Product details
Overview
PKT-MEZDPD3603A from Monolithic Power Systems is an end-of-life evaluation kit for the mEZDPD3603A programmable DC/DC power module, supporting output voltage range 0.6–12 V, up to 3 A load current, and input voltage range 4.5–36 V. It enables rapid bench evaluation of digital PMBus-configurable power supplies via I2C interface and includes hardware (EVB, USB-to-I2C adapter), GUI software, and pre-programmed module.
For engineers reviewing the PKT-MEZDPD3603A datasheet, PKT-MEZDPD3603A pinout, PKT-MEZDPD3603A application, or PKT-MEZDPD3603A equivalent, this kit supports real-time register-level configuration, OTP programming, thermal and UVLO behavior validation, and GUI-driven modeling of transient response and compensation-critical for industrial, embedded, and test-bench power system development.
Technical Context
The PKT-MEZDPD3603A integrates the EVmEZDPD3603A-00A evaluation board and EVKT-USBI2C-02 interface device to enable full digital control of the mEZDPD3603A module. It supports both volatile (RAM/I2C) and non-volatile (OTP) programming of 8 key registers: output voltage, switching frequency, current limit, soft-start time, power-good threshold, VIN enable threshold, compensation, and protection modes.
Hardware setup requires a Windows PC (XP or later), USB port, and ≥17.6 MB free space. The GUI operates in Direct Programming Mode with real-time read/write access and export capability. All I2C changes reset on power cycle; OTP writes are permanent and require VIN > 8 V during programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Kit Type | Evaluation kit for mEZDPD3603A digital DC/DC module - not a standalone IC or component. |
| Input Voltage Range | 4.5 V to 36 V - powers the EVB and enables testing across wide industrial input rails. |
| Output Capability | 0.6 V to 12 V, up to 3 A - covers common point-of-load (POL) requirements for FPGA, ASIC, and microprocessor cores. |
| Interface Protocol | I2C + PMBus - allows standard register access, telemetry reads (VOUT, IOUT, temperature), and fault logging. |
| Programming Modes | RAM (volatile, lost on power-down) and OTP (permanent, one-time write) - supports iterative tuning and final firmware lock-in. |
| EVB Dimensions | 6.4 cm × 6.4 cm - compact form factor suitable for lab benches and integration into custom test fixtures. |
| Software Requirement | MPS I2C GUI (Windows XP/7+, .NET Framework 4.0) - provides graphical register editor, modeling, and configuration export. |

FAQ
Is PKT-MEZDPD3603A still in production?
No. The PKT-MEZDPD3603A is officially marked END OF LIFE per the 2018 User Guide. Aetrix Electronics offers limited remaining stock with full documentation and legacy support, but no new manufacturing or revisions are planned.
What hardware components are included in the kit?
The kit contains four items: (1) EVmEZDPD3603A-00A evaluation board, (2) mEZDPD3603A-0001 preconfigured module, (3) EVKT-USBI2C-02 USB-to-I2C interface with cables, and (4) Tdrive-mEZDPD3603A USB thumb drive with GUI installer and documents.
Can I reprogram the mEZDPD3603A module after OTP programming?
Yes - I2C RAM-mode programming remains fully functional after OTP. However, OTP-written values persist across power cycles, while RAM-mode changes are volatile and reset on power-down. Repeated OTP attempts on an already-programmed device have no effect.
Does the kit support Linux or macOS?
No. The MPS I2C GUI software is Windows-only (XP, 7, or later) and requires .NET Framework 4.0. No official Linux or macOS drivers or GUI versions were released for this kit.
What happens if I apply VIN below 4.5 V?
The module enters under-voltage lockout (UVLO). Its functions disable until VIN rises above the UVLO rising threshold (~4.5 V); if VIN then falls below the UVLO falling threshold (~4.2 V), it shuts down immediately - a safety feature preventing erratic operation.
How do I verify successful OTP programming?
After writing in ROM Mode and cycling power, use the GUI's "Read" function to confirm register values match your OTP settings. Note: values appear only after power-on reset - unlike RAM mode, they won't display before cycling power.
Is EVKT-USBI2C-02 compatible with other MPS evaluation kits?
Yes. The EVKT-USBI2C-02 is a universal USB-to-I2C/PMBus interface used across multiple MPS digital power evaluation kits, including mEZDPD, MPQ series, and MP29xx families - with shared driver (USBXpress) and GUI compatibility.
