can operate with a power supply as low as 2.2V. The two devices are the “TLP2312,” which delivers at typical data transfer rate of 5Mbps, and the 20Mbps “TLP2372.” Shipments start today. The new products are designed to operate at low voltage, starting at 2.2V, so as to work with the lower voltages of the peripheral circuits, even when used in such low level voltage circuits as 2.5V LVCMOS. This approach eliminates the need for a separate power supply to drive the photocouplers, reducing the component count. With a low threshold input current of 1.6mA (max), and low supply current of 0.5mA (max) in their -40℃ and +125℃ operating temperature range, the new photocouplers can be directly driven bymicrocontrollers, reducing power consumption. The new photocouplers are housed in 5-pin SO6 package with a maximum height of 2.3mm, securing a low profile and bringing greater freedom to component layout on printed circuit boards.

Switch Mode Power Supply by Mascot Produces Up To 120W Output 3820 power supply with medical certification provides excellent quality-to-price ratio The latest addition to the class-leading Mascot Blueline series of power supplies is the switch mode 3820 external PSU. Designed to meet global power conversion requirements, the 3820 is medically certified in accordance with EN 60601-1 edition 3.1 (safety) and EN 60601-1-2 edition 4 (EMC). Working with universal AC line voltages from 90V to 264V, the high-efficiency 3820 offers continuous output power up to 120W. Applications for the new power supply include medical devices such as CT and PET scanners, incubators, blood analysers, DNA equipment, ultrasound systems, diagnostics units and medication dispensers, to list but a few. Further uses include communications systems and security devices, for example. Mascot’s 3820 power supply provides product designers with a turnkey solution that is built on a number of key criteria. Notably, these measures include high quality, competitive price and compliance with the latest eco- design specifications (CoC Tier 2, DoE level VI, CEC, MEPS) adopted in the EU and North America. In addition, the high-performance, CE-marked 3820 PSU has worldwide UL Certification. Four standard versions are available offering fixed output voltages of 12, 24, 36 and 48V. Other versions and custom designed units with special plugs and cords are available on request. All units have short-circuit protection Input terminals are IEC 60320 2-pin C8 or 3-pin C14 connector, while output terminals are served by a cord with or without a plug. Exchangeable DC plugs can also be offered. Plugs, a selection of mains cordsets and an optional mounting bracket are available to order separately. Key technical specifications of the 3820: * Universal input voltage, max output power 120W * UL approved and medically certified for safety and EMC * 4 versions: 12, 24, 36, 48V * Weight 530g * Dimensions: 172.5mm x 73mm x 42mm
