Reference design lets secondary MCU control primary power
In modern offline AC-DC power solutions, programmability and adaptive control offer the flexibility and intelligence needed by smart home devices to better interface with their power systems. In these systems, a secondary side microcontroller (MCU) is typically not capable of starting a system without the use of a separate bias power supply. A new reference […]
Rad-hard motor controller IC incorporates position sensing for satellites
The need to reduce size, weight, and power on satellites and other space systems continue to challenge the aerospace market. Combining more than 20 commonly used functions into a single chip, Microchip Technology Inc. announced the LX7720 radiation-hardened mixed-signal motor controller, the latest addition to its Space System Manager (SSM) product family. As the industry’s first highly […]
eGaN demo board covers 48-V dc-dc conversion
EPC announces the availability of the EPC9148 and EPC9153 demonstration boards for 48 V DC-DC conversion. The EPC9153 is a 250 W, extremely thin, power module using a simple, low-cost synchronous buck configuration delivering a 98.2% peak efficiency with a maximum component height of 6.5 mm. The EPC9148 utilizes a multilevel topology enabling a maximum […]
Voltage-clamping diodes handle 3-kW transients
To ensure critical operations, aviation and space systems rely on digital and logic functionality and circuitry in engine control units, environmental controls, instruments, and actuators. Data centers, the 5G infrastructure, and communication systems also rely on complex circuitry requiring protection. Each system must operate continuously despite voltage surges and spikes from lightning, solar events and […]
SiC power modules include dual-diode, full-bridge, phase-leg, dual-common-cathode and 3-phase bridge versions
Demand continues to rapidly grow for Silicon Carbide (SiC)-based systems to maximize efficiency and reduce size and weight, allowing engineers to create innovative power solutions. Applications leveraging SiC technology range from electric vehicles and charging stations to smart power grids and industrial and aircraft power systems. Microchip Technology Inc. announced its expanded portfolio of smaller, lighter […]
PoE chipset delivers 90 W over Ethernet cable
As the industry adopts the latest generation of PoE technology for managing data and power over a single Ethernet cable, users face the challenge of making pre-standard powered devices (PDs) work alongside new IEEE 802.3bt-2018-compliant PDs in an existing Ethernet infrastructure. Many proprietary solutions were brought to market through 2018 that support specifications such as […]
Specialized diodes, Part 1: Tunnel, Zener/Avalanche, and Schottky diodes
There are diode varieties which do much more than just block current flow in one direction and allow it in the other; some of these special diodes have favorable attributes while others are essential in modern electronics. Every electronic engineer is familiar with the diode: it’s a basic, widely used, two-terminal semiconductor device. The diode’s […]
