Networking

Based on the Analog Devices, Inc., isoPower technology, the

on-chip isolated dc-to-dc converter provides a regulated, isolated

voltage of 3.15 V to 5.25 V with up to 150 mW of output power

(see Figure 1).

GENERAL DESCRIPTION

Based on the iCoupler® and isoPower® chip scale transformer

technology, the ADM3260¹is a hot swappable digital and power

isolator with two nonlatching, bidirectional communication

channels, supporting a complete isolated I²C interface, and an

integrated isolated dc-to-dc converter, supporting up to

150 mW of isolated power conversion.

With the ADM3260, the iCoupler and isoPower channels, along

with the I²C transceivers, can be integrated with semiconductor

circuitry, which enables a complete isolated I²C interface and

allows the power converter to be implemented in a small form

factor. The ADM3260 is available in 20-lead SSOP package and

has an operating temperature range of −40°C to+105°C.

iCoupler is a chip scale transformer technology with functional,

performance, size, and power consumption advantages as

compared to optocouplers. The bidirectional I²C channels

eliminate the need for splitting I²C signals into separate transmit

and receive signals for use with standalone optocouplers.

isoPower uses high frequency switching elements to transfer power

through its transformer. Special care must be taken during printed

circuit board (PCB) layout to meet emissions standards. See the

AN-0971 Application Note for board layout recommendations.
