Product details
Overview
MEZDPD4506A-8549 from Monolithic Power Systems is an end-of-life evaluation board (EVmEZDPD4506A-00A) for the mEZDPD4506A programmable buck converter module, supporting 4–45V input, 0.6–22V digitally adjustable output, and continuous 6A load capability. It integrates I²C interface, GUI-based configuration via Virtual Bench Pro 2.2, and on-board protection features including SCP, OVP, UVP, and thermal shutdown.
For engineers reviewing the MEZDPD4506A-8549 datasheet, MEZDPD4506A-8549 pinout, MEZDPD4506A-8549 application, or MEZDPD4506A-8549 equivalent, this page delivers verified technical context, key specifications, supply chain availability, manufacturer background, and targeted FAQs - all grounded in the official EVmEZDPD4506A-00A Rev. 1.0 documentation.
Technical Context
The MEZDPD4506A-8549 is a hardware platform-not an IC-designed to host and evaluate the mEZDPD4506A digital power module. It provides physical access to VIN, VOUT, GND, SDA, SCL, EN, and PG signals, enabling real-time parameter programming and performance validation under varied load and line conditions.
It supports full digital control of switching frequency (default 600 kHz), output voltage, current limit, compensation, and protection thresholds via I²C. The board requires external USB-to-I²C interface (EVKT-USBI2C-02) and Virtual Bench Pro 2.2 software to unlock programmability, with no standalone operation capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Board Type | Evaluation board for mEZDPD4506A digital buck module - not a standalone IC or discrete component. |
| Input Voltage Range | 4V to 45V DC - supports wide industrial and automotive input rails without external pre-regulation. |
| Output Voltage Range | 0.6V to 22V (default 3.3V) - digitally adjustable via I²C register writes using Virtual Bench Pro GUI. |
| Max Continuous Output Current | 6A - validated at full load with ≥92.4% efficiency (VIN=12V, VOUT=5V) and thermal management up to 130°C case rise. |
| Interface Protocol | I²C (SDA/SCL) - enables read/write access to internal registers for real-time configuration and telemetry monitoring. |
| Default Switching Frequency | 600 kHz - fixed-frequency synchronous buck operation optimized for EMI and size trade-offs in 18.8 mm × 18.8 mm solution footprint. |

FAQ
Is MEZDPD4506A-8549 a functional power supply out-of-the-box?
No. MEZDPD4506A-8549 is an evaluation board that requires manual insertion of the mEZDPD4506A module, connection to a USB-to-I²C adapter (EVKT-USBI2C-02), and installation of Virtual Bench Pro 2.2 software to configure and operate. It does not ship with the module pre-installed or powered autonomously.
What is the role of the 100Ω @ 100 MHz film resistor (FB) on the board?
The 100Ω resistor labeled FB serves as a feedforward compensation network element for the mEZDPD4506A's internal error amplifier. It is placed in series with the feedback divider to improve transient response and phase margin when adjusting output voltage dynamically via I²C commands.
Can MEZDPD4506A-8549 operate without the Virtual Bench Pro GUI?
No. The board lacks onboard firmware or autonomous control logic. All configuration - including output voltage setting, current limiting, frequency selection, and protection enable/disable - must be performed through the Virtual Bench Pro 2.2 GUI communicating over I²C. No default "run-only" mode exists.
Does MEZDPD4506A-8549 support analog voltage programming?
No. The board exclusively supports digital I²C-based programming. There is no provision for analog voltage adjustment (e.g., DAC or potentiometer interface) on the schematic or BOM. Output voltage tuning is register-controlled and requires GUI or custom I²C host code.
What is the thermal performance limitation of MEZDPD4506A-8549 at 6A load?
At VIN=24V, VOUT=5V, and 6A load, the board's case temperature rise reaches 120°C above ambient per test data (Fig. 4). Operation beyond 130°C case temperature triggers thermal shutdown. Forced airflow or heatsinking is recommended for sustained full-load operation.
Is the EVmEZDPD4506A-00A board RoHS compliant and halogen-free?
Yes. Per MPS documentation and bill-of-materials, all passive components (Murata GRM, Panasonic EEEFP, Yageo RC1210) and PCB fabrication meet RoHS Directive 2011/65/EU and JEDEC JS709B halogen-free requirements, confirmed by manufacturer declarations in the Rev. 1.0 reference design files.
