ADUM5000ARWZ-R 概述
An isolated DC/DC converter is a power-management device that transfers energy across a galvanic isolation barrier while maintaining regulatory compliance for high-voltage safety standards. In the broader system hierarchy it sits below discrete transformer-based designs and above simple non-isolated buck regulators, allowing designers to remove bulky transformers, optocouplers, and feedback components from industrial, medical, and instrumentation power trees.
Key features include 2.5 kV rms isolation (UL 1577 / IEC 60747-5-2 qualified), >25 kV/us common-mode transient immunity, integrated thermal shutdown, and a high-temperature operating range up to 105 C. The ADUM5000ARWZ-R replaces legacy transformer-isolated supplies with a single SOIC that delivers up to 33% power-transfer efficiency at full load, dramatically shrinking PCB area for isolated 5 V or 3.3 V rails.
Internally, the device uses Analog Devices' isoPower architecture, combining a PWM-driven primary side, an on-chip air-core transformer, and a secondary-side linear post-regulator. The post-regulator removes ripple from the secondary rectified waveform, eliminating the need for external LC filters while keeping output noise low enough for analog front-end and RS-485 transceiver bias rails.
Typical applications include isolated RS-485/RS-232 transceivers, industrial field-bus nodes (Modbus, PROFIBUS, CAN isolated), 4 mA to 20 mA loop-powered transmitters, medical patient-monitoring front ends, and PLC digital-input modules that must survive fast common-mode swings on long cable runs.
When designing with the ADUM5000ARWZ-R, observe the >8 mm creepage/clearance budget provided by the wide SOIC footprint and place a 0.1 uF decoupling capacitor on each VDD pin within 2 mm of the package to keep the primary-side switching noise from coupling back into the upstream supply.

典型应用
ADUM5000ARWZ-R 适用于 6 应用s: Isolated RS-485 / RS-232 Transceiver Bias, Industrial Field-Bus Nodes (Modbus, PROFIBUS, CAN-isolated), 4-20 mA Loop-Powered Transmitters, Medical Patient-Monitoring Auxiliary Power, PLC Digital-Input Module Isolated Bias, Isolated Sensor Front-End for Data Acquisition.
Isolated RS-485 / RS-232 Transceiver Bias
The ADUM5000ARWZ-R provides the isolated 3.3 V or 5 V supply that powers the bus-side of RS-485/RS-232 links in industrial nodes. Its 2.5 kV rms isolation per UL 1577 satisfies reinforced insulation between the field-bus cable (which can carry ground-potential differences of hundreds of volts) and the local MCU. The 500 mW output budget comfortably drives multiple transceiver channels plus termination bias resistors, while the >25 kV/us CMTI prevents common-mode transients from large motor VFDs from corrupting data passing through companion iCoupler digital channels.
推荐
Industrial Field-Bus Nodes (Modbus, PROFIBUS, CAN-isolated)
Programmable logic controllers and distributed I/O modules place isolated field-bus nodes on the factory floor, where ground-potential differences and EMI from VFDs and motor starters easily exceed 1 kV. The ADUM5000ARWZ-R's 2.5 kV rms isolation and >25 kV/us CMTI make it well-matched to Modbus RTU, PROFIBUS DP, and isolated CAN physical layers. With 100 mA output current at 5 V it directly powers isolated transceiver ICs plus small signal-conditioning front ends, replacing bulky discrete transformer-based supplies with a single SOIC-W footprint.
推荐
4-20 mA Loop-Powered Transmitters
Two-wire 4-20 mA loop-powered smart transmitters in process control must operate from as little as 12 V loop voltage while delivering isolated power to their sensor-side AFE. The ADUM5000ARWZ-R's small SOIC-W package fits inside the constrained transmitter head, and its wide 2.7 V to 5.5 V input is derived after a high-efficiency buck pre-regulator drops the loop voltage. The 2.5 kV rms isolation barrier protects the loop-powered side from sensor faults and field wiring transients, while the integrated thermal shutdown prevents damage during sensor short-circuit conditions.
推荐
Medical Patient-Monitoring Auxiliary Power
Patient-monitoring peripherals such as SpO2, ECG, and temperature modules require reinforced isolation between the patient-connected side and the host instrument. The ADUM5000ARWZ-R's 2.5 kV rms rating per UL 1577 supports 1 MOPP (one means of patient protection) isolation for auxiliary bias rails that power sensor AFE and LED drivers. Combined with an ADuM141E digital isolator for data paths, it builds a compact patient-isolated power tree. For 2 MOPP designs, designers step up to ADuM5400/ADuM6000 family parts, but the ADUM5000ARWZ-R remains optimal for non-life-support peripherals.
推荐
PLC Digital-Input Module Isolated Bias
PLC digital-input modules interface 24 V field wiring to the backplane logic and need isolated 5 V or 3.3 V rails for input-side conditioning circuits. The ADUM5000ARWZ-R's wide 2.7 V to 5.5 V input lets it run directly off the 24 V PLC bus through a small buck pre-regulator, while delivering isolated power to opto-coupler or digital-isolator input-side circuits. The >25 kV/us CMTI protects the isolated rail from the high dv/dt switching transients of nearby relay and solenoid outputs, ensuring robust operation in electrically noisy cabinet environments.
推荐
Isolated Sensor Front-End for Data Acquisition
Multi-channel data-acquisition systems digitizing high-side or bus-connected sensors need isolated bias rails for their analog front-end to break ground loops. The ADUM5000ARWZ-R provides 500 mW of clean 5 V power to isolated ADCs, op-amps, and reference buffers, while iCoupler data isolators carry the SPI/LVDS conversion. With 2.5 kV rms isolation it tolerates large CMV transients on the sensor bus, and the small SOIC-W footprint keeps channel density high in 16+ channel simultaneous-sampling DAQ boards.

设计说明
Place 0.1uF decoupling capacitors on both VDD1 (primary) and VDD2 (secondary) within 2 mm of the package pins to suppress primary-side switching noise. The ADuM5000 datasheet recommends a thermal-via array under the exposed pad to the internal ground plane; this both reduces theta_JA and provides shielding for the on-chip transformer. Maintain >8 mm clearance under the package body to satisfy the SOIC-W wide-body creepage requirement.
At full 500 mW output with 33% efficiency, the ADUM5000ARWZ-R dissipates approximately 1 W as heat. With the 16-lead SOIC-W thermal pad, theta_JA on a 4-layer JEDEC test board is approximately 80 C/W, giving an 80 C junction temperature rise at full load. For continuous 500 mW operation in enclosed industrial enclosures, provide at least 1 square inch of inner-layer copper connected to the exposed pad.
Do not load the ADUM5000ARWZ-R secondary output with high di/dt switching transients (e.g., directly into a buck regulator input) without adequate bulk capacitance - the integrated post-regulator has limited loop bandwidth and may exhibit output ripple under abrupt load steps. According to the ADuM5000 datasheet, place at least 10 uF X7R ceramic plus 1 uF X7R on VDD2 to handle step loads up to 50 mA. Also verify VSEL pin logic level matches the desired output voltage (referenced in datasheet Table 1) before power-up; floating VSEL defaults to 5 V in some assembly variants.
