Monolithic Power Systems Inc. PKT-MEZDPD4506A-84E0

Overview

PKT-MEZDPD4506A-84E0 from Monolithic Power Systems is an evaluation kit containing the EVmEZDPD4506A-00A programmable DC/DC buck evaluation board, mEZDPD4506A module (4–45V input, 0.6–22V output, 6A continuous), USB-to-I²C interface (EVKT-USBI2C-02), and GUI software drive (Tdrive-mEZDPD4506A). It enables full digital configuration of output voltage, switching frequency (600 kHz default), current limit, and protection modes via Virtual Bench Pro 2.2.

For engineers reviewing the PKT-MEZDPD4506A-84E0 datasheet, PKT-MEZDPD4506A-84E0 pinout, PKT-MEZDPD4506A-84E0 application, or PKT-MEZDPD4506A-84E0 equivalent, this kit supports rapid validation of high-efficiency, digitally programmable 45V-input power supplies in industrial control, test equipment, and FPGA/ASIC auxiliary rails where adjustable regulation, I²C-based telemetry, and fast transient response are required.

Technical Context

The PKT-MEZDPD4506A-84E0 integrates a complete evaluation ecosystem for the mEZDPD4506A digital PMIC module - a fully integrated, multiple-time programmable buck converter with internal MOSFETs, compensation, and real-time telemetry. It operates across 4–45V input and delivers up to 6A at 0.6–22V output with peak efficiency of 94.4% (VIN=24V, VOUT=12V, 6A).

Configuration and monitoring occur over I²C using Virtual Bench Pro 2.2 GUI, enabling dynamic adjustment of output voltage, switching frequency, overcurrent threshold, soft-start time, and fault response (SCP, OVP, UVP, thermal shutdown). The board includes on-board input/output filtering, sense resistors, and EMI mitigation components per MPS reference design.

FAQ

Is the PKT-MEZDPD4506A-84E0 still in production?

No - the EVmEZDPD4506A-00A evaluation board included in this kit is marked END OF LIFE per the official revision 1.0 documentation dated February 2019. Aetrix Electronics maintains limited legacy stock for design continuity and replacement needs in existing programs.

What software is required to configure the mEZDPD4506A module?

Virtual Bench Pro 2.2 GUI is mandatory and supplied on the included Tdrive-mEZDPD4506A USB thumb drive. It provides full register-level access to output voltage, switching frequency, current limit, soft-start, and protection thresholds via the EVKT-USBI2C-02 interface.

Can the PKT-MEZDPD4506A-84E0 operate without connecting to a PC?

Yes - once programmed, the mEZDPD4506A module retains its configuration in non-volatile memory. The board functions as a standalone 4–45V input, 0.6–22V/6A buck supply without ongoing PC connection or GUI interaction.

What is the physical size of the EVmEZDPD4506A-00A board?

The evaluation board measures 64mm × 64mm, matching the mechanical footprint shown in the printed circuit board layout (Figures 1–4). The mEZDPD4506A module itself occupies an 18.8mm × 18.8mm solution area on the board.

Does the kit include the mEZDPD4506A module?

Yes - the PKT-MEZDPD4506A-84E0 contains one mEZDPD4506A-0000 module pre-configured to default settings (3.3V output, 600 kHz switching frequency), ready for socket insertion onto the EVmEZDPD4506A-00A board.

What protection features are implemented on the board?

The board implements overcurrent protection (SCP), overvoltage protection (OVP), undervoltage lockout (UVLO), and thermal shutdown. These are configurable via I²C and verified in typical performance waveforms (EN start-up, SCP entry/recovery, load transients).
