ADUM5010ARSZ-RL7 Übersicht
An isolated dc-to-dc converter is a power management IC that transfers power across a galvanic isolation barrier while maintaining regulated output voltage. Unlike optocoupler-plus-transformer discrete solutions, transformer-based iCoupler devices integrate the isolation barrier, power transformer and regulation on a single chip, sitting within the hierarchy: isolated dc-to-dc converter -> switching voltage regulator -> power management IC -> semiconductor.
Key features include 2.5 kV rms isolation rating, adjustable isolated output setpoint (VISO nominally 3.3 V with R1 = 10 kOhm, R2 = 16.9 kOhm per the datasheet), input operation from slightly below to significantly above the required output voltage, and a low thermal coefficient of approximately -26 uV per degree C on the output setpoint. The iCoupler chip-scale transformers provide both the isolated logic channel and the magnetic components of the power converter, eliminating external magnetics.
Architecturally, the device resonantly drives an on-chip air-core transformer to move power across the barrier, then regulates the secondary side; the data sheet addresses three discrete operating conditions covering input/output voltage combinations supported at room temperature (Figure 13 of the ADuM5010 datasheet depicts the supported map).
Typical applications include isolated RS-485/RS-232 transceiver supplies, isolated industrial PLC I/O channels, isolated CAN/isolated sensor interfaces, and medical isolation front ends where a small form factor total isolation solution is required.
Design consideration: verify your input/output voltage combination is inside the supported combinations map and budget load current within the 30 mA limit; the output setpoint is adjusted with two external resistors, so use 1% or better tolerance parts to preserve accuracy.

Typische Anwendungen
ADUM5010ARSZ-RL7 ist geeignet für 6 Anwendungs: Isolated RS-485 Industrial Communication Nodes, Isolated CAN Bus Interfaces, Isolated Sensor Front Ends in PLC I/O, Medical Isolation Front Ends, Isolated Gate Driver Supplies, Isolated RS-232 and UART Links.
Isolated RS-485 Industrial Communication Nodes
The ADUM5010ARSZ-RL7 fits isolated RS-485 nodes because industrial fieldbus installations routinely face hundreds of volts of ground-potential difference between nodes, requiring a galvanically isolated transceiver supply. Its 2.5 kV iCoupler isolation barrier and regulated 3.15 V to 5.25 V output at up to 30 mA comfortably power the isolated side of low-power RS-485 transceivers. Placed as the sole supply for the isolated transceiver side with 0.1 uF and 10 uF local decoupling, it eliminates optocoupler feedback loops and discrete magnetics entirely. The performance consideration is load budgeting: the 30 mA ceiling must cover transceiver idle plus drive current, so verify against the datasheet supported input/output combination map at room and elevated temperatures.
Empfohlen
Isolated CAN Bus Interfaces
CAN networks in automotive, factory automation, and building control commonly need an isolated physical layer to block ground loops and common-mode transients. The ADUM5010ARSZ-RL7 supplies the isolated rail for CAN transceivers: its 3.3 V nominal setpoint (R1 = 10 kOhm, R2 = 16.9 kOhm) and 30 mA capability match the supply demands of 3.3 V or 5 V CAN transceivers in typical 1 Mbps networks. Because iCoupler chip-scale transformers handle both the power transfer and the isolation, the design needs no external transformer, cutting board area versus discrete flyback or push-pull solutions. The key trade-off is that heavy bus loading scenarios must stay under 30 mA; measure worst-case transceiver supply current across dominant-recessive duty cycles before finalizing the design.
Empfohlen
Isolated Sensor Front Ends in PLC I/O
Programmable logic controller I/O channels often float at field potentials and need both signal isolation and a small isolated power supply for the sensor-side circuitry. The ADUM5010ARSZ-RL7's total isolation solution - integrated power and signal transformers on one die - makes it a compact choice for powering isolated conditioning circuits such as op-amps, ADCs, and reference ICs drawing a few milliamperes each. Its -26 uV per degree C setpoint drift keeps the isolated rail stable over the industrial temperature span, protecting measurement accuracy. Designers should combine it with an isolated signal channel (for example an ADuM120x digital isolator) and budget the aggregate secondary-side load within the 30 mA envelope, using the datasheet Figure 13 voltage-combination map to confirm the chosen VIN/VOUT pair is supported.
