Transphorm and TDK-Lambda Announce Expansion of AC-DC GaN Power Module Family
12V and 48V 500 W PSUs Mark Second and Third Products in TDK’s High Efficiency PFH Series
GaN Devices Deliver 38% Power Density Increase Over Silicon-Based Solutions
GOLETA, CALIF.--(Business Wire / Korea Newswire) March 16, 2022 -- Transphorm, Inc. (Nasdaq: TGAN)—a pioneer in and global supplier of high reliability, high performance gallium nitride (GaN) power conversion products—today confirmed that leading power supply manufacturer TDK-Lambda, a group company of TDK, has expanded its GaN-based PFH500F product line. The PFH500F-12 and PFH500F-48 are the second and third modules in TDK’s series of 500-watt AC-DC power supplies. Respectively, they offer 12V and 48V power outputs. As with their predecessor, the GaN-based 28V PFH500F-28, these latest supplies deliver various GaN benefits to end applications including a six percent efficiency increase in a 13 percent smaller device package. Combined, these advantages yield a 38 percent power density improvement when compared to the PFE500SA-12 and PFE500SA-48, TDK-Lambda’s incumbent silicon-based 12V and 48V modules.
The PFH500F series uses 72 mΩ, 8x8 PQFN GaN FETs (TP65H070LDG) from Transphorm. These power transistors’ high power density enabled TDK to cool the GaN power supplies via thin baseplates. In turn, TDK was able to produce a leaner, tightly contained power module capable of supporting a wide variety of broad industrial applications operating in harsh environments. Such applications include commercial off-the-shelf (COTS) power supplies, custom fanless power supplies, 5G communication, laser, digital signage/displays, signaling, and more.
The 12V and 48V PFH500F modules were designed by the TDK-Lambda Americas Dallas, TX team and deploy a bridgeless totem pole PFC configuration. While the flagship 28V GaN power supply took about three plus years to design, TDK’s engineering team was able to adapt its learning to produce these latest models in a year.
“TDK’s decision to launch the PFH500F product line as a GaN line was the result of carefully considering what our customers want and need,” said Jin He, Vice President of Engineering at TDK-Lambda Americas. “And, what our customers require are reliable power systems for use in rugged applications that can’t afford to fail. By using Transphorm’s GaN, we are able to confidently deliver that in increasingly smaller, higher performing PSUs that can also inspire end system innovation.”
TDK-Lambda’s PFH500F-12 and PFH500F-48 power modules deliver the following advantages when compared to the silicon-based PFE500SA-12 and PFE500SA-48:
· Power efficiency: 92% equaling a 6% percent increase
· Power density: > 100W/in^3 equaling a 38% increase
· PMBus™ monitoring and programming (read/write)
· Board Size reduction: From 116.8 x 61 (mm) to 101.6 x 61 (mm) equaling a 13% reduction
· Reduced size of external capacitive components
The PFH500F Series of modules will be on display later this month in Transphorm’s Booth 825 at APEC 2022 in Houston, Texas.
