The PSMA (Power Sources Manufacturers Association) Packaging Committee announced today that it has published a report titled “Current Developments in 3D Packaging With Focus on Embedded Substrate Technologies.” The first comprehensive study on using embedded substrate technology for building power sources, the report contains extensive research and product illustrations geared to an audience of technology executives and design engineers. Its purpose is to offer an in-depth industry perspective on how currently available materials and processes can be best used for the creation of advanced high-efficiency, high-power-density power products. Every chapter covers manufacturing issues and includes references to contract manufacturing companies already producing power products utilizing embedded substrate technology. Embedded substrate packaging leverages the large investment made by the digital industry in advanced packaging technologies and is being used to resolve the power source construction challenge. As the report demonstrates, 3D power packaging using embedded substrate technology is a disruptive technology, in that it enables large increases in power density and efficiency.

CUI announced the release of its highest current digital POL family to date. Designed specifically to address the rapidly-rising power requirements of today’s most advanced integrated circuits, the NDM3Z-90 is a non-isolated module outputting 90 A in ultra low-profile vertical and horizontal packages. The series delivers benchmark power levels while incorporating a range of advanced digital features, including programmable output range, active current sharing, voltage sequencing, voltage tracking, synchronization and phase spreading, programmable soft start and stop, as well as a host of monitoring capabilities. The NDM3Z-90 series is available with an input range of 7.5 to 14 Vdc and a programmable output range of 0.6 to 1.8 Vdc. All digital features will be dynamically programmable via PMBus commands or through CUI’s Novum ACE GUI. The 90 A family is available in two compact through-hole configurations, a vertical version measuring 50.80 X 9.47 X 19.10 mm and a horizontal version measuring 50.8 x 19.1 x 9.7 mm. For added flexibility during the development process, the modules are footprint nested to accommodate dual layout needs in the event that design requirements change.
Efficient Power Conversion Corporation (EPC ) introduced the EPC9115, a demonstration design for a 12 V, 42 A output with an input range of 48 V to 60 V. The demonstration board features enhancement-mode (eGaN) power transistors – the EPC2020 (60 V) and EPC2021 (80 V) – along with the LM5113 half-bridge driver and UCC27611 low side driver from Texas Instruments. The power stage is a conventional hard-switched 300 kHz isolated buck converter. The complete converter fits within a standard eighth-brick envelope, but the EPC9115 demonstration board is deliberately oversized to allow connections for bench evaluation. The design provides various probe points to facilitate simple waveform measurement and efficiency calculation.
The EPC9115 uses a full-bridge primary power stage, a 4:1 transformer, and a center-tapped output stage with active reset snubbers. Control is provided by a Microchip dsPIC controller and basic voltage-mode control is implemented. Operating at 300 kHz, the EPC9115 switching frequency is 50% to 100% higher than similar commercial units.
Power Integration offers new family of Qspeed 150 V diodes. The LQA150 series are the industry’s fastest silicon diodes devices and also feature excellent softness for low EMI. Based on the company’s merged-PIN technology, the diodes have the lowest junction capacitance (CJ ) and lowest reverse recovery charge (QRR ) in the market – respectively 60% and 40% lower than trench Schottky devices. The device facilitates high-frequency operation, so that small and inexpensive magnetic components may be used while maintaining maximum efficiency. The devices’ EMI performance means that the need for snubber capacitors is also reduced or even eliminated, further improving efficiency and reducing cost.
The Coilcraft flyback transformers are designed to meet IEEE 802.3at-2009 standards for PoE Plus applications up to 30 Watts. Common PoE applications include VoIP telephones, IP cameras with pan tilt and zoom (PTZ), wireless access points, network routers and remote Ethernet switches. POE300F Series transformers operate at 250 kHz with 36 to 72 Volts input. They provide 1500 Vrms primary-to-secondary isolation; 500 Vrms primary-to-auxiliary. They feature RoHS compliant tin-silver over tin over nickel over phos bronze terminations and offer a maximum reflow temperature of 260°C. As with all Coilcraft parts, free evaluation samples and complete technical specifications for POE300F Series flyback transformers are available online at www.coilcraft.com/poe300.cfm
Coilcraft also introduced a new CST2010 series of current sense transformers. The devices detect switching current up to 40 A over a frequency range from 50 to 500 kHz while also isolating circuits electrically, resulting in up to 10X lower power dissipation than current sense resistors. They suit switched-mode power supply applications, including feedback control, overload detection, and load drop/shut down detection. The transformers offer 500 Vrms isolation between windings and very low primary DC resistance (0.00036 Ohms). It features RoHS compliant tin-silver, over tin, over nickel, over phosphor bronze terminations and has an ambient temperature rating of -40° to +125°C.
Infineon Technologies introduced the OptiMOS 5 25- and 30-V product family is available in standard discrete packages, a new class of power stages named Power Block, and in an integrated power stage, DrMOS 5×5. Together with Infineon’s driver and digital controller products the company delivers full system solutions for applications such as server, client, datacom or telecom. The family offers benchmark solutions with efficiency improvements of around 1 percent across the whole load range compared to its previous generation. This improved performance is based for example on the reduction of switching losses (Qswitch ) by 50% compared to the previous OptiMOS technology. Implementing the new OptiMOS 25V would lead to energy savings of 26.3 kWh/year for a single 130-W server CPU working 365 days/year.
