Easy to configure MEDIMOD 120W medical switcher from UNIPOWER
UNIPOWER LLC has unveiled a key new addition to its MEDIMOD range of medically approved power platforms. The MEDIMOD AM-120UM is a 120W switch mode power supply with single to quad output voltages that can be quickly configured to suit customers’ exact requirements. The platform comes with a universal AC input that meets EN61000-3-2, MEDIMOD AM- 120UM power supplies are available in a comprehensive range of single to quad output configurations from 1.5 to 48VDC and deliver 120W of highly regulated output power. The AM-120UM meets EN 60101, features Class B emissions, is CE marked and will operate up to 70ºC delivering continuous full power up to 50ºC. Housed in a U-frame package measuring 127 x 83.08 x 38.1mm (3.3 x 5in x 1U), MEDIMOD units boast an MTBF greater than 250k hours at 25 ºC according to MIL-217F. As well as providing customers with a choice of output voltages and output combinations, UNIPOWER can also supply MEDIMOD power supplies with a wide variety of options which are available without any impact on safety approvals. These include covers with or without fans, extended temperature range, -40ºC guaranteed start-up, 12, 24 and 48VDC inputs, isolated outputs, remote sense and overtemp protection.
UNIPOWER can also provide these units with ITE safety approvals.
The MEDIMOD and EASYMOD power platforms are designed to offer users a power supply that exactly meets the needs of their application. Starting with an industry standard footprint, units can be quickly configured to provide the right output combinations and user defined features not available with standard power supplies.

New driver IC for high-efficiency LED lighting applications
www.element14.com www.farnell.co.uk
Renesas Electronics have launched a new driver IC, the R2A20135SP. The latest member of Renesas' driver IC family is designed for high- accuracy, high-efficiency LED lighting systems, and features an on-chip dimming function and a 40-percent size decrease for the mounting area, making it a suitable solution for LED lighting fixture manufacturers. Renesas will also provide an evaluation board with the new driver IC installed on it to provide development support for system designers. Renesas also offers a lineup of high-performance power MOSFETs for use with driver ICs for LED lighting systems as well as kit solutions featuring both types of devices.
LED lighting systems combining low power consumption, high efficiency and long service life have gained considerable attention in recent years amid worldwide efforts to save power and reduce emissions of carbon dioxide. LEDs have come into widespread use in industrial and commercial equipment, as well as in lighting
fixtures for outdoor and household use. The market for such products is expected to continue to grow substantially.

Overvoltage protectors user reverse bias blocking to protect portable device with multiple power sources
Maxim Integrated Products has announced the MAX14606/MAX14607, an advanced overvoltage protector which handles up to 3A of continuous current for high-power electronics. Reverse bias blocking protects a portable device from damage caused by multiple power sources supplied simultaneously. The
MAX14606/MAX14607 have been optimised to protect the internal components of portable electronics such as tablets, smartphones, and portable media players.
The MAX14606/MAX14607 feature reverse bias blocking capability so that two power sources can be safely interfaced simultaneously without damage to either one. In this design two integrated back-to-back FETs prevent the voltage applied at the intended output from feeding back into the input. Without this reverse bias blocking, users are forced to use multiple discrete, space-consuming external components to protect the end equipment.

In order to meet the demands of high-power portable devices, the MAX14606/MAX14607 also use low, 54m (typical) on-resistance (RON), integrated FETs that allow up to 3A of continuous current and protect low-voltage systems against voltage faults up to +36V. “The electronics industry must constantly adapt to the changing needs and lifestyles of consumers, so system designers need better building blocks,” said Sidney Chan, Business Manager for Maxim. “Now the integrated, back- to-back FETs and the low RON in the MAX14606/MAX14607 will let users conveniently charge a portable electronic through USB and/or a wireless charging dock, for example, without worrying about damaging their device.”
