It serves as bias supply for isolated RS-485/RS-422/CAN transceivers in industrial and automotive systems.
For engineers reviewing the ADuM6028-5WBRIZ-RL datasheet, ADuM6028-5WBRIZ-RL pinout, ADuM6028-5WBRIZ-RL application, or ADuM6028-5WBRIZ-RL equivalent, this page delivers verified specifications, safety-certified isolation parameters, thermal derating behavior, regulatory compliance details (UL 1577, VDE 0884-17, IEC 62368-1), and real-world use context for power sequencing in isolated communication interfaces.
Technical Context
The ADuM6028-5WBRIZ-RL uses chip-scale magnetic transformers for galvanic isolation and employs pulse-width modulation (625 kHz) with high-frequency switching (180 MHz) to regulate its 5 V isolated output. Its internal architecture integrates primary-side control, secondary-side feedback via isolation barrier, and undervoltage lockout (VDDP rising threshold: 3.6–4.4 V).
It is rated for reinforced insulation (VIORM = 565 V peak, VISO = 5000 V rms, 1 min), operates from −40°C to +125°C, and features thermal shutdown at 154°C with 10°C hysteresis. The device is AEC-Q100 qualified and supports automotive on-board charger (OBC) auxiliary power and PLC sensor interface isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Input Voltage Range | 4.5 V to 5.5 V - compatible with standard 5 V rail systems and tolerant of ±10% supply variation. |
| Output Ripple | 75 mV p-p (20 MHz BW, 0.1 µF||10 µF bypass) - low enough for noise-sensitive analog front-ends when combined with local LDO post-regulation. |
| Switching Frequency | 625 kHz PWM / 180 MHz oscillator - enables compact external filtering and minimizes conducted EMI in space-constrained designs. |
| Thermal Resistance | θJA = 80 °C/W - requires careful thermal layout on 2-layer boards; derates output current by 1 mA/°C above 85°C ambient. |
| Regulatory Approvals | UL 1577, VDE 0884-17, IEC 62368-1, IEC 60601-1, CQC GB4943.1 - certified for safety-critical end equipment including OBCs and PLCs. |
Pinout & Package
ADuM6028-5WBRIZ-RL is housed in an 8-lead wide-body SOIC_IC package (SOIC_W) with 8.3 mm minimum creepage and clearance between input and output sides. Pins 1–4 form the primary side (GND1, PDIS, VDDP); pins 5–8 form the secondary side (GNDISO, VISO). No internal connection (NIC) pins are absent - all 8 pins are functional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | GND1 | Primary-side ground reference; must be connected to system input ground plane with low-inductance path. |
| Pin 2 | PDIS | Power disable control: logic high disables VISO output; tie to GND1 to enable - critical for power sequencing in multi-rail systems. |
| Pin 3 | VDDP | Primary supply input (4.5–5.5 V); supplies internal oscillator, control logic, and transformer driver. |
| Pin 4 | GND1 | Secondary primary ground pin; electrically tied to Pin 1 - use both for low-impedance grounding. |
| Pin 5 | GNDISO | Isolated secondary ground; forms return path for VISO load current - must be separated from GND1 by ≥8.3 mm. |
| Pin 6 | VISO | Regulated 5 V isolated output (4.75–5.25 V); powers downstream isolated circuitry such as transceiver VCC or ADC reference. |
| Pin 7 | GNDISO | Secondary ground pin; electrically tied to Pin 5 - use both for low-noise return path on isolated side. |
| Pin 8 | GNDISO | Third GNDISO terminal; improves thermal dissipation and reduces ground bounce on high-current transient loads. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated isoPower® DC/DC | Eliminates discrete transformer, controller, and feedback optocoupler - reduces BOM count and layout area by >50% vs. discrete isolated supply. |
| CISPR22 Class B compliant | Meets radiated/conducted emission limits on 2-layer PCB without ferrite beads or shielding - simplifies EMC validation for industrial gateways. |
