Auto-Rated High-Withstand Voltage Detector Cuts Detect Time by Up to 92%

4 days ago | electronicdesign.com | Lee Goldberg

Target applications include DC-DC converters, onboard chargers (OBCs), ADAS domain controllers, and battery-management systems (BMS). The detectors are housed in an ultra-compact HSNT-6 (1.96 × 2.46 × t0.5 mm) package, achieving an approximate 20% reduction in footprint than conventional products.
High-Density Power Module Fits AI-at-the-Edge Applications

4 days ago | electronicdesign.com | Lee Goldberg

The MCPF1412 from Microchip Technology is a high-efficiency, fully integrated point-of-load 12-A power module integrating a 16-V V IN buck converter and support for I2C and PMBus interfaces. Its compact form factor of 5.8 × 4.9 × 1.6 mm and innovative land-grid-array (LDA) package reduce required board space by over 40% compared to traditional discrete solutions.
Multiphase Controller Powers AMD SVI3 CPUs in Graphics, Desktop Systems

Vishay Intertechnology expanded its LTO series of thick-film power resistors with a new AEC-Q200-qualified device that delivers higher pulse absorption up to 75 J/0.1 s (30% higher than previous LTO devices) and power dissipation of up to 150 W.
Non-Isolated DCMs Shrink Converter Size Sixfold

1 month ago | electronicdesign.com | Lee Goldberg

By Lee Goldberg Vicor's new non-isolated, regulated DC-DC converter modules (DCMs) are low-profile-package (SM ChiP) devices that offer a 6X reduction in size over a conventional converter. They can be utilized to establish a 12-V bus or used with legacy, downstream point-of-load (PoL) converters. The DCMs are well-suited for bridging 48-V and legacy 12-V power buses in industrial, aerospace and defense, and high-performance-computing (HPC) applications.
