Fully encapsulated dual power modules offers high power density
Renesas Electronics has announced two new fully encapsulated digital DC/DC PMBus power modules that deliver the highest power density and efficiency in their class. The dual ISL8274M operates from a 5V or 12V power rail, provides two 30A outputs and up to 95.5% peak efficiency in a compact 18x23mm2 footprint.
Buck-boost converter offers 1.3x longer battery life
A buck-boost DC/DC converter with built-in MOSFET has been developed by ROHM, featuring what it claims to be the lowest current consumption in the industry. As a result, it is suitable for electronic devices powered by batteries such as electronic dictionaries, remote controls for home appliances, and items such as toys, and other portable electronic devices.

Axial lead fuse optimised for protecting wall-mounted chargers
Littelfuse covers the 777 Series axial-lead 3.6x9mm fuse designed to protect electronic appliance chargers from overcurrents. The robust design lets the device withstand up to 24 hits of a 7.5kV ringwave surge.
Axial lead fuse provides battery charger protection
The axial lead 3.6x9mm 777 series fuse from Littelfuse is designed for overcurrent protection in electronic appliance charger applications. The robust design enables the device to withstand up to 24 hits of 7.5kV ringwave surge; it will open safely on a direct short condition without producing body ruptures and soot phenomenon.
Power semiconductors deliver high energy efficiency
Two ranges of power semiconductors from Power Integrations are in stock at RS Components. Delivering high energy efficiency with integrated protection features, these are the LinkSwitch-TN2 family of offline switcher ICs and the HiperPFS-4 family of power factor Correction (PFC) ICs.
9W in a SIP-8 package provided in DC/DC converters
Additionally offering its proven PMBW and PMB DC/DC converter series with up to 9W of output power, PEAK electronics has increased the components from being previously available with just 1W, 2W, 3W and 6W. In addition, both series of converters are now available in SIP-8 packages, meaning a space saving of almost 50% compared to the DIP-24 packages offered so far.
DC/DC converters designed for vehicle and rail applications
Specially designed for applications in vehicle and rail technology, MTM Power has introduced the primary switched DC/DC converters PCMDS150WK-IP65, which are also for use in industrial and telecommunication applications. The push-pull topology used while developing these converters enables a wide input voltage range with high efficiency.
