MANSFIELD, Mass., 12 Nov. 2009. Murata Power Solutions Inc. in Mansfield, Mass., is introducing a series of converter transformers for use in power management with the Analog Devices ADM2482/7 transceiver chipsets for isolated RS-485 and RS-422 interfaces.

The Murata 782482 series power electronics devices has controlled turns ratios to ensure consistent performance while a toroidal construction helps minimize electromagnetic interference (EMI).

Housed in an industry-standard, dual-inline package using UL94 V-0 materials, the 782482 measures 0.339 by 0.360 by 0.25 inches. Nominal input voltages are 3.3 volts for the 782482/33VC and 5 volts for the 782482/53VC; both models have a nominal output voltage of 3.3 volts and provide 4 kilovolts DC isolation.

The series has an industrial temperature range of -40 to 85 degrees Celsius. Both models are RoHS compliant and backward compatible with tin-lead soldering systems. Surface mount versions of the converter transformers are under development.

The Analog Devices ADM2482/7 are isolated data transceivers with plus-or-minus 15 kilovolt ESD protection and are suitable for high speed, half-duplex, or full-duplex communication on multipoint transmission lines.

The devices employ the Analog Devices iCoupler technology to combine a three-channel isolator, a three-state differential line driver, and a differential input receiver into one package. For more information contact Murata Power online at www.murata-ps.com.
