Secondary side technology targets white goods market
Using the magnetic inductive coupling principle, Power Integrations has introduced the InnoSwitch-EP family of off-line CV/CC flyback switching ICs and shifts focus from the charger market to the white goods market where reliability is expected to be 1pmm.
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 input DC/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.
Power supplies target applications that require high power for a short-duration
A series of 600W switching power supplies featuring single output models (3.0-60VDC) and dual output models (5V/12V, 5V/24V and 12/24VDC), with a broad range of standard options, has been released by ULTRA LEVEL TECH.
Power receiver controller ICs are USB PD & Type-C compatible
ROHM has announced the development of a class of power receiver controller ICs compatible with the latest USB Power Delivery (Rev2.0) and Type-C (Rev1.1) standards. The BM92TxxMWV series supports not only conventional USB power supply up to 7.5W, but the newly expanded power range as well up to 100W (20V/5A) for USB Type-C connected devices.
DC/DC converter offers internal redundancy
The BHR 65X2-4U2NF, a 1kW, convection cooled, DC/DC converter has been released by ABSOPULSE Electronics. The elimination of optical components, low component count, large design room and comprehensive electronic protection contribute to an MTBF of 175,000 hours at 45°C.
Battery cell controllers support low cell count connected applications
Freescale Semiconductor has introduced the MC33772 3- to 6-cell Li-ion battery cell controller, expanding its portfolio of highly integrated and connected solutions for reducing BOM cost, increasing operating robustness and meeting stringent functional safety requirements for automotive and industrial battery systems powering the solid-state Internet of Tomorrow.
IC enables low-power & cost-effective headset detection
Integrating a comparator, OR gate and N channel MOSFET into a miniature package, the AZV5001 headset detection IC has been announced by Diodes Incorporated. The device enables the connection of a headset with microphone to be quickly and simply detected in cost- and power-sensitive consumer electronics such as mobile phones, tablet computers and media players.
Generator IC's low-noise & ripple suits sensitive circuits
Linear Technology Corporation announces the LT3095, 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.
