Code-free driver simplifies setup of RGB ambient lighting systems
Melexis has released the MLX80124, a configurable LIN LED driver designed for automotive ambient lighting applications. The device supports dynamic RGB lighting systems without requiring embedded code development. The MLX80124 allows engineers to configure lighting behavior using a graphical user interface (GUI) instead of writing code. This approach helps streamline the setup of RGB ambient […]
GaN-on-GaN design supports compact, efficient power conversion
Onsemi conductor has introduced a new generation of vertical gallium nitride (vGaN) devices featuring GaN-on-GaN architecture and designed to enhance power density, efficiency, and reliability in high-performance applications. Unlike lateral GaN structures built on silicon or sapphire substrates, the vertical configuration conducts current through the semiconductor material itself, enabling operation at higher voltages and switching […]
SPICE integration models gate driver effects on switching losses
The Infineon Power Simulation Platform (IPOSIM) from Infineon Technologies AG is widely used to calculate losses and thermal behavior of power modules, discrete devices, and disc devices. The platform now integrates a SPICE-based model generation tool that incorporates external circuitry and gate driver selection into system-level simulations. The tool delivers more accurate results for static, […]
