AC/DC supplies deliver shock resistant performance
Sealed in a heat conducting potting material, the TER family of AC/DC power supplies has been expanded to include 500W and 600W models. The power supplies, from Schaefer Inc, feature an ultra-wide temperature range of –50ºC to 85ºC, making these units suited for projects that demand reliable and shock resistant performance in the harshest operating conditions.
DC/DC converter for battery powered applications
Featuring an integrated coil to simplify board layout and minimise any unwanted radiated noise, the XCL101 series step-up micro DC/DC converter has been announced by Torex Semiconductor. Able to start operation from input voltages as low as 0.9V, the XCL101 is suitable for use with single alkaline or nickel metal hydride cells.
Driver boasts 10mm clearance & external creepage distance
Designed for motor drives, alternative energy, welding equipment, and other high working voltage applications, the VOW3120-X017T is a IGBT and MOSFET driver from Vishay Intertechnology. The VOW3120-X017T features a minimum 10mm clearance and external creepage distance.
Dual IGBT Gate Driver is suited for driving SiC MOSFETs
A Dual IGBT Gate Driver, featuring two high current outputs, has been announced by IXYS. The IX2204 driver's high current outputs are capable of sourcing 2A and sinking 4A. Manufactured on IXYS ICD's advanced BCDMOS Silicon on Insulator (SOI) process, the IX2204 outputs have a wide operation voltage range of -10V to +26V.
Power supply suits 98% of CompactPCI Serial applications
Retaining the familiar form factor from CompactPCI (19", 3 U and 8 HP), the CompactPCI Serial PSU has been introduced by Schroff. Collaborating with major board manufacturers, system customers and PSU manufacturers, Pentair has created a 'quasi' standard for pluggable Schroff CompactPCI Serial PSUs and developed a first AC PSU with a wide input voltage range.
700W L-Band RF power transistor reduces part counts
Lowering part counts to reduce system cost, improve reliability and maintain high ruggedness, a 700W L-Band RF power transistor has been introduced by Infineon Technologies. The company has claimed that the PTVA127002EV features the industry's highest L-Band output power (700W) available for radar systems operating in the 1200-1400MHz frequency range.
Robust current sensing IC improves system efficiency
Increasing overall system efficiency and saving space in high current applications, a robust general purpose current sensing IC has been introduced by International Rectifier. The IR25750 uses the Rds(on) of a power MOSFET or the VCE(on) of an IGBT to measure current, eliminating the need for large external current sensing resistors.
Digital PWM controllers for next-gen computing platforms
Significantly improving efficiency and reducing board space and component count, International Rectifier has launched highly versatile, PMBus enabled, CHiL digital PWM controllers and integrated PowIRstage solutions. These are suitable for a variety of mid-range to high-end server, desktop and computing applications.
Space-saving packages for regulator transistors
Designed for 48V circuits in networking, telecomms and PoE equipment, Diodes Incorporated announce new space-saving package options for its ZXTR2000 series of high-voltage linear regulator transistors. Device inputs are actually tolerant up to a maximum of 100V, meaning all regulator transistors offer plenty of headroom in the event of transient over-voltage conditions.
Small load switch features very low on-resistance
Featuring controlled turn on and very low on-resistance, the APE8937-HF-3 load switch has been announced by Advanced Power Electronics. The load switch contains one N-channel MOSFET that can operate over a wide input voltage range of 0.8-5.5V and support a maximum continuous current of up to 4A.
