On The Shelf Power Integrations Unveils New SCALE-iFlex LT NTC IGBT/
SiC Module Gate Drivers with Temperature Readout SCALE-2 technology improves current sharing by 20 percent for the popular new dual style of 100 mm x 140 mm IGBT and SiC power modules
MIKROE’s IrDA 4 Click provides a cost-effective
solution for sending and receiving IR serial data Latest wireless connectivity Click features Vishay IR Tx and Microchip IR encoder/decoder
Power Integrations (NASDAQ: POWI), the leader in gate-driver technology for medium- and high-voltage inverter applications, today introduced the SCALE-iFlex™ LT NTC family of IGBT/SiC module gate drivers. The new gate drivers target the popular new dual, 100 mm x 140 mm style of IGBT modules, such as the Mitsubishi LV100 and the Infineon XHP 2, as well as silicon carbide (SiC) variants thereof up to 2300 V blocking voltage. The SCALE-iFlex LT NTC drivers provide Negative Temperature Coefficient (NTC) data – an isolated temperature measurement of the power module – which enables accurate thermal management of converter systems. This is particularly important for systems with multiple modules arrayed in parallel, ensuring proper current sharing and dramatically enhancing overall system reliability. Thorsten Schmidt, product marketing manager at Power Integrations commented: “Designers of renewable energy and rail systems using SCALE- iFlex drivers already benefit from increased system performance; the SCALE-iFlex approach handles paralleling so expertly that one module in five can be eliminated without loss of performance or current de-rating. Adding an isolated NTC output reduces hardware complexity – particularly cables and connectors – and contributes to system observability and overall performance.” Based on Power Integrations’ proven SCALE™-2 technology, SCALE-iFlex LT gate drivers improve current sharing accuracy and therefore increase the current carrying capability of multiple-paralleled modules by 20 percent, allowing users to significantly increase the semiconductor utilization of their converter stacks.

One-piece 2nd generation GDBC connectors from Gigalane for complex stack ups in 5G systems now available from Powell Electronics
MikroElektronika (MIKROE), the embedded solutions company that dramatically cuts development time by providing innovative hardware and software products based on proven standards, has expanded its range of wireless connectivity Click™ boards with the IrDA 4 Click, a compact add-on board that provides a cost-effective solution for sending and receiving IR serial data. This board features the TFBS4650, an infrared transceiver from Vishay Semiconductors, which includes a PIN photodiode, an infrared emitter, and a low-power integral circuit and complies with the IrDA physical layer specification. IrDA 4 Click also includes an infrared encoder/decoder, the MCP2120 from Microchip, that sends and receives IR serial data between the infrared transceiver module and the host MCU. Click boards follow a modular prototyping add-on board standard invented by MIKROE, which revolutionizes the way users add new functionalities to development boards. Click boards™ enable design engineers to change peripherals easily, cutting months off development time. The mikroBUS™ socket standard enables any Click board to be instantly connected to the microcontroller or microprocessor on a main board. Many leading microcontroller companies including Microchip, NXP, Infineon, Dialog, STM, Analog Devices, Renesas and Toshiba now include the mikroBUS socket on their development boards. Comments Nebojsa Matic, CEO of MIKROE: “This Click board makes the perfect solution for the development of short-distance communication and data transfer or in use in environments where RF is problematic.” IrDA 4 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

Precision and versatility in one cordless drill & driver for professional use
Panasonic presents the new EY1DD2 cordless drill & driver for a wide range of applications
With the EY1DD2, Panasonic Power Tools Europe introduces a versatile cordless drill & driver for demanding operations.
The short body measures only 133mm and with a 5.0Ah battery pack weighs just 1.75kg. But the powertool this light and compact does not lack functionality:
With optional accessories like the ¼ inch Hex Eccentric attachment, that can be mounted in eight positions, precision drilling even in tight corners is made very easy.
Furthermore, a ¼ inch right-angle attachment is available, also connectable to the tools body in eight different positions, to work in tight angle environments. A simple push of bits or drills into the tool is enough to mount them into place. The need to fix the inserts by pulling the quick chuck sleeve is obsolete. And with the keyless drill chuck attachment, straight shank drill bit from 1.5 – 13mm in diameter can also be mounted.
Preset Modes for drilling, driving and tapping - The preset modes of the EY1DD2 allow for a easy and quick
Now in stock at Powell Electronics, the supplier of connectors and more for high-rel applications including defence, aerospace and industrial, are 2nd generation one-piece GDBC direct board contacts from Gigalane. The simple one-piece design of the components enables a high integration and miniaturization of board-to-board and board-to-module RF interconnections. GDBC series contacts are very easy to use in the assembly as they require no SMT. They offer the lowest total- cost-of-ownership on the market and are an ideal solution for multiple connections and complex stack ups in 5G systems.
Technical details of 2nd generation GDBC contacts include a frequency from DC up to 8.5 GHz, impedance of 50 Ω, insulation resistance of 5000 MΩ and a dielectric withstand voltage of 750 Vrms. VSWR is 1.12:1 at 3.0 GHz, 1.22:1 at 6.0 GHz and 1.35:1 at 8.5 GHz.

adaptation of the power and speed output: “You can choose with just a push of the mode button, how much torque is available for wood or fine metal drilling”, says Kunihiko Nedachi, Head of Power Tools Europe. “Depending on the setting, up to 45Nm of torque are available, and thanks to the new brushless motor and vector control circuit, power and speed are optimized for demanding applications like e.g., heavy-duty serial drilling”.
Also the newly developed electronic clutch enables the drill & driver to provide ideal shut-off clutch torque for precise high-torque fastening. A green LED light indicates when the pre-set shut-off clutch torque has been reached, indicating the desired tightness of the bolt.
Alongside the optional accessories, every cordless drill & driver EY1DD2 comes with a storage space for two 65mm bits in its base, furthermore a belthook and the soft grip texture improve the handling of this versatile power tool.
