Linear Technology has announced the LTC3549, a high efficiency, 2.25MHz, synchronous buck regulator that can deliver up to 250mA of continuous output current from input voltages as low as 1.6V. Using a constant frequency and current mode architecture, the LTC3549 operates from an input voltage range of 1.6V to 5.5V, making it ideal for single cell Li-Ion, or dual-cell alkaline/NiCad/NiMH applications. It can generate output voltages as low as 0.6...

TTi (Thurlby Thandar Instruments) has updated its QL series of laboratory power supplies to include a number of improvements including the latest safety binding post terminals. The QL series is a range of high-performance linear regulated power supplies offering unusually high levels of precision and stability. Setting resolutions of 1 mV and 0.1 mA are provided, and output ripple and noise are below 0.35 mV peak-to-peak. Single and triple output...

Powerstax plc has been selected to supply a turnkey power solution to EcoLEDLighting, market leaders in LED lighting systems. EcoLEDLighting has recently launched it new Part L Compliant, fully dimmable MR16 lamp replacements, which reduce heat output by 80% and use 75% less energy. To enable the company to develop prototypes into production designs, EcoLEDLighting went looking for a power supply company that was able to fulfil the specific requi...

New from Excelsys Technologies is the Xcite 1200W modular power supply. Just 1U high and 260mm x 127mm the Xcite boasts industry leading 15W/in² power density with up to 90% efficiency and an innovative “plug and play” architecture which allows users to configure a custom power solution in less than 5 minutes.

Linear Technology has announced the LT3476, a 2MHz DC/DC converter designed to operate as a four channel constant current LED driver. Each channel of the LT3476 can drive up to eight 1A LEDs in series, enabling the LT3476 to drive up to 32 1A LEDs while delivering efficiencies up to 96%. Each of the four channels is operated by an independent True Color PWM signal, enabling each channel to be dimmed independently to ratios as high as 1000:1.

Now available from MicroPower Direct, the HF60W-SL is a family of compact 60W AC/DC power supplies. These single output units offer 60W of output power, compact packaging, high performance features, EN60950 approval, and CE certification at a very low cost.

Now available from MicroPower Direct, the LF200S series is a family of 2W DC/DC converters in an ultra-miniature SMT case. These converters provide a unique combination of power, performance, miniature SMT packaging and low cost.

AnalogicTech’s AAT1210 is a high power, high current step-up converter for thin, small-footprint portable applications. Supplying up to 4.5W of power, the converter is the first to take a single-cell Lithium-ion battery voltage and boost it to a 5V/900mA output in a total solution less than 1mm in height.

Power Integrations has extended its DPA-Switch DC-DC IC family with the introduction of the 10W DPA422, which enables designers to develop efficient power supply designs for Power Over Ethernet (PoE) applications, and is especially suitable for Class 2 PoE implementations for applications such as VoIP telephones.

Power-One and Micrel have jointly announced availability of the full line of Z-One compatible low dropout (LDO) regulators. The Companies also jointly announced that Micrel had become the newest member of the Z-Alliance of power supply and semiconductor manufacturers offering products and components for the Z-One digital power architecture.
