Eight-port PoE switch provides 60 W per port
The adoption of commercial smart lighting systems has grown significantly as organizations strive to improve energy efficiency and operational costs in buildings. Power over Ethernet (PoE) is rising in popularity for these systems, providing a reliable and easy-to-install solution that manages power and data over a single Ethernet cable. To support larger and more efficient […]
Specialized diodes, Part 2: Varactor, Gunn, and PIN diodes
Part 1 of this FAQ reviewed the standard PN semiconductor diode, and looked at some specialized variations called the tunnel, Zener/avalanche, and Schottky diodes. Part 2 briefly explores the varactor, Gunn, and PIN diodes. Q: What about the varactor diode? A: The varactor diode (Figure 1), also called a voltage variable capacitor (VVC) or varicap […]

Evaluating options for USB Type-C connections
Port controllers, transceivers, and special dc/dc converters now simplify the task of adding USB Type-C functions. DANIEL LEIH, MICROCHIP TECHNOLOGY INC. CONSIDER THE VIRTUES of the USB-C connector. In addition to its 10 Gbit/sec (Gbps) bandwidth and Alt Mode video capabilities, two attributes, in particular, make this form factor incredibly valuable: a reversible plug and […]
Dual-mode power monitoring IC includes power calculations and event monitoring
In systems that use both AC and DC power, the implementation of dual-mode power monitoring traditionally requires multiple ICs to ensure superior performance and accuracy. Growing applications such as solar inverters, smart lighting and cloud servers often use both modes to maintain safe operation, with AC as the main power source and DC as backup […]
Single-chip power monitor targets FPGA, GPU circuits
Managing and reducing power consumption is crucial in low-voltage, high-power applications such as Field-Programmable Gate Arrays (FPGAs), Graphics Processing Units (GPUs) and embedded computing devices. These devices must first accurately measure power before they can manageit, but precision power measurement solutions are often costly and require multiple ICs or power configurations to measure different rails.
