Miniature Encapsulated AC/DC Power Modules Suit a Wide Range of Applications
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.
1200V/15A NPT-Trench IGBT can withstand as much as 300mJ
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
1W DC/DC Converters with 3-kV Isolation from TI
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...
Step-down converter has fast transient response to meet strict GSM specs
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.
RoHS-Compliant DC/DC Input Filter
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.
High-Voltage IC for Resonant Half-Bridge Topology
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...
0.9V-White LED Driver Requires Just One External Component
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.
ThePowerSupplyShop Celebrates 1966 by offering a DIN-Rail PSU for £19.66
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...
Avago's CoolPAM power amplifiers used by a Leading Handset Chipset Supplier for HSDPA/W-CDMA Reference Design
Avago Technologies has announced that its CoolPAM power amplifier modules have been incorporated in a reference design from a leading W-CDMA chipset supplier. Handsets based on the design will ship beginning this fall, giving manufacturers a time-to-market advantage in delivering the major functionality for multi-mode third-generation (3G) mobile phones, data cards, PDAs and other mobile devices.
Capacitor-free LDO offers One Percent Voltage Regulation Accuracy
Texas Instruments has introduced a series of 1.5-A and 3-A low-dropout linear regulators that feature a one percent voltage regulation accuracy rate over line, load and temperature. The easy-to-use LDOs meet the sequencing requirements for high-current applications such as telecom, notebooks and servers that use FPGAs and TI's digital signal processors (DSPs).
