Powersolve has announced a wide selection of external power supplies designed specifically for use with medical equipment. Made up of five product families, the new medically approved power supplies all meet UL, cUL2601-1 and EN60601-1 safety approvals and EMC standards to EN55011 or EN55022 “B” and FCC”B”.

Schaefer, Inc. has introduced the IEXR and IEHR Series’ of rugged 70W-150W dc/dc converters, which are ideal for a variety of applications, including process control, instrumentation and industrial installations.

Powersolve announces TRACOPOWER’s TMT series of ultra-compact AC/DC power modules with approvals that make them suitable for a wide range of commercial, industrial and medical applications.

Fairchild Semiconductor has introduced a 1200V/15A NPT-Trench IGBT with the ability to withstand as much as 300mJ of avalanche energy in induction heating (IH) applications. This excellent avalanche capability helps ensure “rugged” fail-safe operation of the system during abnormal avalanche-mode conditions that commonly affect IH appliances such as microwave ovens

Texas Instruments has introduced a 1-W, unregulated DC/DC converter in a miniature package that features 3-kV isolation. The new DCH01 family of plug-in power modules operates from a 5-V input and provides single voltages of 5 V, 12 V, and 15 V and complementary dual-output voltages of ±5 V, ±12 V and ±15 V. The tiny modules are ideal for industrial applications such as data acquisition, motor control, programmable logic cont...

The power supply supporting a GSM handset baseband chipset must wake up to full load within microseconds. By integrating a fast transient 600mA step-down converter and a 300mA LDO, AnalogicTech’s AAT2505 forms a complete high-performance power supply solution for GSM handset baseband core and I/O.

Power-One has introduced the F4804A input filter. This RoHS-compliant product is designed to minimize the conducted and radiated emissions generated by switch-mode DC-DC converters to facilitate meeting FCC and EN55022 Class B conducted emissions requirements. When compared to previous generation F4804 products, the F4804A offers increased common-mode attenuation, improved elevated-ambient-temperature performance, and a lower-profile package.

STMicroelectronics has introduced an advanced double-ended controller specifically designed for the series-resonant half-bridge topology. The new-generation high-voltage IC is said to guarantee excellent performance, allowing the design of fully protected and highly reliable power supplies that are particularly suited for use in applications such as Liquid Crystal Display (LCD) and Plasma Display Panel (PDP) TVs, high-end AC-DC adapters for lapto...

PREMA has introduced a white LED driver designed for a variety of applications. The core of the new driver PR4401 consists of a step-up converter with current output, that provides an output voltage of typically 3.6V for white LEDs. The input voltage can be as low as 0.9V, thus allowing a single cell battery operation.

To celebrate the World Cup ThePowerSupplyShop.Co.Uk. is offering the CS4, 24VDC output DIN-Rail power supply for what it calls a “football crazy” price - just £19.66. The very compact CS4 Din-Rail power supply has an input range of 90-264VAC at 50-60Hz and output of 24VDC @ 1A continuous. This low output noise power supply is suitable for SELV and PELV applications, is overload and short circuit protected and has greater than 85% efficienc...
