company blog about Mingjiada Electronics [Supply + Recycling] ADI EVAL-ADPL54203-AZ Ultra-Low Power Isolated Flyback Evaluation Board

Mingjiada Electronics provides professional services for your project development and asset disposal regarding the supply and recycling of the ADI EVAL-ADPL54203-AZ evaluation board. This high-performance power solution is designed for evaluation and prototyping.

EVAL-ADPL54203-AZ Evaluation Board Product Details:

The EVAL-ADPL54203-AZ evaluation board demonstrates a micro-power, no-opto-isolated flyback converter utilising the ADPL54203. This demonstration circuit outputs a 5V voltage, maintaining precise regulation across a 10V to 28V input range for load currents from 10mA to 2.2A. The output current capability increases with rising input voltage. The minimum load required for the ADPL54203 to maintain good output voltage regulation typically does not exceed 0.5% of its full output power.

To avoid preloading, the Analog Devices EVAL-ADPL54203-AZ employs a 5.6V Zener diode between VOUT+ and VOUT– as the minimum load. Transformer leakage inductance generates voltage spikes on the primary side after power shutdown. To confine leakage inductance spikes within the MOSFET's 60V rating, an RC snubber and TVS clamp are installed to suppress ringing and clamp the MOSFET drain voltage to a safe level.

Key Specifications:

Core Chip: ADPL54203 Non-Optically Isolated Flyback Converter

Input Voltage: 10V to 28V (typical 24V)

Output Voltage: 5V (range: 4.75V to 5.25V)

Output Current: Maximum 2.2A

Switching Frequency: Typical 345kHz

Key Features: Voltage regulation without optical isolators or transformer third windings; low ripple burst mode at light loads

Typical Applications: Isolated auxiliary power supplies, industrial and medical power supplies

Core Features and Advantages:

The EVAL-ADPL54203-AZ evaluation board centres on its ADPL54203 chip, which integrates a 3.4A, 60V DMOS power switch. This board offers the following significant advantages:

Simplified Isolated Power Supply Design: The ADPL54203 regulates by directly sampling the isolated output voltage from the primary-side flyback waveform. This eliminates the need for optocouplers or a third transformer winding commonly found in traditional isolated power supplies, thereby simplifying design and saving space.

High efficiency and flexibility:

Quasi-resonant boundary mode operation under heavy loads facilitates compact magnetic component solutions and excellent load regulation.

During light loads, low-ripple burst mode minimises output voltage ripple while maintaining high efficiency.

The board design is easily modifiable and, when paired with a pre-designed transformer, adapts to diverse application requirements.

Comprehensive Protection Measures: The evaluation board incorporates output short-circuit protection. Additionally, an RC snubber and TVS clamp are installed to suppress voltage spikes and ringing caused by transformer leakage inductance, limiting MOSFET drain voltage to safe levels.
