EPC adds 5mΩ 150V and 7mΩ 260V eGaN FET power transistors

Efficient Power Conversion Corp (EPC) of El Segundo, CA, USA, which makes enhancement-mode gallium nitride on silicon (eGaN) power field-effect transistors (FETs) for power management applications, has launched two eGaN FETs that have a maximum operating temperature of 150°C and maximum pulsed drain currents of 260A for the 150V EPC2033 and 140A for the 200V EPC2034, which have a typical typical on-resistance (RDS(on)) of 5mΩ and 7mΩ, respectively.

Applications include DC-DC converters, synchronous rectification in DC/DC and AC/DC converters, motor drives, LED lighting, and industrial automation.

The products further expand EPC's family of 'Relaxed Pitch' devices featuring a 1mm ball pitch. The wider pitch allows the placement of additional and larger vias under the device to enable high current-carrying capability despite the extremely small 2.6mm x 4.6mm footprint.

To simplify the evaluation process of the eGaN FETs, the EPC9047 development board is available to support easy 'in circuit' performance evaluation of the EPC2033. In a half-bridge topology measuring 2" x 1.5", the EPC9047 contains two EPC2033 eGaN FETs using the Texas Instruments UCC27611 gate driver, as well as supply and bypass capacitors. The board contains all critical components that can be easily connected into any existing converter, plus layout for optimal switching performance. There are also various probe points to facilitate simple waveform measurement and efficiency calculation.

The EPC2033 and EPC2034 are priced at $4.25 and $4.37, respectively (in 1000-unit quantities). The EPC9047 development board is $137.75. All are available now for delivery from Digi-Key.
