Step-down DC/DC boosts efficiency in portables June 03, 2015 Step-down DC/DC boosts efficiency in portables Claiming typical efficiencies greater than 95%, the AP3403 step-down DC-DC converter from Diodes Inc., for smartphones and other low-voltage portable products, is a synchronous PWM device that drives a load at up to 600 mA. Read more Micro-module regulators can serve latest FPGAs with up to 144A May 29, 2015 Micro-module regulators can serve latest FPGAs with up to 144A LTM4630-1 is a dual 18A or single 36A µModule (micromodule) regulator with high precision DC and transient output regulation, that is scalable up to currents of 144A, for 28nm and sub-28nm FPGAs, ASICs and microprocessors. Read more LDO targets small consumer devices and wearables May 29, 2015 LDO targets small consumer devices and wearables Semtech has added a low dropout regulator platform for small form factor consumer applications; SC563LHULTRC is a dual output LDO in an 8 pin MLPD package measuring 1.6 x 1.2 mm. Read more GaN power transistors widen performance range May 28, 2015 GaN power transistors widen performance range Efficient Power Conversion Corporation (EPC) has introduced two eGaN FETs to raise the bar for power conversion performance in a variety of applications including DC-DC converters, synchronous rectification in DC/DC and AC/DC converters, motor drives, LED lighting, and industrial automation. Read more GaN power transistor fits into 5.0 x 6.5-mm footprint May 27, 2015 GaN power transistor fits into 5.0 x 6.5-mm footprint GaN Systems has confirmed the development of the world’s smallest 650 V, 15 A gallium nitride transistor which has a footprint of 5.0 x 6.5 mm making the component 50% smaller than competing devices. Read more Farnell to stock Murata's ultra-compact 1W converters May 27, 2015 Farnell to stock Murata's ultra-compact 1W converters Farnell element14 has introduced Murata’s new NXE1 series of cost-effective 1W Isolated DC/DC Converters into its product lines. With a profile 30% lower than the 7mm height industry norm, the unit is well suited for designs where space constraint is an issue. Read more 60V step-down controller can eliminate intermediate power buses May 26, 2015 60V step-down controller can eliminate intermediate power buses Intersil’s ISL8117 is a 60V synchronous buck controller that can simplify power supply and distribution design; allowing for buck conversions such as 48V direct to 1V – through a very low minimum-on-time-specification – it can permit point-of-load supplies to be fed from 48V rails. ... Read more 48V regulators deliver 100W from a 1-cm-square package May 25, 2015 48V regulators deliver 100W from a 1-cm-square package Vicor has added to its Picor Cool-Power ZVS regulator range with 48V buck regulators that enable direct stepdown from 48V distribution buses to point-of-load with high efficiency. Vicor says that these device increase flexibility for designers and power system architects; as well as regulated-voltage ... Read more Infineon takes CoolMOS to generation 7; halves switching losses May 25, 2015 Infineon takes CoolMOS to generation 7; halves switching losses Infineon Technologies’ C7 series superjunction (SJ) MOSFETs is a 600 V series that claims 50% reduction in turn-off losses compared to the CoolMOS CP, offering a GaN-like level of performance in PFC, TTF and other hard-switching topologies. The company also presents it as a transition to forthcoming ... Read more Digital power chipset optimises dead time automatically May 22, 2015 Digital power chipset optimises dead time automatically Texas Instruments has introduced a power management chipset that includes intelligent digital control and a body-diode sensing feature to optimise secondary-side synchronous rectification in next-generation AC/DC and isolated DC/DC power supplies.
