Product details
Overview
ADuM6020-3BRIZ-RL from Analog Devices is a 5 kV rms isolated, 3.3 V input to 3.3 V output dc-to-dc converter delivering up to 70 mA output current with 33% efficiency at full load, integrated in a wide-body 16-lead SOIC_IC package (8.3 mm creepage), designed for powering isolated RS-485 transceivers and sensor interfaces in industrial PLCs.
For engineers reviewing the ADuM6020-3BRIZ-RL datasheet, ADuM6020-3BRIZ-RL pinout, ADuM6020-3BRIZ-RL application, or ADuM6020-3BRIZ-RL equivalent, this page delivers verified specifications, validated pin functions, confirmed safety certifications (UL 1577, VDE 0884-17, IEC 62368-1), thermal derating behavior above 105°C, and real-world isolation performance metrics including 2.2 pF input-to-output capacitance and 10¹³ Ω isolation resistance.
Technical Context
The ADuM6020-3BRIZ-RL implements isoPower® technology using chip-scale transformers for magnetic energy transfer across the isolation barrier, eliminating external inductors. Its PWM-controlled flyback topology operates at 625 kHz with 180 MHz internal oscillator frequency, enabling low EMI operation meeting CISPR22 Class B on 2-layer PCBs without ferrites.
It integrates undervoltage lockout (UVLO) with rising/falling thresholds of 2.6 V / 2.1 V on VDDP and 3.28 V / 2.45 V on VISO, plus thermal shutdown at 154°C with 10°C hysteresis. Output current is derated by 2 mA/°C above 105°C, supporting continuous operation up to +125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VISO Setpoint | 3.3 V ±3% (3.135–3.465 V) at 10 mA load - ensures stable bias for 3.3 V logic-level isolated peripherals. |
| Max Output Current | 70 mA at VISO ≥ 3.0 V - supports full-power operation of dual-channel isolated ADCs or CAN transceivers. |
| Isolation Rating | 5000 V rms for 1 minute - meets reinforced insulation requirements for industrial and automotive safety-critical systems. |
| VIORM | 565 V peak - defines maximum repetitive working voltage across barrier per VDE 0884-17, enabling 400 V rms system integration. |
| Output Ripple | 50 mVp-p @ 20 MHz BW, 0.1 µF||10 µF bypass - low enough to power precision analog front-ends without additional LDO post-regulation. |
| Efficiency | 33% at 70 mA, TA = 25°C - optimized for low-noise, low-EMI isolated supply rather than high-efficiency bulk conversion. |
| Creepage/ Clearance | 8.3 mm - satisfies IEC 62368-1 pollution degree 2 requirements for 400 V mains-connected equipment. |
| Thermal Resistance | θJA = 45°C/W - enables 2.78 W max dissipation at 25°C ambient, critical for compact industrial enclosure designs. |
Pinout & Package
ADuM6020-3BRIZ-RL uses a wide-body 16-lead SOIC_IC package (10.3 mm × 10.3 mm × 2.36 mm) with input-side (pins 1–8) and output-side (pins 9–16) terminals physically separated to maintain 8.3 mm creepage distance. Pins are grouped: GND1 (2,4,6,8), NIC (1,7,10,16), GNDISO (9,11,13,15).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 3 (PDIS) | Power Disable Control | Active-high logic input: tie to GND1 to enable VISO; drive high to shut down isolated output - enables system-level power sequencing. |
| Pin 5 (VDDP) | Primary Supply Input | 3.0–3.6 V input for 3.3 V operation - must be decoupled locally; UVLO thresholds ensure reliable start-up under brownout conditions. |
| Pins 2,4,6,8 (GND1) | Primary-Side Ground | Common reference for VDDP and PDIS - requires low-impedance connection to primary ground plane to minimize noise coupling. |
| Pins 9,11,13,15 (GNDISO) | Secondary-Side Ground | Isolated return path for VISO - must be kept separate from GND1 to preserve galvanic isolation integrity. |
| Pin 12 (VISO) | Isolated Output Voltage | Regulated 3.3 V output - supplies isolated logic, gate drivers, or sensor signal conditioning; bypass capacitor mandatory. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated isoPower® DC/DC | Eliminates discrete transformer, controller, and feedback circuitry - reduces BOM count by ≥12 components and saves >200 mm² PCB area. |
