By Eric Persson, Senior Principal Engineer AC-DC Applications, Infineon Technologies We take motors for granted – they have been with us since Benjamin Franklin experimented with electrostatic types nearly three hundred years ago – but the days are long gone when they were controlled in a simple on/off way. Motors in today’s applications, from clothes […]
Power Electronic Tips
GaN power amplifiers deliver high RF output, ensure signals retain characteristics
Satellite communication systems use complex modulation schemes to achieve the blazingly fast data rates required to deliver video and broadband data. To attain this, they must deliver high RF output power while simultaneously ensuring the signals retain their desired characteristics. The new GMICP2731-10 GaN MMIC power amplifier announced by Microchip Technology Inc. helps meet both of these requirements. […]
Glitch-free power supervisor IC protects low-voltage IoT apps
Designers can now enhance system reliability in low-voltage IoT applications with the Essential Analog MAX16162 nanoPower supervisor with glitch-free power-up from Maxim Integrated Products, Inc. This supervisor IC is the industry’s first to fully assert a system reset through the entire system power supply ramp; thereby eliminating low-voltage glitches during power-up and delivering higher system reliability. […]
Thyristor array and steering diode combo protect circuits in devices with high-speed data interfaces
ProTek Devices has introduced two new ultra-low capacitance (< 3 pF) low leakage current (< 10nA) thyristor array and steering diode combination devices for circuit protection in consumer entertainment and networking devices like set-top boxes and modems. They specifically provide surge protection in high-speed data interfaces. ProTek Devices’ TRV24-4LC and TRV24-2LC are also ideal […]
LED drivers designed to enhance performance of connected lighting systems
ON Semiconductor has announced two new devices designed to enhance the performance of connected lighting systems. The NCL31000 and NCL31001 LED drivers to allow manufacturers to develop LED luminaires with light-based positioning technology and visible light communication. By adding data intelligence and accurate positioning (up to 30 cm), these solutions will revolutionize lighting in a […]
Single-channel interface ICs integrate Type-C/PD controller element
In order to strengthen its portfolio of devices supporting USB power delivery, FTDI Chip has unveiled the FT23xHP series. These compact, streamlined interface ICs are supplied in QFN packages. They support operation across just one channel, thereby enabling systems that are subject to space or budgetary constraints to still benefit from elevated levels of power […]
SMD ac/dc supply IC carries 1,700-V SiC MOSFET
ROHM Semiconductor introduced the industry’s first* AC/DC converter ICs with a built-in 1700V SiC MOSFET (BM2SC12xFP2-LBZ) in the TO263-7L package. The devices are optimized for industrial applications focusing on auxiliary power supplies for street lamps, commercial air-conditioning systems, general-purpose inverters, and AC servo drives. An auxiliary power supply is an essential and vital part of industrial applications […]
Sager Electronics to carry Traco Power TSR 1.5 E series dc/dc converters
TRACO Power’s TSR 1.5 E series of non-isolated DC/DC converters is a 1.5-A step-down switching regulator and drop-in replacement for inefficient LM78xx linear regulators. The TSR 1.5E comes in a compact SIP-3 open frame package and offers three available output voltages – 3.3, 5.0 and 12 Vdc. With a full-load operation up to 60⁰C ambient […]
PoE++ transformers can provide up to 95 W
Würth Elektronik expands its MID-POE Power over Ethernet transformer series to include PoE++. These SMT transformers are suitable for Flyback or Active Clamp Forward power supplies that comply with the IEEE 802.3bt (four-pair power over Ethernet, 4PPoE, also known as PoE++) standard. The ten new transformers can provide an output power of up to 95 […]
Tiny eGaN FETs target BLDC motor drives, Lidar apps
EPC advances the performance capability while lowering the cost for off-the-shelf gallium nitride transistors with the introduction of EPC2065 and EPC2054. The EPC2065 is an 80 V, 3.6 mΩ, 221 Apulsed eGaN FET in a 7.1 mm2 chip-scale package. The small size and superior efficiency reduce overall power system size and weight and make it […]
