The ADuM3123 is a 4.0 A isolated, single channel driver that employs Analog Devices, Inc.’siCoupler®technology to provide precision isolation. The ADuM3123 provides 3000 VRMSisolation in the narrow body 8-lead SOIC package. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and gate drivers.The ADuM3123 operate with an input supply ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems. In comparison to gate drivers employing high voltage level translation methodologies, the ADuM3123 offer the benefit of true, galvanic isolation between the input and the output. The output may be continuously operated up to 380 V rms relative to the input.As a result, the ADuM3123 provide reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.ApplicationsSwitching power suppliesIsolated IGBT/MOSFET gate drivesIndustrial inverters

The ADuM3160 is aUSBport isolator, based on Analog Devices, Inc.,iCoupler®technology. Combining high speed CMOS and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics and is easily integrated with low and full speed USB-compatible peripheral devices.Many microcontrollers implement USB so that it presents only the D+ and D− lines to external pins. This is desirable in many cases because it minimizes external components and simplifies the design; however, this presents particular challenges when isolation is required. Because the USB lines must switch between actively driving D+/D− and allowing external resistors to set the state of the bus, the ADuM3160 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers. Data direction is determined on a packet-by-packet basis.The ADuM3160 uses the edge detection basediCoupler technology in conjunction with internal logic to implement a transparent, easily configured, upstream-facing port isolator. Isolating the upstream port provides several advantages in simplicity, power management, and robust operation.The isolator has propagation delay comparable to that of a standard hub and cable. It operates with the supply voltage on either side ranging from 3.0 V to 5.5 V, allowing connection directly to VBUSxby internally regulating the voltage to the signaling level. The ADuM3160 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing. The device draws low enough idle current that a suspend state is not required. A 5 kV, reinforced insulation version, the ADuM4160, is available.APPLICATIONSUSB peripheral isolationIsolated USB hub

The ADuM3190 is an isolated error amplifier based on Analog Devices, Inc.,iCoupler®technology. The ADuM3190 is ideal for linear feedback power supplies. The primary side controllers of the ADuM3190 enable improvements in transient response, power density, and stability as compared to commonly used optocoupler and shunt regulator solutions.Unlike optocoupler-based solutions, which have an uncertain current transfer ratio over lifetime and at high temperatures, the ADuM3190 transfer function does not change over its lifetime, and it is stable over a wide temperature range of −40°C to +125°C.Included in the ADuM3190 is a wideband operational amplifier for a variety of commonly used power supply loop compensation techniques. The ADuM3190 is fast enough to allow a feedback loop to react to fast transient conditions and overcurrent conditions. Also included is a high accuracy 1.225 V reference to compare with the supply output setpoint.The ADuM3190 is packaged in a small 16-lead QSOP package for a 2.5 kV rms isolation voltage rating.ApplicationsLinear power suppliesInvertersUninterruptible Power Supply (UPS)DOSA-compatible modulesVoltage monitorsAutomotive systems
