Industry session explores 3D power packaging
At APEC 2014, The Power Sources Manufacturers Association (PSMA) Packaging Committee is sponsoring an industry session, titled: “3D Packaging for Power Electronics”. The session will present proven and available techniques to implement 3D packaging in power supplies today, while speakers from leading research facilities will provide a look into the future.
1W DC/DC converters improves efficiency by up to 8%
A 1W, DC/DC converter series has been launched with the manufacturer, Murata, claiming that the devices offer up to 8% more efficiency than similar devices currently on the market. Two input voltage versions are available from the NCS1 series of regulated, single output DC/DC converters.
DC/DC controller provides efficient gate drive from 2.5-60V
Designed to protect against high voltage transients and continuing operation during automotive cold crank, the LT3840 is a synchronous, step-down DC/DC controller from Linear Technology. It is suitable for applications including 12 or 24V automotive, heavy equipment, industrial control, robotics and telecomms.
MOSFETs offer fast switching and very low on-resistance
Offering fast switching performance and low on-resistance, the AP99T03GS-HF-3 MOSFET has been launched by Advanced Power Electronics.
DC/DC controller delivers 97% efficiency
Replacing rectifying boost diodes with high efficiency N-channel MOSFETs, the LTC3784 high power two phase single output synchronous step-up DC/DC controller has been introduced by Linear Technology. It can produce a 24V output at 10A from a 12V input at up to 97% efficiency without a heat sink.
Two becomes one with high-isolation DC/DC converters
Richardson RFPD is offering availability and full design support capabilities for RECOM Power’s high-isolation DC-to-DC converters. Designed specifically for insulated-gate bipolar transistor (IGBT) systems, the converters' asymmetric outputs of +15V and -9V make them ideal to power IGBT drivers, replacing the need for two converters.
AC/DC offline LED power supply controllers lowers BOM costs
Ismosys has released details of Dialog Semiconductor’s new high performance, 15W single-stage, AC/DC offline power supply controller for dimmable LED luminaires that require high Power Factor (PF), low total harmonic distortion, outstanding TRIAC dimmer capability and low BOM cost.
Wireless charging is on the rise
The proliferation of wireless charging technology throughout Europe has accelerated during the last couple of years, fuelled in part by the increased availability of standardised wireless charging in mobile devices. But which standard will prevail? By Morten Kreiberg Block, Marketing & Engineering Director, Nordic, Arrow Electronics.
DC-DC converters target telecoms, industrial usage
Luso Electronics Distribution now has available SynQor’s high-input-voltage NiQor family of DC-DC converters for a range of industrial and telecom applications. Included within the range is a product that is ideally suited to use in HEVs (Hybrid Electric Vehicles) or in a myriad of portable battery-charging applications such as fuel cell or solar-energy based power generators.
GPIB interface enhances control in multi-channel power supplies
Keithley Instruments has added two multi-channel power supplies with GPIB interfaces to its line of programmable DC power supplies. The new models address the need for greater control and communication flexibility in both R&D and production test applications, which GPIB interfaces can provide. Both the Model 2220G-30-1 dual-channel and 2230G-30-1 triple-channel power supplies combine greater output accuracy and lower prices.
