Microchip has announced the MCP73833 and MCP73834 single-cell, high current (1A), Li-Ion/Li-Polymer linear charge-management controllers. These fully integrated devices combine several key charge-management and safety features in a single chip for reliable charging of high-capacity single-cell Li-Ion and Li-Polymer batteries.

Expanding its point of load (POL) range of DC/DC regulators, Ericsson Power Modules has introduced two POLA devices that are amongst the smallest switching POL regulators available, and provide high efficiency and a host of features for ‘real needs’ applications at low cost.

Schaefer has introduced the AEP-1500 Series of 1500W, low cost, high efficiency, pure sine wave inverters. The “clean” pure sine wave output of the AEP-1500 Series, with less than 3% total harmonic distortion, is ideal for powering sensitive loads and for improving AC equipment performance.

Texas Instruments has announced the availability of the TMS320F28044 digital signal controller targeted at multi-channel point of load applications such as telecommunications and networking infrastructure equipment, servers, laptop computers, and industrial equipment. The new F28044 controller is the industry's only device to offer the ability to manage up to 16 DC/DC converter channels using a single programmable controller with 100 MIPS of DSP ...

Texas Instruments has introduced two new PurePath DigitalT power stages. The TAS5261 provides OEMs with the industry's highest power single-chip digital amplifier power stage, capable of driving more than 300 watts (W) into a 4-ohm speaker, while the two-channel TAS5162 digital amplifier power stage can drive 200 W per channel at 6 ohms and 125 W at 8 ohms. The devices enable higher efficiency and sound quality in a variety of audio applications,...

The A3986 from Allegro MicroSystems Europe is a dual full-bridge gate driver IC with integrated microstepping translator circuitry. The device is suitable for driving a wide range of industrial bipolar 2-phase stepper motors in the 30 to 500 W power range. Motor power is provided by external N-channel power MOSFETs at supply voltages from 12 to 50 V.

Lower switching losses coupled with smaller chip sizes Common terminal height for easy bus-bar connection Wide range of IGBT and input rectifier ratings

Vicor has announced eight mid-power Maxi DC-DC converters to its 24Vdc input family: a 3.3Vout, 200W model and 300W models at 5, 12, 15, 24, 28, 36, and 48Vout. The modules — which incorporate Vicor’s patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) topology — are appropriate for industrial or process control, distributed power, medical, ATE, communications, defence, and aerospace applications. With switching frequencie...

Augmenting its offering of medical ac/dc power supplies, Power Sources Unlimited has announced the MPU50 Series if 50W AC/DC external power supplies. The compact supply measures only 5.75 x 2.99 x 1.69in and features 4000VAC input to output isolation and safety ground leakage current of 0.1mA at 240VAC. Achieved efficiencies are 83% typical and the operating temperature is 0C to 70C, with derating after 50C.

Powersolve, the leading power solutions specialist company, announces the ROAL Electronics RHPS front-end power supply range. Available in both 12 and 48V output versions, the new power sources have been designed for use in distributed power architectures to power high-density DC/DC modules and Point of Load converters (PoLs). As such, they will satisfy a wide range of applications in IT, telecoms, networking and broadcast systems.
