AC-DC Architecture Enables 7x Efficiency Lift

Analog Devices (ADI) has announced two nanoPower modules with built-in inductors. The MAXM38643 1.8V to 5.5V input, 330nA quiescent current (IQ), 600mA buck module and the MAXM17225 0.4V to 5.5V input, 300nA IQ, 1A boost module with True Shutdown feature low IQ and deliver more battery life. By integrating a preselected inductor, these micro system-level IC modules (µSLIC) are up to 37% smaller size compared to a standalone IC plus external inductor.

Verizon Taps Infineon AC-DC Tech for USB Charger

Infineon Technologies has announced that its EZ-PD PAG1 AC-DC power solution is used in the recently launched USB-C Fast Wall Charger from Verizon made by Xentris Wireless. The new Verizon charger powers on-the-go devices swiftly and provides up to 45W of super-fast charging with compatible devices.

GaN-Based MMICs Target 5G and SatCom

Microchip Technology has announced a significant expansion of its Gallium Nitride (GaN) Radio Frequency (RF) power device portfolio with new MMICs and discrete transistors that cover frequencies up to 20GHz. The devices combine high power-added efficiency and high linearity to deliver high levels of performance in applications ranging from 5G to satellite communications, commercial and defense radar systems and test equipment.

Build a Power Supply Monitoring and Control System

Switching power supplies are a key piece of gear for many projects. But cost-effective units benefit from some kind of outside means of stepping output voltage up or down. To address that issue, Anuj built a power supply monitoring and control system using an ESP32-based development board.

AC-DC Architecture Enables 7x Efficiency Lift

Eggtronic has announced QuarEgg+, a proprietary power architecture that significantly improves the efficiency and reduces the size of AC-DC converters. According to the company, the new architecture will maximize the performance, minimize the form factor and improve the reliability of AC-DC power schemes in applications ranging from fast chargers to power supplies for loudspeakers and smart home assistants.
