Product details
Overview
mEZDPD3603A-84F0 from Monolithic Power Systems is a programmable, fully integrated DC/DC power supply module delivering up to 3A output current with adjustable 0.6–12V output voltage, operating from 4.5–36V input, housed in a standard DIP package (16×23×6.5 mm), and featuring I²C-based configuration for bench evaluation and system integration in industrial control power rails.
For engineers reviewing the mEZDPD3603A-84F0 datasheet, mEZDPD3603A-84F0 pinout, mEZDPD3603A-84F0 application, or mEZDPD3603A-84F0 equivalent, this module supports rapid prototyping via USB-to-I²C interface, OTP/RAM programming of output voltage, current limit, switching frequency, and compensation-enabling precise power rail tuning without hardware changes.
Technical Context
The mEZDPD3603A-84F0 integrates a synchronous buck controller, power MOSFETs, inductor, and input/output capacitors into a single surface-mount DIP module. It implements hiccup-mode short-circuit protection and thermal shutdown at 175°C, with internal 5V LDO (VCC) powering control circuitry independently of VOUT.
Configuration occurs over I²C using a GUI-driven virtual bench environment; parameters stored in one-time-programmable (OTP) ROM persist across power cycles, while RAM registers allow unlimited runtime adjustments. The SYNC pin enables external clock synchronization for noise-sensitive multi-rail systems.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SYNC | Synchronization Input | Accepts external clock signal to align switching frequency with other power rails, reducing beat-frequency EMI. |
| 2 EN | Enable Control | Active-high logic input; drives high to enable regulation, low to shut down with soft-start disabled. |
| 3 GND | Power Ground | Main return path for high-current VIN/VOUT loops; requires low-impedance connection to large ground plane. |
| 4 VIN | Input Supply | Primary DC input (4.5–36 V); routed with short, wide traces to minimize voltage drop and ringing. |

| 8 GND | Power Ground | Second dedicated ground terminal to reduce ground loop impedance and improve noise immunity. |
| 9 VOUT | Regulated Output | Primary regulated DC output (0.6–12 V); connects directly to load with low-ESR ceramic capacitor bank. |
| 10 VCC | Internal LDO Output | Stable 5 V output powering internal logic; must be decoupled locally with ≥1 µF X7R ceramic capacitor. |
| 11 SDA | I²C Data Line | Bi-directional open-drain data line for parameter read/write; requires 4.7 kΩ pull-up to VCC. |

FAQ
What is the difference between OTP and RAM programming modes?
OTP (one-time programmable) memory stores configuration permanently-once written, values persist across all power cycles and cannot be overwritten. RAM registers allow unlimited read/write access for runtime tuning, but settings reset on power loss unless reloaded from OTP or host controller. OTP is used for final production calibration; RAM supports lab evaluation and dynamic control.
Can mEZDPD3603A-84F0 operate without external input/output capacitors?
No. External input (≥4.7 µF ceramic) and output (≥22 µF ceramic) capacitors are mandatory per datasheet layout guidelines. Omitting them causes instability, excessive ripple, and potential failure under load. The module integrates passive components but relies on external bulk and high-frequency decoupling for regulation integrity and EMI compliance.
How is the I²C address set, and what addresses are supported?
The ADD pin sets the I²C slave address via an external resistor to GND. Supported addresses are 21h through 26h, corresponding to resistor values of 0 kΩ, 37.5 kΩ, 62.5 kΩ, 87.5 kΩ, 112.5 kΩ, and 137.5 kΩ. This allows up to six identical modules on a single I²C bus without address conflict.
Does mEZDPD3603A-84F0 include overvoltage protection (OVP)?
No. The device does not implement output overvoltage protection. It provides overcurrent (hiccup mode), overtemperature (175°C shutdown), and input undervoltage lockout (UVLO). System-level OVP must be implemented externally if required-for example, using a discrete supervisor IC monitoring VOUT and disabling EN.
What is the purpose of the SYNC pin, and can it be left unconnected?
The SYNC pin accepts an external clock (500 kHz typical) to synchronize switching frequency across multiple modules, reducing beat-frequency EMI. It may be left floating or tied to GND if synchronization is not needed; the internal oscillator operates autonomously. Pulling high is not allowed and may damage the pin.
Is the VCC pin intended for external use as a 5 V supply?
VCC is an internal 5 V LDO output designed solely to power the module's control circuitry. It is not rated for external loading beyond its specified 10 mA sink/source capability. Connecting external loads risks regulation failure, thermal overload, and loss of PG/FT̅ functionality. Use only for local decoupling.
