Product details
Overview
mEZDPD3603A-0001 from Monolithic Power Systems is a fully integrated, programmable DC/DC power module delivering up to 3A at 5V output from a 4.5–36V input. It integrates controller, MOSFETs, inductor, and compensation into a standard DIP package (16×23×6.5 mm), with factory-programmed OTP configuration for immediate use in industrial power rails, embedded controllers, and test equipment.
For engineers reviewing the mEZDPD3603A-0001 datasheet, mEZDPD3603A-0001 pinout, mEZDPD3603A-0001 application, or mEZDPD3603A-0001 equivalent, this module supports I²C-based real-time reconfiguration of output voltage (0.6–12V), current limit, switching frequency (500 kHz typical), and protection thresholds - enabling rapid bench validation without hardware changes.
Technical Context
The mEZDPD3603A-0001 implements a synchronous buck topology with integrated high-side and low-side MOSFETs, internal 5V LDO (VCC), and digital control via I²C interface. Its programmable OTP memory stores default settings including 5V/3A output, hiccup-mode short-circuit protection, and 175°C over-temperature shutdown.
It features active compensation tuning, EN-controlled soft-start, power-good (PG) and fault (FT) open-drain status signals, and SYNC input for external clock synchronization. Input ripple suppression is optimized for EN55022 Class B compliance using recommended 4.7 µF CIN and dual 22 µF COUT capacitors.

Pinout & Package
Package: Standard DIP module, 16 mm × 23 mm × 6.5 mm, with exposed thermal pad on bottom side for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SYNC | Clock Synchronization Input | Accepts external clock signal to synchronize switching frequency and reduce beat-frequency EMI in multi-module systems. |
| 2 EN | Enable Control Input | Active-high logic input; drives internal soft-start and UVLO when pulled high; supports sequencing with upstream supplies. |
| 3 GND | Power Ground | Main return path for input, output, and internal regulator currents; requires low-impedance connection to PCB ground plane. |
| 4 VIN | Input Supply | Primary DC input (4.5–36 V); connects to bulk capacitor and EMI filter; high-current path requiring wide copper trace. |
| 5 FT̅ | Fault Indicator Output | Open-drain output asserted low during over-current, over-temperature, or undervoltage fault; requires pull-up resistor. |
| 6 PG | Power Good Output | Open-drain output asserted high after VOUT reaches 90 % of target and remains stable for >1 ms; used for system power sequencing. |
| 7 ADD | I²C Address Selection | Configures slave address (e.g., 21h–26h) by connecting to GND or specific resistor values; enables multi-module I²C bus operation. |
| 8 GND | Power Ground | Second dedicated ground terminal to minimize noise coupling between analog and power sections. |
| 9 VOUT | Regulated Output | Primary 5 V (default) output; connects to load capacitance and downstream regulators; requires low-ESR ceramic capacitors. |
| 10 VCC | Internal LDO Output | 5 V regulated supply for internal circuitry; must be decoupled with ≥1 µF ceramic capacitor placed adjacent to pin. |
| 11 SDA | I²C Data Line | Bi-directional serial data line for programming registers and reading telemetry (e.g., temperature, output voltage). |
| 12 SCL | I²C Clock Line | Master-generated clock input for I²C communication; supports standard (100 kHz) and fast (400 kHz) modes. |
Key Features
| Feature | Design Value |
|---|---|
| One-Time Programmable (OTP) Memory | Stores final configuration (VOUT, IOUT limit, FSW) permanently; eliminates need for external EEPROM or firmware bootloaders. |
| I²C Interface with GUI Support | Enables real-time parameter adjustment and performance modeling via Virtual Bench Pro GUI; no custom firmware required. |
| Hiccup-Mode Short-Circuit Protection | Automatically cycles ON/OFF during sustained overload, limiting average power dissipation and preventing thermal runaway. |
| EN-Controlled Soft-Start | Gradually ramps output voltage over ~1 ms to prevent inrush current and avoid supply droop on shared input rails. |
| Integrated Thermal Shutdown | Triggers at 175 °C junction temperature and holds until cooldown; protects against sustained overloads or poor heatsinking. |

FAQ
What is the difference between mEZDPD3603A-0001 and non-programmed mEZDPD3603A-XXXX parts?
The mEZDPD3603A-0001 is factory-programmed with 5 V output, 3 A current limit, and 500 kHz switching frequency - ready for immediate use. Non-programmed variants (mEZDPD3603A-XXXX) require initial I²C configuration before operation; they share identical hardware but ship with blank OTP memory and default RAM settings.
Can the output voltage be changed after OTP programming?
No - OTP memory is write-once. However, runtime register (RAM) values - including output voltage - can be modified infinitely via I²C until power cycle. After reboot, the device reverts to OTP-stored values unless "save to OTP" is explicitly executed, which permanently overwrites prior settings.
Does mEZDPD3603A-0001 require external compensation components?
No - all compensation is implemented internally and automatically adjusted based on programmed output voltage and current limits. The module includes built-in loop stability optimization, eliminating external RC networks or type-II/type-III compensators required in discrete buck controllers.
What is the purpose of the ADD pin, and how is it configured?
The ADD pin sets the I²C slave address (21h–26h) by connecting to GND through one of six standard resistor values (0 kΩ to 137.5 kΩ). This enables up to six mEZDPD3603A modules on a single I²C bus without address conflict, supporting scalable multi-rail power systems.
Is an evaluation board required to configure mEZDPD3603A-0001?
No - configuration is possible using any I²C master (e.g., Arduino, Raspberry Pi) and the open-register map. However, the EVmEZDPD3603A-00A evaluation board with EVKT-USBI2C-02 interface simplifies setup and provides validated layout, thermal management, and GUI integration for rapid prototyping.
How does the PG (Power Good) signal behave during startup and fault conditions?
The PG pin asserts high only after VOUT reaches ≥90 % of target and remains within regulation for >1 ms. It goes low during input UVLO, output overvoltage, over-temperature, or short-circuit events - providing precise sequencing feedback to host controllers without debouncing delays.
What are the thermal management requirements for continuous 3 A operation?
At VIN=24 V, VOUT=5 V, full load, case temperature rise is ≤60 °C above ambient. A 4-layer PCB with internal ground plane, ≥6 thermal vias under the module's exposed pad, and ≥2 cm² copper area per amp is recommended. No heatsink is required below 60 °C ambient.
