FDK DC/DC Converter Comes In SIP Package FDK has extended its DK Series of non-isolated, point-of-load (POL) DC/DC converters with the FPDK12TR8006PSV converter in a low-profile single-in-line (SIP) package. The converter delivers up to 6A of output current at a power density exceeding 950W/in3. It has an efficiency of up to 93 per cent and provides a complete power-conversion solution without the need for external input and output capacitors. The converter is designed for a range of telecommunications, data-communications, computing, industrial and consumer applications where board space, cost, profile, efficiency and reliable operation in elevated temperature environments are critical. The FPDK12TR8006PSV is offered in a 0.394 x 0.220in (10.0 x 5.6mm) SIP package, with a height of 0.472in (12.0mm). Its low profile makes it particularly suitable for high-density racks, blade systems and consumer applications with limited board-to-board and board-to-case clearances. The converter...

Murata Expands Okami Range Of PoL DC/DC Converters Murata Power Solutions has added a miniature 3A, SIP model to its Okami family of non-isolated point-of-load (PoL) DC/DC converters. The OKR-T/3-W12-C provides a solution for designs that require a wide input-voltage range. It offers a high-efficiency PoL solution where board space is limited. Typical applications include datacom routers and servers, industrial equipment such as light-emitting-diode (LED) signage, point-of-sale (PoS) systems and power amplifiers, where the new DC/DC converters are able to provide a cost-efficient way to meet the onboard power needs of ASICs, FPGAs, microprocessors and communications ICs. The new addition to the Okami range has an input-voltage range of 4.5VDC to 14VDC (12VDC nominal) and a programmable output voltage from 0.591VDC to 6.0VDC. Despite overall dimensions of just 10.4mm (0.41in) x 16.5mm (0.65in) x 10.2mm (0.40in), the OKR-T/3-W12-C is said to achieve good thermal derating performance....

DC/DC LED Drivers Launched By Powerpax UK Powerpax UK has announced the launch of the PLC24AH range of dimmable, constant current, DC/DC LED drivers. The PLC24AH series provide a step-down constant current source for driving high-brightness LEDs. Standard output currents include 300mA, 350mA, 500mA, 600mA and 700mA, making these drivers compatible with a range of LEDs and applications. The output voltage range for these drivers is 2-32VDC and all models feature continuous short-circuit protection. These products have a compact size and operate without the need for external components. They provide a high-efficiency solution (up to 95 per cent) for LED driving in both standard and dimming applications. Dimming is achieved through use of an industry standard PWM method - the PWM input is specified to operate between 0.2-10Khz. If dimming is not required, the PWM input doubles as a remote On/Off input. This series has an operating temperature range of -40C to +71C (minimum). These dri...

DC/DC Converter Launched By Ericsson Ericsson Power Modules's BMR454 DC/DC converter delivers double the power of most conventional eighth-brick modules, a wide input range of 36-75V, and a tightly regulated output. The BMR454 eighth-brick family delivers up to 240W with an efficiency rating up to 95 per cent at full load, and a PMBus interface is included. The parameters of the BMR454 can be monitored via PMBus, and they can also be adjusted - by the customer or Ericsson - into an endless number of combinations. The module can be used as an intermediate bus converter (IBC) in front of a range of regulators, or as a traditional DC/DC module powering applications such as hard drives, fans and others. Important application areas are 48V information and communication technology applications such as radio base stations, servers, routers, and a range of systems powered by 48VDC. The modules can be used for improved system efficiency, as output voltage and other parameters can be adj...

DC/DC Converter For GSM And GPRS Cards Linear Technology has announced the LTC3125, a 1.6MHz current mode, synchronous boost DC/DC converter with an accurate and programmable average input current limit. Its internal 1.2A switches can deliver output voltages as high as 5.25V from an input voltage range of 1.8V to 5.5V, making it ideal for Li-ion/polymer, 3.3V PC card slot or multi-cell alkaline/Nimh applications. The LTC3125 can deliver up to 500mA of continuous output current (at 5V) from a 3.3V input. The LTC3125's average input current limit can be programmed between 200mA and 1000mA with +/- 5 per cent accuracy. The accurate adjustable current limit combined with an output reservoir capacitor makes the LTC3125 ideal for applications such as GSM and GPRS cards, which demand 2A or higher current pulses from a power-limited input source. In addition, the LTC3125's accurate input current enables safe and fast charging of large super- or ultra-capacitors in battery backup sy...

XP Offers JHM Low-Power Isolated DC/DC Converters XP Power's JHM ultra-compact low-power isolated DC/DC converters are available in 3 and 6W board-mounted variants and packaged in an industry-standard 24-pin DIP package. They conform to the international medical-equipment safety standards UL / IEC 60601-1 and CSA-C22.2 No 601.1. The units provide 3,000V AC input to output isolation for up to one-minute - meeting the secondary-isolation requirements for BF and CF applications - and 5,000V AC isolation of up to 10 milliseconds for defibrillation proof compliance. Any medical appliance that may involve patient-contact needs to provide isolation from hazardous voltages and have an extremely low leakage current. The JHM series features a small leakage-current of 2uA and low 20pF input to output capacitance. It provides a reliable and cost-effective solution for designers of medical equipment. The JHM series comprises of 20 models. The 3 and 6W units are available in +12V DC or +24...
