Here’s how to evaluate energy efficiency associated with components that make up widely used power conversion circuitry. FRANK DE STASI, MATHEW JACOB, TEXAS INSTRUMENTS INC. IN SOME WAYS, selecting a module, converter or controller for power conversion resembles deciding whether to take a flight, board a train, or drive from point A to B. Once […]
Automotive-grade 100-V, 4-A half-bridge N-channel MOSFET drivers target hybrid powertrains
Renesas Electronics Corporation announced a new family of automotive-grade 100V, 4A half-bridge N-channel MOSFET drivers. The ISL784x4 family features three devices: the ISL78424 and ISL78444 with single tri-level PWM input for controlling both gate drivers, and the ISL78434, which has dual independent inputs that separately control the high-side and low-side drivers. The ISL784x4 half-bridge N-MOSFET […]
High-efficiency flyback switcher ICs incorporate 900-V MOSFETs
Power Integrations announced the release of LinkSwitch-XT2 offline switcher ICs incorporating 900 V power MOSFETs. Targeting high-efficiency isolated and non-isolated flyback power supplies up to 8 W, the up-rated ICs are suitable for three-phase industrial power supplies to 480 VAC and high-quality consumer products destined for regions with unstable mains grids, tropical regions with frequent […]
MOSFET delivers low total gate charge to industrial and lighting applications
MagnaChip Semiconductor Corporation announced the introduction of a new High-Voltage Super Junction MOSFET with a 900V breakdown voltage and low total gate charge (Qg) (90R1K4P). The device with two package types, I-PAK and D-PAK, will sample to customers in November 2018 and will be manufactured in high volume in early first quarter of next year. […]

1700V SiC MOSFET optimized for high-frequency, high-efficiency applications
Littelfuse has announced their first 1700V SiC MOSFET, the LSIC1MO170E1000, expanding its portfolio of SiC MOSFET devices. An important addition to the Littelfuse SiC MOSFET product offering, the LSIC1MO170E1000 is a powerful addition to the company’s 1200V SiC MOSFETS and Schottky diodes already released. End-users will benefit from more compact, energy-efficient systems and also from a […]
eGaN power transistor hits 97% efficiency at 500 kHz
The EPC2051 is a 100-V GaN transistor with a maximum RDS(on) of 25 mΩ and a 37-A pulsed output current for high efficiency power conversion in a tiny 1.1-mm2 footprint. Applications demanding higher efficiency and power density no longer have to choose between size and performance. The EPC2051 measures just 1.30×0.85 mm (1.1 mm2). Despite the small footprint, […]
SiC MOSFET structure reduces resistance and boosts energy efficiency in power devices
Hitachi Ltd. says it has developed a new kind of silicon-carbide-based MOSFET that has dramatically lower on resistance than comparable devices. The new MOSFET uses what Hitachi calls a TED-MOS structure, for Trench-etched DMOS-FET. Compared to conventional DMOS-FET (Double-diffused MOSFET) devices, the new structure is said to reduce electric field strength, an index of durability […]
