/500W and high system
bandwidth using minimal PCB space.
"This 48V architecture is ideal for ultra-high-efficiency datacenters in
significantly reducing the total cost of ownership," said Matteo LoPresti, Group
VP and General Manager Analog, STMicroelectronics. "ST is already in volume
production and supporting this next-generation application with our unique
isolated resonant-power converters, demonstrating that this solution offers
industry-leading power efficiency, along with outstanding scalability, and
flexibility."
The three ICs are available now and ST offers a demo board to showcase the
advantages of the 48V architecture and its three-chip solution. For more

Technical Notes for Editors:
ST's Isolated Resonant Direct Conversion technology ensures great flexibility in
all the possible applications. In particular:
* STRG02 is a secondary-side controller that features predictive Zero-Voltage
Switching and Zero-Current Switching control and while permitting power to
be sunk during falling adaptive voltage scaling.
* STRG04 is a 60V full bridge that provides driver capability to a wide range
of external MOS- (Metal Oxide Semiconductor) or Gallium-Nitride-based
switches at high frequency. The chip supports a wide input-voltage range to
substantially simplify the power-delivery chain, including allowing direct
connection of the battery backup, which enables higher system availability.
* STRG06 is a scalable digital power controller that for the 48V datacenter
server architecture to manage up to six converters in parallel, supporting
output power from 50W to more than 300W. The STRG06 also implements Energy
Proportional control, adaptive interleaving, current sharing and a complete
set of the extensive PMBUS(TM) commands for fault management, primary- and
secondary-side telemetry data, and safety system for traceability and
analysis, to operate as a datacenter black-box recorder.
