DC/DC converters keep low profile - 30% lower than industry norm
The new NXE1 series of cost-effective 1W Isolated DC/DC Converters from Murata are now on sale at Farnell element14. With a profile 30% lower than the 7mm height industry norm, the DC/DC converters can be used in designs where space constraint is an issue. Priced from £2.49 and with price breaks for higher quantities, the NXE1is manufactured using automated processes that greatly improve overall product reliability and deliver consiste...
Rugged power inductor series expanded for automotive use
TDK Corporation has expanded its CLF-NI-D series of rugged power inductors for use in automotive electronics. The CLF7045NI-D wirewound SMD power inductors feature high efficiency and reliability over a temperature range of -55 to +150°C and offer rated inductance values from 1.0 to 470μH (E6 series). The CLF7045NI-D types are available for rated currents of 0.41 to 8.5A and offer DC resistance values ranging from 9mΩ to 1.20Ω.
Intelligent-power module targets embedded drive applications
An Intelligent-Power Module (IPM) for low-power operation in embedded drive applications has been introduced by Vincotech. Suitable for embedded motor drives for fans, pumps, washing machines and small industrial motor drives with up to 2kW output power, the three-phase input power module comes in a flow 1B housing with press-fit pins for easy assembly.
Sync-buck controller bypasses intermediate step-down conversion stage
Intersil has introduced its first 60V synchronous buck controller able to bypass the intermediate step-down conversion stage traditionally employed in industrial applications. The ISL8117 synchronous step-down PWM controller’s low duty cycle (40ns minimum on-time) enables the direct step-down conversion from 48V to a 1V PoL.
Neutral point clamped modules feature IGBT H5 technology
A set of Neutral Point Clamped (NPC) modules featuring Infineon IGBT H5 technology have been introduced by Vincotech. Offered in flow 0 and flow 1 housings, the modules combine high speed with low saturation voltages and outstanding switching characteristics.
60W dual redundant hot swap power supplies
Stadium Power has announced the addition of the 60WAC input G1X2 and DG1X2 48VDC models to their range of 1+1 redundant 1U industrial single output and ATX / EPS power supplies. These are optimised for secure bulk power applications including digital imaging, comms systems, industrial PCs and telecomms or broadcast systems.
GaN enables 50% transistor size reduction
GaN Systems has confirmed what it calls the ‘world’s smallest’ 650V, 15A gallium nitride transistor, in the wake of the 2015 PCIM conference in Nürnberg, Germany. With a footprint of just 5.0x6.5mm, the GS66504B - one of a family of 650V devices that spans 7 to 200A - is 50% smaller than competing devices.
Practical guide is available for download
Offered as a practical guide for engineers, power-supply designers and students, the DC/DC book of knowledge is a 234-page publication offered by Recom Power.
Low inductance capacitors operate in high temperatures
Capacitors from SCR Industries, part of the Cefem Industries Group, include a low series resistance and low inductance capacitor, capable of operating at up to 175°C.
DC/DC converter addresses always-on automotive needs
Linear has announced the LT8495, a current mode, fixed frequency SEPIC/boost DC/DC converter with an internal 2A, 70V switch. Quiescent current of only 9µA makes it suitable for always-on automotive systems, and its integrated Power-On Reset (POR) and watchdog timer offer enhanced system reliability required in automotive and industrial applications.
