STMicroelectronics has introduced an advanced high-frequency step-down dc-dc converter particularly suited for use in data-storage applications, such as hard disk drives, DVDs, Blu-ray Discs, High-Definition DVDs, and in portable devices, such as MP3 players and digital cameras, that require high efficiency, small size, and light weight. The new, cost-competitive ST1S06 integrates functions that benefit users with excellent electrical performan...

Semtech has announced the SC194A, a highly integrated 1A DC-DC step-down (buck) regulator with the small size and output flexibility needed for portable device applications. The SC194A has an input voltage range from 2.7V to 5.5V with a focus on portable applications that use Li-ion batteries. The device uses two programming pins to allow users to set the output voltage to 1.0V, 1.2V, 1.5V or 1.8V. These pins can be hard-wired to set a constan...

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...
