High Efficiency Quad PSE Controller Addresses IEEE 802.3at PoE+ Standard
Linear Technology has introduced the LTC4266, a 4-port Power over Ethernet (PoE) controller for Power Sourcing Equipment (PSE) required to provide IEEE 802.3at (25.5W) or proprietary higher power levels. Next-generation PoE applications call for more power to support demanding features, while increasing power efficiency in an effort to be more green and reduce costs. The LTC4266 provides up to 100W over 4-pair Ethernet cabling and is fully compli...
2 Watt Output Single/Dual Output DC-DC Converters with low output ripple and wide operating temperature range
Martek Power has announced the release of 200UFR dc-dc converters. The 200UFR is a new series of compact, high efficiency (up to 80%) onboard dc/dc converters wrapped in a low profile SIP package. The series consists of 14 models with input voltages of 24V and 48V in 4:1 input range and offers regulated output voltages of 3.3V, 5V, 12V, 15V, ±5V,±12V and ±15V. Low ripple and noise, wide operating temperature range, remote on/...
IGBT modules have internal inductance of just 15nH
SEMIKRON has introduced a low-inductance 1200V SEMITRANS IGBT module series for use in AC/DC converters in the 20 – 300kW power range. These modules are available with Fuji fifth-generation V-IGBT chips as an alternative to IGBT4 chips. The very low 15nH module inductance offers two advantages: 50V higher DC link voltage than in competitor modules, thanks to the lower switching overvoltages; plus faster and softer IGBT switching producing lower...