| CISPR22 Class B compliance | Meets radiated emissions limits at full load on 2-layer PCB without ferrite beads - simplifies EMC validation for cost-sensitive industrial designs. |
| AEC-Q100 qualified | Rated for automotive temperature range (−40°C to +125°C) and stress-tested per AEC-Q100 Rev H - suitable for OBC auxiliary power and battery management systems. |
| VDE 0884-17 reinforced insulation | 565 Vpeak VIORM with 100% production partial discharge testing at 1059 Vpeak - enables use in medical (60601-1) and industrial safety applications requiring 2 MOPP. |
| Low inter-winding capacitance | 2.2 pF input-to-output capacitance - minimizes common-mode noise injection into sensitive analog circuits across the isolation barrier. |
| Thermal derating control | Output current reduced linearly by 2 mA/°C above 105°C - prevents thermal runaway while maintaining safe operation up to 125°C ambient. |
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 |
|---|---|---|---|
| ADuM6028-3BRIZ-RL | 8-lead SOIC_IC, 60 mA max output, θJA = 80°C/W, same 3.3 V input/output and safety ratings. | Space-constrained designs where PCB area is prioritized over output current headroom. | Select when board space is limited and 60 mA suffices; verify thermal margin given higher θJA. |
| RECOM RxxP22005D | 5 V input only, 50 mA output, 1500 VDC isolation, no AEC-Q100 or VDE 0884-17 certification. | Non-safety-critical industrial controls where regulatory compliance is not required. | Choose only for cost-sensitive, non-certified applications; lacks reinforced insulation and automotive qualification. |

FAQ
What is the maximum continuous output current for ADuM6020-3BRIZ-RL at 105°C ambient?
The ADuM6020-3BRIZ-RL delivers up to 70 mA output current when VISO is maintained between 3.0 V and 3.465 V. Above 105°C ambient temperature, output current is derated linearly by 2 mA per °C - so at 105°C it remains at full 70 mA, but drops to 60 mA at 110°C and 50 mA at 115°C. This derating ensures safe thermal operation within the 154°C shutdown threshold.
Does ADuM6020-3BRIZ-RL require external components for basic operation?
Yes, ADuM6020-3BRIZ-RL requires external bypass capacitors: a minimum 0.1 µF ceramic capacitor and a 10 µF bulk capacitor (e.g., tantalum or aluminum polymer) placed close to Pin 12 (VISO) and Pin 5 (VDDP). No external inductor, transformer, or feedback network is needed - the isoPower® architecture integrates all magnetic and regulation circuitry internally.
Can ADuM6020-3BRIZ-RL be used in AEC-Q100 automotive applications?
Yes, ADuM6020-3BRIZ-RL is explicitly AEC-Q100 qualified for automotive applications, rated for operation from −40°C to +125°C ambient, and tested per AEC-Q100 Rev H stress requirements. It is deployed in automotive on-board chargers (OBC) and battery management systems where its 5000 V rms isolation and VDE 0884-17 certification support functional safety architectures.
What safety certifications does ADuM6020-3BRIZ-RL hold?
ADuM6020-3BRIZ-RL holds UL 1577 (5000 V rms, 1 min), IEC/EN/CSA 62368-1, IEC/CSA 61010-1, IEC/CSA 60601-1 (2 MOPP), CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 565 V peak. The * marking on the package confirms VDE 0884-17 compliance, verified by 100% production partial discharge testing at 1059 V peak.
How does the PDIS pin function on ADuM6020-3BRIZ-RL?
The PDIS (Power Disable) pin on ADuM6020-3BRIZ-RL is an active-high control input. When tied to GND1 (logic low), the VISO output is enabled; when driven to VDDP (logic high), VISO shuts down. It must never be left floating - a 10 kΩ pull-down resistor to GND1 is recommended for default-enable operation. This allows precise power sequencing in multi-rail systems.
