Efficient Power Conversion Corporation Key Developments

Efficient Power Conversion Introduces Monolithic Gallium Nitride Power Transistor Half Bridge Enabling over 97% System Efficiency for A 48 V to 12 V Point of Load Converter at 22 A Output

Efficient Power Conversion announced the EPC2104, 100 V enhancement-mode monolithic GaN transistor half bridge. By integrating two eGaN power FETs into a single device, interconnect inductances and the interstitial space needed on the PCB are eliminated, resulting in a 50% reduction in board area occupied by the transistors. This increases both efficiency (especially at higher frequencies) and power density, while reducing assembly costs to the end user’s power conversion system. The EPC2104 comes in a chip-scale package for improved switching speed and thermal performance, and is only 6.05 mm x 2.3 mm for increased power density. The EPC2104 is ideal for high frequency DC-DC conversion and motor drive applications. The EPC9040 is 2” x 2” and contains one EPC2104 integrated half-bridge component using the Texas Instruments LM5113 gate driver, supply and bypass capacitors. The board has been laid out for optimal switching performance and there are various probe points to facilitate simple waveform measurement and efficiency calculation. The EPC2104 monolithic half-bridge price for 1K units is $8.31 each. The EPC9040 development boards are priced at $137.75 each.

Efficient Power Conversion Introduces Wide Pitch eGaN FETs Enabling High Current in Small Footprint

Efficient Power Conversion Corporation announced the introduction of an eGaN FET designed with a wider pitch connection layout. The first in a new family of 'Relaxed Pitch' devices, the EPC2029 80 V, 31 A eGaN FET featucres a 1 mm ball pitch. The wider pitch allows for placement of additional and larger vias under the device to enable high current carrying capability despite the extremely small 2.6 mm x 4.6 mm footprint. Compared to a silicon power MOSFET with similar on-resistance, the EPC2029 is much smaller and has many times superior switching performance. The EPC2029 is ideal for applications such as high frequency DC-DC converters, synchronous rectification in DC/DC and AC/DC converters, motor drives, and class-D audio. To simplify the evaluation process of this latest high performance eGaN FET, the EPC9046 development board is available to support easy “in circuit” performance evaluation of the EPC2029. The board is a half-bridge topology with onboard gate drives, featuring the EPC2029 eGaN power transistor. The board is 2” x 2” and contain two eGaN FETs using the Texas Instruments LM5113 gate driver, supply and bypass capacitors. It contains all critical components and is laid out for optimal switching performance with additional area to add buck output filter components. There are also various probe points to facilitate simple waveform measurement and efficiency calculation. Pricing for the EPC2029 power transistors at 1K units is $6.03 each and pricing for the EPC9046 development board is $137.75. Both products are available for immediate delivery from Digi-Key.

Efficient Power Conversion Introduces Enhancement Mode 450 V Gallium Nitride Power Transistors for High Frequency Applications

EPC announced the EPC2027, a 450 V normally off (enhancement mode) power transistor for use in applications requiring high frequency switching in order to achieve higher efficiency and power density. Applications enhanced by high voltage higher switching speeds include ultra-high frequency DC-DC converters, medical diagnostic equipment, solar power inverters, and LED lighting. The EPC2027 has a voltage rating of 450 V and maximum RDS(on) of 400 m¦ with a 4 A output. It is available in passivated die form with solder bars for efficient heat dissipation and ease of assembly. The EPC2027 measures 1.95 mm x 1.95 mm for increased power density. As off-line adapters and inverters increasingly push toward smaller size, less weight, and higher power density, the demand for corresponding higher voltage and faster switching speeds is increasing. The 450 V EPC2027 allows power designers to increase the switching frequency of their off-line power conversion systems for increased efficiency and smaller footprint. Price and Availability of the EPC2027 eGaN FETs are priced for 1K units at $5.81 each. The EPC9044 development boards are priced at $137.75 each.
