Recovery rectifiers operate at +175 degrees C
The new FRED Pt recovery rectifiers from Vishay are available through TTI in Europe. With their fast and soft recovery characteristics, low leakage current, and low forward voltage drop of 0.93V, the components reduce switching losses and over-dissipation in automotive and telecom applications, e.g. DC/DC converters in engine control units (ECU), antilock braking systems (ABS), LED lighting and telecom DC/DC bricks.
Regulators impress with low dropout & transient performance
Intersil has announced two high performance, single output LDO voltage regulators that provide best-in-class dropout and transient performance for noise sensitive loads. The ISL80510 and ISL80505 deliver 1 and 0.5A of continuous output current and ultra-low dropout of 130 and 45mV at full load, respectively. The ISL80510's maximum dropout is nearly 50% lower than the nearest competitor, which enables lower power dissipation in industrial, wired a...
MCUs balance power consumption with processing demand
The latest STM32L4 32-bit microcontrollers from STMicroelectronics are in stock at distributor Mouser Electronics. The ultra-low-power microcontrollers are based on the ARM Cortex-M4 32-bit RISC core operating at a frequency of up to 80MHz. The microcontrollers leverage ST’s low power technologies including voltage scaling to balance power consumption with processing demand and include seven low-power management modes to give designers flex...
How custom design can be cost-effective
A surprising number of power supply buyers and specifiers who would benefit from following the custom-design route choose not to for perceived cost and time reasons, argues Tim Worley, Powerstax
DC/DC converters are offered in a SIP-8 package
The world’s first DC/DC converters offered in a SIP-8 package has been released by Power Sources. The TMR 9 and TMR 9WI series provides an isolated and regulated output voltage delivering 9W of output power to our TRACO Power portfolio.
DC/DC converters operate from 200 to 425VDC
TDK has announced an extension to the PH-A280 series of high voltage inputDC/DC converters. Capable of operating from 200 to 425VDC, the new 3.3, 15 and 28V output power modules are suitable for use in data centres, telecomms and renewable energy applications utilising a 380V nominal high voltage DC bus.

LLC resonant controller features synchronous rectification
Claimed to provide best-in-class efficiency for isolated DC/DC converters, Fairchild Semiconductor has launched an advanced LLC resonant controller with Synchronous Rectification (SR). The unique features and superior efficiency of the FAN7688 enables manufacturers to improve the reliability and efficiency of the power supplies for server, telecomms, industrial, PC and TV applications.
Generator IC's low-noise & ripple suits sensitive circuits
Linear Technology Corporation announces theLT3095, a dual-channel IC delivering two very low noise, low ripple bias supplies from a single input. Each channel incorporates a monolithic step-up DC/DC converter post-regulated by an integrated ultralow noise and high PSRR (power supply rejection ratio) linear regulator.
Small DC/DCs present full-size design challenges
Why would OEMs consider developing DC/DC converters in-house when it is no easier than designing an AC/DC SMPS, asks Andrew Leake, Dengrove Electronic Components
