Power management converter transformers for Analog Devices transceiver chips introduced by Murata Power
Posted by John Keller
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.
