CHIIPS is brought to you by our editor Caroline Hayes, gathering interesting insights from a wide range of industry figures. Alex Lidow In this episode, Alex discusses his roots in the power semiconductor industry and the challenges faced. ...
EPC has revealed a 6kW 800-to-12.5V dc-dc converter with a novel (input-series output-parallel) topology, as part of Nvidia’s 800Vdc data centre power distribution programme. The GaN hemt based proof-of-concept is 8mm tall and occupies <5,000mm2. “GaN is an essential technology for the 800Vdc ecosystem,” claimed EPC CEO Alex Lidow. While Power Integrations proposes a single half-bridge pair of 1,250V GaN ...
EPC has taken its GaN driver for motorised humanoid robot joints a stage further, squeezing a control MCU and magnetic angular sensing alongside the power stage, all on a 32mm diameter PCB. Once again, the company is using three of its 100V 15Arms EPC23104 monolithic half-bridge ICs, which include power transistors, drivers and level-shifting. Power dissipation is minimised by the ...
With USB Power Delivery in mind, EPC has designed a 180W GaN dc-dc converter evaluation board. Its two-phase power section occupies only 24 x 24mm, using both sides of the board and ignoring input and output bulk capacitors. Called EPC91109 and intended to implement USB-PD 3.1, it delivers 12, 16 or 20V from an input range of 20 to 36V. ...
EPC aims to displace silicon mosfets from secondary-side synchronous rectifiers with its latest 40V GaN power transistor, designed specifically for 48V to 12V LLC dc-dc converters. “With the EPC2366, and upcoming lower voltage parts, we are expanding the GaN beach-head across low-voltage applications that have long been dominated by silicon,” said EPC CEO Alex Lidow. Packaged in 3.3 x 2.6mm ...
EPC has introduced an evaluation board implementing a 40Arms (60A peak) three-phase inverter that will run from 30V to 130V. Called EPC91200, it is “suitable for 80 and 110V battery systems commonly used in industrial automation, agricultural machinery and material handling equipment like forklifts,” according to the company. The inverter is designed around EPC’s 150V 3mΩ EPC2305 GaN HEMT, a ...
EPC is aiming at USB-C PD applications 50V 8.5mΩ GaN transistor with a 1.8mm2 footprint. EPC2057 measures 1.5 x 1.2mm and can handle 9.6A continuously (25°C) and 66A single 300µs pulses (25°C). With such a tiny package, thermals are important. According to the data sheet, junction-to-case thermal resistance is 2.3°C/W, then it is 7°C/W junction-to-board, 72.5°C/W junction to ambient on ...
EPC is aiming at satellites with an application note on four-phase dc-dc point-of load converters using multiple 26 x 19mm modules. The note, AN005, picks a radiation-specified current-mode PWM controller from Texas Instruments (TPS7H5001-SP) as a source of PWM waveforms. Each TPS7H5001-SP can produce two pairs of upper and lower PWMs for a total of two phases, and TPS7H5001-SP has ...
EPC has used GaN transistors to create a high-power Class-D two-channel audio power amplifier design. Instantiated in evaluation kit EPC9192, it is capable of pushing 700W/channel into 4Ω (or 2Ω) or 350W/channel into 8Ω. Bridging the two channels results in 1.4kW drive into 4 to 8Ω. Key components, per channel, are a pair of 200V EPC2307 GaN transistors on a ...