Empfohlen
Medical Isolation Front Ends
Patient-connected measurement equipment requires a galvanic barrier protecting the patient from mains-referenced electronics. The ADUM5010ARSZ-RL7 provides 2.5 kV isolation in a small 20-lead SSOP footprint, suitable for powering low-power analog front ends in monitoring devices where only a few tens of milliamperes of isolated current are needed. Because the iCoupler architecture avoids optocoupler LED aging and CTR degradation, the isolated power transfer remains stable over device lifetime, an important consideration for long-service medical instruments. The trade-off versus a 5 kV family member (ADuM6000/ADuM6010) is the lower isolation rating; designs targeting reinforced-patient-applied-part standards should evaluate the 5 kV variants, while the ADuM5010 suits functional-isolation blocks and auxiliary isolated supplies.
Empfohlen
Isolated Gate Driver Supplies
Low-power isolated gate-drive stages for small MOSFETs and IGBTs, or for auxiliary bias of gate-driver ICs, need a compact floating supply referenced to a switching potential. The ADUM5010ARSZ-RL7 generates that floating rail directly from the logic-side 3 V to 5.5 V input across its 2.5 kV barrier, adjustable 3.15 V to 5.25 V to match gate-drive requirements. At up to 30 mA it supports bias supply duties rather than direct high-frequency gate charging, so pair it with a driver IC whose quiescent plus average gate-drive current stays within budget. The small form factor, total isolation solution shines in multichannel converters where several floating rails are needed and discrete bias transformers would dominate the layout area.
Empfohlen
Isolated RS-232 and UART Links
Legacy RS-232 links in industrial equipment, test fixtures, and service ports still require isolation when connecting to machines with unknown ground references. The ADUM5010ARSZ-RL7 powers the isolated side of an RS-232 transceiver: its 30 mA output covers typical single- and dual-driver RS-232 transceiver supply requirements, and the adjustable setpoint supports both 3.3 V and 5 V transceiver families. Using iCoupler chip-scale transformers for the power transfer removes the optocoupler-plus-DC/DC-module combination traditionally used, shrinking the isolation section to a single 20-lead SSOP device plus two external setpoint resistors and decoupling capacitors. Confirm the transceiver's worst-case current, including any charge-pump overhead, remains below the 30 mA limit across supply corners.

Wichtigste Unterscheidungsmerkmale
- Adjustable isolated output for rail matching (vs. ADuM5000ARSZ)
- Lower cost for standard isolation requirements (vs. ADuM6010ARSZ)
- Tape and reel for automated assembly (vs. ADuM5010ARSZ)
Designhinweise
Budget the secondary-side load strictly within the 30 mA output capability. Sum the quiescent current of every device on the isolated rail (transceiver, ADC, isolators) plus peak transient demands; exceeding the limit collapses the isolated rail and can interrupt communication. The isolated setpoint is defined with IISO = 15 mA in the datasheet specifications (3.3 V with R1 = 10 kOhm, R2 = 16.9 kOhm), so verify regulation at your actual load point. Confirm your VIN/VOUT pair appears in the supported combinations map (Figure 13 of the ADuM5010 datasheet), which covers three discrete operating conditions at room temperature.
Place 0.1 uF ceramic decoupling capacitors directly at both the primary-side VIN pin and the secondary-side VISO pin, with an additional 10 uF bulk capacitor per side to handle the switching current pulses drawn by the iCoupler power transformer. Route the isolation gap between primary and secondary pins per your safety standard's creepage and clearance requirements; do not run traces under the package across the barrier. Keep the external setpoint resistors R1 and R2 close to the feedback pin and use 1% tolerance or better, since divider error maps directly into isolated-rail error.
The -RL7 suffix is a packaging variant only - do not confuse ADuM5010ARSZ (tube) with a different electrical grade; they are identical silicon. Do not assume the isolated output is fixed: it is set by external resistors, and an incorrect R1/R2 ratio produces the wrong isolated voltage. Finally, remember the setpoint thermal coefficient of approximately -26 uV per degree C when specifying rail accuracy over temperature, and never exceed the 5.5 V absolute input range when powering from logic rails with transients.
