Low voltage power supplies feature a 10-year E-cap lifetime
Expanding the ZWS300BAF series of single output power supplies, TDK-Lambda have announced the addition of 12 and 15V models with active power factor correction (PFC). The power supplies are suitable for applications including industrial equipment, test and measurement and front-end equipment for broadcast and communications.
IGBT is optimised for soft switching applications
Optimised for soft switching applications including induction cooktops and microwave ovens, IR have introduced the IRG7PK35UD1PbF IGBT. The ultra-fast 1400V IGBT expands IR’s family of IGBTs for soft-switching applications to 1400V, extending the power range of induction heating systems.
Dual phase buck controller suits high current applications
Designed to provide a high integrity supply for distributed high power architectures, a dual phase synchronous rectified buck controller has been announced by Diodes Incorporated. Delivering an output current of up to 60A with embedded bootstrapped drivers that support 12V+12V driver capability, the AP3595 ensures high efficiency power conversion.
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.
