2MHz, DC Accurate Synchronous Step-Down DC/DC Controller with Differential Output Sensing & Clock Synchronization
Linear Technology introduced the LTC3833, a high frequency controlled on-time synchronous step-down DC/DC controller with differential output voltage sensing and clock synchronization. The controlled on-time, valley current-mode architecture forces a very fast transient response by increasing its operating frequency during a transient event, allowing the LTC3833 to recover from a large load step in only a few cycles. Its 4.5V to 38V input range ...
PCB transformer series goes up to 55VA
The Marscher range of PCB mounting transformers is now available from Blore Bowron Ltd, with many types already available from stock. 77 single secondary transformer types cover the range from 0.5VA up to 55VA in 11 steps, with secondary voltages from 6V up to 24V, and similar number are available with optional twin secondaries covering the same voltages.
UPSonNet launches a UPS Guide to build UPS Strategy for Power Protection
A Three Phase On Line UPS systems Strategy for current and future UPS Protection level and UPS Size growth requirements is needed to achieve a cost effective Power Protection, which overrides ad-hoc solutions that may become a very expensive future burden.
TI's breakthrough in high-density power solutions for point-of-load design
Texas Instruments introduced two new power management integrated circuits for point-of-load designs that raise the bar for size, power density and performance. TI’s TPS82671 and TPS84620 integrated power solutions ease design and speed time-to-market in portable electronics, communications and industrial applications.
EFE400M digitally controlled medical power supplies from TDK-Lambda
TDK-Lambda EMEA has extended its range of EFE digitally controlled medical power supplies with the introduction of the 400W, EFE400M Medical range. Combining a 4kVac reinforced input-to-output isolation with dual fusing and an output-to-ground isolation of 1500Vac, the EFE400M meets EN/IEC/UL/CSA 60601-1 safety approvals for medical equipment, making it suitable for use in B (body) and BF (body floating) type medical applications.
3300W DC Power Supplies from Safety Power Group
Industrial and programmable power supply specialist, Safety Power Group, has introduced a new range of 3300W 19in DC power supplies that offer excellent dynamic response to load changes and are designed for long life at full power.
CUI Releases 400 W DC-DC Converter with Integrated Heat Sink
CUI Inc’s power line, V-Infinity, announced the release of a new line of rugged DC-DC converters that provide 400 W of output power. The VFK400 series is a chassis mount solution measuring 7.8” x 5.0” x 1.5” and includes an integrated heat sink for improved thermal performance. The aluminum heat sink allows the unit to operate at higher temperatures with a minimal amount of air flow.
Premo - 1000 Amp Reactor
Power Electronics is continuously demanding higher currents in wound components. Premo enlarges its portfolio of inductive components for Power Electronics by a full deployment of a Catalog to be launched this year, including single and three phase, transformers and reactors, current sensors and filters for currents as high as 2000 Amps.
Low Input Voltage Synchronous Step-Down DC/DC Controller Drives 5V Logic Level MOSFETs for High Efficiency
Linear Technology announced the LTC3852, a low/wide input voltage (2.7V to 5.5V or 4V-38V) synchronous step-down DC/DC controller. The device's onboard charge pump provides 5V bias to drive low RDS(ON) and standard logic-level power MOSFETs from a 3.3V nominal supply. Since the LTC3852's internal charge pump and DC/DC controller are independent, the charge pump output can provide 5V to power the internal gate drivers, and the DC/DC converter pow...
Intersil - Multi-Cell Li-ion Battery Monitor for Hybrid and Electric Vehicle (HEV/EV) Applications
As part of its new HEV/EV system solution, Intersil today introduced a second device that provides a 12-channel automotive grade Li-Ion battery fault and safety monitor. To address the safety requirements of an HEV/PHEV(plug-in hybrid)/EV Li-Ion battery system, the ISL78601 provides independent and redundant fault monitoring when used in conjunction with the ISL78600 battery management system (also introduced today, see related news release).
