The world's first recycled batteries
Energizer has challenged what was thought impossible in the battery industry with its latest breakthrough, Energizer EcoAdvanced, the world’s first AA battery made with 4% recycled batteries. Energizer EcoAdvanced is Energizer’s highest performing alkaline battery and powers consumers’ most critical devices with less impact on the planet.
120W planar transformers suit active clamp forward topology
Optimised for active clamp forward converters, including use in PoE PSE and pre-standard PD devices, Coilcraft has introduced the PoE120PL series of high-efficiency planar transformers. The series is suitable for 60-120W applications such as thin clients, monitors, industrial Ethernet, IPTV, building management, nurse call systems, point-of-sale terminals and information kiosks. They are also suited for 90W PoE++ PDs.
Buck regulator offers industry-high power conversion efficiency
Analog Devices has introduced an ultralow power buck regulator that extends battery life in portable devices by achieving the industry’s highest ultra-light-load power conversion efficiency. With a 90% efficiency rating and consuming only 180nA quiescent current, the ADP5301 buck regulator is designed to deliver maximum power for a longer period of time than previously achievable.
Continuous 225W at natural convection
A series of AC/DC single output open frame converters for in-design in medical type BF applications has been released by Powerbox. The OFM225 is designed for a continuous output power of 225W at natural convection and 40ºC ambient temperature, increasing to 325W continuous at 12 CFM forced air cooling.
Switching AC/DC power supplies target space critical applications
Designed for space critical applications in consumer appliances, instrumentation and communication equipment, the AAF-03 series of 3W switching AC/DC power supplies in an encapsulated PCB Mount package has been introduced by MINMAX.
Battery pack monitor protects & balances cells
Intersil has announced the ISL94203 3-to-8 cell battery pack monitor that supports Li-ion and other battery chemistries used in medical mobility carts, wheelchairs, e-bikes, handheld power tools, vacuum cleaners and solar or renewable energy storage systems. The device accurately monitors, protects and cell balances rechargeable battery packs to maximise battery life and ensure safe charging and system operation.
Temperature controller operates from -40 to +250°C
A temperature controller that creates a seamless transition between heating and cooling devices, as it serves as the commander of thermoelectric modules, has been introduced by Oven Industries. The 5R7-001 features a bi-directional or unidirectional H-bridge configuration.
Battery monitoring LSI offers 25μA current consumption
LAPIS Semiconductor, a ROHM Group company, has recently announced the development of a 10-cell lithium-ion battery monitoring LSI that provides a current consumption of only 25μA (typ.), the lowest in the industry, making it suitable for battery protection systems in cordless vacuum cleaners, electric tools, and other portable equipment.
Single-output DIN-rail power supplies provide up to 96W
Powersolve has introduced a family of 10 to 96W DIN-rail power supplies designed for installation on DIN rail TS35/7.5 or 15. The PDN10, 20, 40, 60 and 100 series are high efficiency, high reliability power supplies that will operate from a universal 88-264VAC input.
Li-ion battery monitoring LSI delivers a current consumption of 25μA
A 10-cell Li-ion battery monitoring LSI that provides a current consumption of only 25μA, which is claimed to be the lowest in the industry, has been introduced by LAPIS Semiconductor. Suitable applications include battery protection systems in cordless vacuum cleaners, electric tools, and other portable equipment.