| AEC-Q100 qualified | Validated for automotive temperature cycling, humidity, and vibration - suitable for OBC auxiliary power and battery management system isolation. |
| Reinforced insulation (VDE 0884-17) | VIORM = 565 V peak, VIOSM = 10,000 V peak surge - supports 2 MOPP medical isolation and 400 Vrms working voltage in EV charging infrastructure. |
| Thermal shutdown with hysteresis | Shuts down at 154°C and re-enables at 144°C - prevents latch-up during overload or poor heatsinking in enclosed enclosures. |
Applications
| Industrial PLC I/O Modules | Automotive On-Board Charger (OBC) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated dc-to-dc converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADuM6028-5BRIZ | Same die, same 8-lead SOIC_IC package, identical electrical specs - differs only in tape-and-reel packaging (no -RL suffix) and absence of W-grade marking. | No functional difference; used in non-automotive or non-extended-temp applications where AEC-Q100 qualification is not required. | Select ADuM6028-5WBRIZ-RL when AEC-Q100 Grade 1 (−40°C to +125°C) and automotive traceability are mandatory. |
| ADM3053BRWZ | Integrated isolated CAN transceiver + 5 V isoDC/DC (60 mA); larger 20-lead SOIC package; higher quiescent current (IDDP(Q) = 35 mA vs. 8–25 mA). | Combines signal and power isolation in one device - ideal for CAN node-level integration but lacks flexibility for RS-485 or general-purpose isolated bias. | Choose ADM3053BRWZ only when CAN physical layer integration is needed; ADuM6028-5WBRIZ-RL offers superior efficiency and smaller footprint for generic isolated supply roles. |
Compared with ADuM6028-5BRIZ, the -5WBRIZ-RL adds AEC-Q100 qualification and extended thermal validation; compared with ADM3053BRWZ, it provides dedicated, lower-noise isolated power without fixed protocol constraints - making it more flexible for multi-protocol industrial gateways and medical sensor hubs.

FAQ
What is the maximum continuous output current of the ADuM6028-5WBRIZ-RL at 125°C ambient?
The ADuM6028-5WBRIZ-RL delivers up to 60 mA at 25°C, but output current is derated linearly by 1 mA/°C above 85°C ambient. At 125°C, maximum continuous output current is 20 mA (60 mA − 40 × 1 mA). This derating ensures safe operation within thermal limits defined by θJA = 80 °C/W and junction temperature < 154°C.
Does the ADuM6028-5WBRIZ-RL support 3.3 V input operation?
No - the ADuM6028-5WBRIZ-RL is configured for 5 V primary input (VDDP = 4.5–5.5 V) and 5 V isolated output (VISO = 4.75–5.25 V). For 3.3 V input operation, use ADuM6028-3WBRIZ-RL (3.0–3.6 V input, 3.3 V output), which shares the same package, safety ratings, and AEC-Q100 qualification.
How does the PDIS pin function in the ADuM6028-5WBRIZ-RL?
The PDIS (Power Disable) pin on the ADuM6028-5WBRIZ-RL controls VISO output enable/disable: tying PDIS to GND1 enables the isolated supply; applying logic high (>2.0 V) disables VISO. It must never be left floating. This feature allows precise power sequencing - for example, delaying isolated rail activation until primary logic is stable.
What safety certifications apply specifically to the ADuM6028-5WBRIZ-RL variant?
The ADuM6028-5WBRIZ-RL carries UL 1577 (5000 V rms, 1 min), VDE 0884-17 (VIORM = 565 V peak), IEC 62368-1, IEC 60601-1 (2 MOPP), and CQC GB4943.1 certifications. Its AEC-Q100 qualification (Grade 1) and * marking on the package confirm VDE 0884-17 compliance - distinct from non-W variants lacking automotive validation.
Can the ADuM6028-5WBRIZ-RL replace the ADuM6020-5WBRIZ-RL in a design?
No - the ADuM6028-5WBRIZ-RL (8-lead, 60 mA) and ADuM6020-5WBRIZ-RL (16-lead, 100 mA) differ in package, output current, thermal resistance (θJA = 80 vs. 45 °C/W), and pin count. They are not pin-compatible. Substitution requires PCB redesign, layout review for creepage/clearance, and verification of load current and thermal margin.
