UTAC, Sarda and AT&S Collaborate in Delivering Small, Fast Voltage Regulators to Improve Data Center Energy Effeciency

Sarda’s Heterogeneous Integrated Power Stage (HIPS) Employs UTAC’s 3D SiP using the Embedded Component Packaging (ECP®) Technology from AT&S for Granular Power Delivery

June 15, 2016 – Raleigh, North Carolina and Singapore – Sarda Technologies (Sarda), a disruptive power management component supplier and UTAC Holdings Ltd (UTAC), one of the leading semiconductor assembly and test services providers in Asia, today announced that Sarda will implement its Heterogeneous Integrated Power Stage (HIPS) in UTAC’s three-dimensional system-in-package (“3D SiP”) based on ECP technology from AT&S to improve data center’s energy efficiency.

Designed to address the rapidly escalating power consumption in data centers, Sarda’s HIPS replaces silicon switches with gallium arsenide (GaAs) in voltage regulators that increase switching frequency by 10 times, improve transient response by 5 times and reduce size by 80%. With these fast, small voltage regulators, it enables granular power delivery to reduce data center power consumption by 30%.

The collaboration was announced at the International Symposium on 3D Power Electronics, Integration and Manufacturing Symposium ( in Raleigh, North Carolina, USA.

“UTAC’s 3D SiP enables Sarda to integrate GaAs switches, silicon driver and passive components in a compact, low-profile package that minimizes parasitics for efficient, high speed operation,” said Bob Conner, CEO and co-founder of Sarda. “UTAC’s collaboration with AT&S also provides a full turnkey supply chain assembly and test flow with much needed alignment of roadmaps as well as design rules for 3D SiP solutions with embedded chip in substrate technology.”

“System manufacturers are moving from use of discrete components to highly integrated power management solutions to improve power density and energy efficiency. UTAC is very excited in working closely with Sarda and AT&S to demonstrate the benefits of using 3D SiP to reduce footprint and improve electrical and thermal performance,” said Lee Smith, UTAC Vice President of Advanced Package Product Line.

“Our collaboration with UTAC maximizes the benefits of utilizing AT&S’ ECP technology for the Sarda HIPS Solution”, stated Michael Lang, CEO of Advanced Packaging at AT&S. “The major ECP advantages compared to standard IC packaging and PCB assembly include a significant form factor reduction, higher reliability, improved thermal management and a fast and easy system integration with high efficiency.”

Reducing Data Center Cost-Per-Workload

Servers, routers and communications systems require new power management technology to keep up with the growth in data consumption and mobile connectivity. But power delivery and heat removal issues constrain system performance. Moreover, each system board uses dozens of voltage regulators which consume precious board space.

Designers can no longer rely solely on Moore’s Law to deliver the needed gains in energy efficiency. Leading edge processors now operate at less than one volt, which prevents designers from reducing operating voltage enough to keep power consumption constant while increasing transistor density. Instead, developers are turning to “More-than-Moore Scaling,” which heterogeneously integrates different materials and components to improve system performance-per-watt.

Small, fast voltage regulators enable granular power which reduces system power consumption through dynamic power management of each load. Miniaturizing the voltage regulators also frees up board space for more processors and memory to increase system performance. Increasing system performance-per-watt decreases the system cost-per-workload.

GaAs & Silicon: A New Proposal for Power

Startup says its modules reduce switching loss by 30%

“Sarda Technologies heterogeneously integrated power stage module combines CMOS power drivers with GaAs output transistors in the same QFN package,” writes Ohr. The idea seems quite intuitive, he suggests, adding that it is a wonder it hasn’t been done before. Ohr explains that the crux of Sarda’s technology is “us[ing] gallium arsenide (GaAs) as the power driver for modules in compute servers and communications switching stations. Traditionally used for basestation transmitters, GaAs transistors automatically improve switching power supply frequencies: This enables higher densities for server power transmission applications, reduces heat dissipation, and helps shrink the size of power chain bricks and modules.”

Ohr is a former director for Semiconductor Research at Gartner.

Sarda is a Durham-based, ventured backed company led by Bob Conner. Connor who has 15 years of experience with large corporations and 18 years with startups is joined by team members that include power-management veterans from companies such as Intersil and Harris Semiconductor.
