LED and Lighting Design solutions addressed at free forum
Motiv8 Solutions is building a strong seminar programme for its LED and Lighting Design Forum on March 25 at the Williams F1 Conference Centre near Oxford. Speakers already confirmed will address LED drivers, design support tools for power management, LED lifetimes and reliability and LED driver EMI considerations. In the bench top exhibition alongside the Forum a strong line up of suppliers and distributors will field LED lighting applicat...
Regulators address multiple voltage rail requirements
Suitable for complex industrial and medical systems, the ISL85410 and ISL85418 synchronous buck regulators down-convert the DC voltage from a power supply or battery to power multiple microprocessors and board components. This conversion can occur at various voltage requirements and helps to minimise power loss.
Power switch driver boasts operates at extreme temperatures
An intelligent power driver for SiC, GaN and silicon power switches has been announced with the company, X-REL Semiconductor, claiming the device is the industry's first power switch driver able to operate at extreme temperatures. The monolithic, isolated, intelligent power driver is targeted at motor drive, power conversion and high-voltage communication applications.
Significantly reduce charge times in USB AC/DC wall chargers
Using the company's intelligent rapid charge digital algorithm and digital primary-side control technology, the iW1680 AC/DC rapid charge controller can significantly reduce charge times in USB AC/DC wall chargers with no bill of materials cost premium over slower conventional charging technologies.
150W DC/DC converters suit distributed power architectures
Designed for intermediate bus and distributed power architectures, Murata's UEE series is a range of 150W isolated DC/DC converters. Packaged in an industry standard eighth brick format, these DOSA compliant converters measure just 58.4 x 22.9 x 10.7mm and are available with either mounting pins or as a surface mount device.
Switch saves 91% PCB space over discrete MOSFETs
Designed to save 91% PCB space compared to when using discrete MOSFETs, the SiP32101 is a 6.5mΩ bidirectional battery switch from Vishay. The device, featuring slew rate control, is designed for low-voltage battery isolation in portable electronics, healthcare devices, and instrumentation.
DC/DC converters boast high 7A current for monitors & TVs
A pair of synchronous DC/DC buck converters has been launched for use in applications such as monitors, TVs and STBs. The AP65500 and AP65400, from Diodes Inc, deliver continuous load currents of 5A and 4A respectively, peaking at 7A at an efficiency as high as 96%.
IGBT is optimised for induction cooking applications
Focusing on system efficiency and demanding reliability requirements for induction cooking applications, the 20A RC-H5 IGBTs have been announced by Infineon Technologies. The 1350V Reverse Conducting (RC) soft switching IGBT provides up to 30% reduction in switching losses compared to previous generations.
MIL-STD-810F compliant AC/DC supply delivers up to 780W
A series of fan-cooled, rugged AC/DC power supplies has been launched, designed for heavy-use industrial applications where a more robust unit is required. The HHP650 series, from XP Power, can accommodate an extended voltage input range from 85 – 305VAC and deliver up to 780W at high line input.
DC/DC converter offers 10-33V output for RFPA applications
Designed to power radio-frequency power amplifier (RFPA) applications, Ericsson Power Modules has introduced the PKU4116C DC/DC converter. Offering an ultra-wide adjustable output voltage of 10-33V (meeting the specifications as defined by the Antenna Interface Standards Group (AISG)), the converter delivers power up to 100W and an output current of 3.3A.
