Analog Devices Inc. ADUM6020-5WBRIZ-RL

Overview

ADUM6020-5WBRIZ-RL from Analog Devices is a 5 kV rms isolated, integrated dc-to-dc converter in a wide-body 16-lead SOIC_IC package, delivering up to 100 mA at 5 V output from a 5 V input, with 33% efficiency at full load, CISPR22 Class B emissions compliance on 2-layer PCBs, and AEC-Q100 qualification for automotive use.

For engineers reviewing the ADUM6020-5WBRIZ-RL datasheet, ADUM6020-5WBRIZ-RL pinout, ADUM6020-5WBRIZ-RL application, or ADUM6020-5WBRIZ-RL equivalent, this device serves as a compact, safety-certified power source for isolated interfaces-especially where space-constrained, low-noise, and high-reliability biasing of RS-485/RS-422/CAN transceivers or sensor front-ends is required.

Technical Context

The ADUM6020-5WBRIZ-RL integrates iCoupler® chip-scale transformers and isoPower® regulation circuitry to deliver galvanically isolated 5 V output from a 5 V primary supply, operating at 625 kHz PWM frequency and 180 MHz switching frequency. It implements undervoltage lockout (rising threshold 4.1 V, falling 3.3 V) and thermal shutdown at 154°C with 10°C hysteresis.

Its isolation barrier meets reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17), with VIORM = 565 V peak, VISO = 5000 V rms (1 min), and minimum creepage/clearance of 8.3 mm. Input-to-output capacitance is 2.2 pF at 1 MHz, and junction-to-ambient thermal resistance is 45°C/W.

Key Specifications

Pinout & Package

ADUM6020-5WBRIZ-RL uses a 16-lead SOIC_IC wide-body package with 8.3 mm minimum creepage and clearance. Input-side pins (1–8) and output-side pins (9–16) are grouped for functional separation; GND1 and GNDISO are isolated ground references.

FAQ

What is the maximum continuous output current of the ADUM6020-5WBRIZ-RL?

The ADUM6020-5WBRIZ-RL delivers up to 100 mA at 5 V output under recommended conditions (TA ≤ 85°C). Above 85°C, output current is derated linearly by 1.75 mA per °C-so at 105°C, max output drops to 61.25 mA. This rating assumes proper PCB thermal design per JEDEC JESD-51 standards.

Does the ADUM6020-5WBRIZ-RL require external components for basic operation?

Yes-the ADUM6020-5WBRIZ-RL requires two external bypass capacitors: a 0.1 µF ceramic capacitor and a 10 µF bulk capacitor (both placed at the VISO pin), plus appropriate input decoupling at VDDP. No external transformer, controller, or feedback network is needed, as all isolation and regulation are integrated within the ADUM6020-5WBRIZ-RL die.

Can the ADUM6020-5WBRIZ-RL be used with a 3.3 V input supply?

No-the ADUM6020-5WBRIZ-RL is specifically configured for 5 V primary input (4.5–5.5 V range). For 3.3 V input operation, Analog Devices specifies the ADUM6020-3BRIZ or ADUM6020-3WBRIZ-RL variants. Using 3.3 V on the ADUM6020-5WBRIZ-RL's VDDP pin falls below its undervoltage lockout rising threshold (4.1 V typical) and will prevent startup.

What safety certifications does the ADUM6020-5WBRIZ-RL hold?

The ADUM6020-5WBRIZ-RL is certified to UL 1577 (5000 V rms, 1 min), IEC/EN/CSA 62368-1, IEC/CSA 61010-1, IEC/CSA 60601-1 (2 MOPP), and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 565 V peak. It also carries CQC GB 4943.1 approval and AEC-Q100 qualification for automotive use.

How does the PDIS pin function on the ADUM6020-5WBRIZ-RL?

The PDIS (Power Disable) pin on the ADUM6020-5WBRIZ-RL controls VISO output enablement: tying PDIS to any GND1 pin activates the output; applying a logic high voltage (≥2.0 V) disables VISO. The pin must never be left floating-uncontrolled states may cause erratic behavior. No pull-up or pull-down resistor is required if actively driven.
