High-side load switch operate from 1.4V to 5.5V with 2.0A max load current
Diodes Incorporated announced the introduction of the AP22913, a 2.0A single-channel, slew-rate-controlled load switch with true reverse current blocking (TRCB) for high-side load-switching applications. Single-channel high-side load switches provide an effective way of applying or removing power to a load, particularly to removable peripherals powered through a USB port. The large output capacitors (100µF) associated […]
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 […]
Optimizing discrete SiC devices
SiC FETs now include measures aimed at keeping losses down while managing fast switching waveforms. Dr. Anup Bhalla | UnitedSiC Silicon carbide (SiC) FETs have low on-resistances, fast switching speeds, and intrinsic diodes with low reverse recovery charge (QRR) and low forward-drop (VF) qualities. These qualities make SiC FETs suitable for use in active-front-end three-phase […]
