At APEC 2024, Power Integrations‘ chairman and CEO, Balu Balakrishnan, “declared war on DC-DC post regulators”, as the company introduced the GaN-based InnoMux-2 switcher IC family. The company said that the new ICs are an example of its value and energy focus because it combines AC-DC and DC-DC stages into a single power converter, resulting in a reduction in power ...

EPC is claiming “the lowest on-resistance GaN FET on the market” for its 1mΩ 100V EPC2361, which comes in a 3 x 5mm QFN package with top and bottom cooling. 1mΩ is at 50A 25°C with 5V on the gate, and rises to ~1.8mΩ at the max operating temperature of 150°C (minimum is -40°C). The preliminary data sheet has no ...

Analog Devices has created a stand-alone 100V half-bridge driver for GaN power hemts “with a propagation delay of 10ns and delay matching of 1.5ns between the top and bottom channels, making it suitable for high-frequency dc-dc converters, motor drivers and class-D audio amplifiers”, according to the company. Called LT8418, this IC looks very much like the output stage used within ...

Advanced Energy Industries is showing its NP08 4kW ac-dc power supply at APEC in Long Beach this week. The first member of its NeoPower (NP) family of configurable multi-output supplies, it has eight output slots for configuration and 18W/inch3 claimed density for ~283 x 203 x 64mm chassis. Input is single-phase 90 – 132Vac and 180 – 264Vac. “NP08 also ...

Microchip is aiming at motor control by combining a triple half-bridge mosfet gate driver, a 100MHz processor and CAN FD transceivers in the same IC. Other members of the family offer LIN transceivers instead of CAN, or a CAN interface without transceivers, or no CAN or LIN, and a base model has a 70MHz processor. Some have SENT interfaces for ...

Resistors, capacitors and inductors from a renowned manufacturer. In the modern world, basic electronic components, such as resistors, capacitors, and inductors are often overshadowed by the universally applied microprocessors. However, it is these seemingly insignificant components that form the foundation without which no advanced electronic system could exist. Thanks to them, the basic tasks and functions of electronic circuits can ...

Rohm has created a proprietary trench MOS structure for 100V Schottky diodes to improve the trade-off between forward voltage and reverse leakage. It has been used to create the YQ series of rectifier diodes, available in surface-mount packages from 0.5 x 1mm to TO-263 with ratings between 1A and 30A. Most of them are available with automotive qualification. Leakage is ...

The MX-Q Series 2 is the updated version of the MX series DC power supply by Aim-TTi. The quad-channel power supply has a larger colour panel, with colour-coded outputs. It also includes a TripLink feature, which allows the user to define assigned outputs for over-voltage protection and over-current protection. Aim-TTi says it has also enhanced power sharing between outputs. The ...

Cosel has announced a series of ac-dc power supplies with enhanced reliability for industrial applications. Called the PDA series, the PSUs are form, fit and function backwards compatible with the company’s 20 year old PBA series, with fewer internal components explaining part of the reliability increase. With more to follow, the initial versions are: PDA15F (15W 31 x 78 x 85mm), ...

EPC has created a GaN transistor dc-dc converter demo board that converts an input between 36 and 60V to a regulated 13V 16A output. Called EPC9195, it is a synchronous buck converter built around a pair of 2.5 x 1.5mm EPC2619 GaN hemts, and an LTC7891 controller IC from Analogue Devices. “48V input is getting popular due to USB PD ...
