Infineon  is in volume production of its  OptiMOS 7 40V MOSFET family for automotive applications and they can be ordered in August. They combine 300 mm thin-wafer technology with innovative packaging and are  suitable for standard and future automotive 40V MOSFET applications, such as electric power steering, braking systems, disconnect switches new zone architectures. OptiMOS 7 is also aiming at ...

Infineon Technologies has integrated 600V GaN HD-GIT (hybrid-drain-embedded gate injection transistor) manufacturing into its production line. “The portfolio of discrete and integrated power stage devices provides designers with the necessary flexibility to meet their specific needs for industrial applications complying with JEDEC standards JESD47 and JESD22,” said the company. Available in DSO-20-85, DSO-20-87, HSOF-8-3, LSON-81- and TSON-8 packaging, Rds(on) values ...

XL180 a power supply with a 2 x 3in footprint from N2Power, that delivers 180W with convection cooling only – so no fan is required for operation up to 50°C. “They are available in a choice of three different packages to suit diverse requirements: XLO open-frame, XLE enclosed and XLD DIN rail,” according to Luso Electronics, which is stocking the ...

Infineon is aiming at wireless charging at up to 50W with a wireless power transmitter development kit. Called REF_WLC_TX50W_N1, it consists of the reference board, firmware and software utility called the ‘wireless charging configuration utility’. The design is a Qi-compatible transmitter, with an MP-A2 type transmitter coil, that delivers 50W to Infineon’s own receiver (REF_WLC_RX50W_N1) and a proprietary protocol, taking ...

Infineon Technologies is aiming at 1,200V 10kW loads with a family of half-bridge gate drivers for IGBTs and silicon carbide mosfets. Called the 2ED132xS12x family, they are ruggedised by protection against negative voltage transient, shoot-through and automatic (±5%) over-current shut-down, and have under-voltage lock-out. Over-current detection to output shut-down, can be as short at 1μs. The use of a silicon-on-insulator ...

Recom puts a 5W isolated dc-dc converter with a 9 – 36V input range into a 1 x 1inch plastic package – actually 25.4 x 25.4 x 10mm. REC5K-2405SAW/H4, as it will be known, provides a regulated 5V output, at 1A with 18 – 36V inputs – the ‘AW’ in the part number announces this wide (4:1) input range. 4W ...

TDK-Lambda has introduced a series of rugged non-isolated 300W buck-boost dc-dc converters. The RGC series has a 9 to 53V imput range and adjustable output voltages of 9.6 to 48V (8Amax), or 5 to 28V (12.5Amax), depending on version. The idea is to cover 12, 18, 24, 36 and 48V batteries and power sources. Remote shut-down reduces input current to ...

Cosel has launched a fanless three-phase three-wire 3.5kW ac-dc power supply, aimed at world-wide operation from star or delta networks. Called HCA3500TF, the input range is 180 to 528Vac (for nominal 200V and 400V grids), and efficiency is up to 94% (400Vac in, 65V out) – the company puts the latter down to its digitally-controlled switching topology, and internal silicon ...

STMicroelectronics is has chosen an isolated buck converter topology for a 10W dc-dc converter that provides a regulated local primary power rail, plus a moderately regulated isolated secondary power rail. The secondary output, it said, is suitable for powering isolated IGBT, SiC or GaN gate drivers. The IC is called L6983i, and it can operated from inputs across 3.5 – ...

Oriental Motors has introduced sinewave drive vector controllers for its 30 and 50W brushless dc motors, improving speed tracking, reducing audible noise, increasing peak torque (15% for 30W types and 20% for 50W) and adding functions compared with the earlier BLH series of squarewave controllers. The new controllers are called BLH2D (in photo right). “Adopting vector control as the motor ...
