Murata Power Solutions’ (formerly known as C&D’s Power Electronic division) new 78SR Series 2A switching regulators provide high operating efficiency for applications requiring 3.3V or 5V outputs, at 2 Amps or less, from 8 to 32V inputs. At a nominal 12V input, full-load efficiencies approach 96% for 5V models, and 93% for 3.3V models.

Lambda has expanded its line-up of the popular DPP Series DIN rail power supplies with the introduction of new 240W models. The DPP240 complements the recently introduced DPP120 supplies, and with typical efficiency reaching an impressive 90%, is suited for use in factory automation, industrial control systems and test equipment applications.

Lambda has introduced the KM Series of medically approved 15 to 40W enclosed PCB mount power supplies with single-, dual- or triple outputs. Eliminating the need for external power adaptors, these small, lightweight power supplies are ideal for use in a wide variety of medical equipment, in particular portable applications such as electronic blood pressure monitors and home infusion therapy equipment.

The new PL Series from TTi (Thurlby Thandar Instruments) is a range of laboratory DC power supplies which offers the benefits of digital technology whilst retaining true analogue controls for voltage and current. The new product range replaces the original PL series, which has become the most widely used power supply range within the UK electronics industry.

Power Integrations has announced the TOPSwitch-HX family of AC-DC power conversion ICs. Power Integrations introduced its original TOPSwitch product in 1994, combining a 700 V switching power MOSFET with controller and supervisory functions into a single monolithic IC. The TOPSwitch-HX family of ICs utilizes Power Integrations’ EcoSmart energy-efficiency technology and combines great standby power performance with constant, high efficiency unde...

Power-One has announced the introduction of the 100kW PVI-100 Series, the first products in the Aurora PVI-Central Family of commercial photovoltaic inverters. The PVI-Central Family employs subracks in a scalable modular architecture that facilitates application-optimized solutions from 50kW to 300kW. These grid-tie systems are designed for large solar applications such as apartment buildings and industrial facilities.

Leading power supply manufacturer, SL Power Electronics Corp, has announced what the company claims to be the industry’s smallest commercial 200W power supply and almost certainly the smallest medically rated 200W power supply available. Units in the GNT200 Series feature a power density of from 10 to13W/in³. “These are bold claims,” says Nigel Davies, SL Power’s European Managing Director, “But three years ago,...

How much battery life do I really have left? Texas Instruments Incorporated (TI) answers the question by introducing its system-side fuel gauge integrated circuit (IC) with Impedance Track™ technology for smart phones and other handhelds. The 2.5 mm x 4 mm gauge predicts battery life with 99-percent accuracy to extend run-time, protect data and provide a better user experience for mobile handheld users.

Intersil’s ISL6228 high-performance dual-output buck controller for notebook peripheral computing applications is capable of operating over the industry’s widest input voltage range (3.3V to 25V) and has a highly flexible output voltage range from +0.6 to +5.0V. These broad voltage ranges, combined with dual independent switchers, make this controller the ideal choice for notebook peripheral applications, as well as a host of general purpose...

Demands for increased power requirements in a limited space, especially in datacom and server designs, have been addressed by the new SC4612 28-volt synchronous buck power converter from Solid State Supplies to enable system designers to increase port density while reducing board size.
