Product details
Overview
mEZDPD3603AS-84D1 from Monolithic Power Systems is a fully integrated, programmable DC/DC power module delivering up to 3A continuous output current with adjustable 0.6–12V output voltage, operating from 4.5–36V input. It integrates power MOSFETs, compensation, and an I²C interface in a standard DIP package (16×23×6.5 mm), designed for rapid bench evaluation and embedded power rail customization in industrial control and test equipment.
For engineers reviewing the mEZDPD3603AS-84D1 datasheet, mEZDPD3603AS-84D1 pinout, mEZDPD3603AS-84D1 application, or mEZDPD3603AS-84D1 equivalent, this module supports real-time configuration of output voltage, current limit, switching frequency, and protection thresholds via GUI-driven I²C programming - eliminating external loop compensation design effort.
Technical Context
The mEZDPD3603AS-84D1 implements a synchronous buck topology with internal high- and low-side MOSFETs, fixed-frequency peak-current-mode control, and integrated 5V LDO (VCC) for biasing. Its programmable OTP memory stores final configuration, while RAM registers allow unlimited runtime tuning.
It features hiccup-mode short-circuit protection, over-temperature shutdown at 175°C, power-good (PG) and fault (FT) open-drain status outputs, and SYNC input for external clock synchronization - enabling coherent multi-rail sequencing in dense power systems.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SYNC) | Synchronization Input | Accepts external clock signal to align switching edges across multiple modules; prevents beat-frequency EMI. |
| 2 (EN) | Enable Control | Active-high logic input; controls soft-start and full-system power-up sequencing with external MCU or supervisor. |
| 3 & 8 (GND) | Power Ground | Dual ground pins reduce impedance in high-di/dt return paths; must be connected to low-inductance PCB ground plane. |
| 4 (VIN) | Main Input Supply | Primary DC input connection; requires local 4.7 µF ceramic capacitor per datasheet layout guidelines. |

| 7 (ADD) | I²C Address Select | Resistor-programmable pin setting I²C slave address (e.g., 21h–26h); enables multi-module bus addressing. |
| 9 (VOUT) | Regulated Output | Main power output terminal; connects directly to load with minimal trace inductance and local 22 µF ceramic capacitance. |
| 10 (VCC) | Internal LDO Output | 5 V regulated supply for internal circuitry; requires 1 µF decoupling capacitor near VCC–GND pins. |
| 11 (SDA) | I²C Data Line | Bidirectional serial data line; pulled up externally to VCC; supports standard/fast-mode I²C communication. |

FAQ
What is the difference between OTP and RAM programming modes?
In RAM mode, all configuration registers (output voltage, current limit, switching frequency) can be written unlimited times via I²C - ideal for lab evaluation and dynamic tuning. OTP mode permanently stores one configuration set into non-volatile memory; writing OTP requires 8–36 V input and causes a reboot. Once programmed, OTP values persist across power cycles and override RAM settings.
Does mEZDPD3603AS-84D1 require external compensation components?
No. The device integrates full Type-II compensation circuitry internally. No external resistors or capacitors are needed for loop stability - simplifying layout and eliminating tuning iterations. All compensation parameters are programmable via the Virtual Bench Pro GUI and stored in OTP or RAM.
Can multiple mEZDPD3603AS-84D1 modules be synchronized?
Yes. The SYNC pin accepts an external clock signal (300–1200 kHz) to align switching edges across multiple modules. Combined with programmable ADD pin addressing, this enables coherent multi-rail power sequencing and reduced system-level EMI peaks without inter-module skew.
What is the thermal performance under full 3 A load?
At VIN = 24 V, VOUT = 5 V, and ambient 25°C with standard 4-layer PCB (2 oz copper, 10 cm² exposed ground plane), case temperature rise is ≤42°C at full 3 A load. Derating begins above 85°C case temperature, with thermal shutdown triggered at 175°C junction temperature.
Is EN pin compatible with 3.3 V logic microcontrollers?
Yes. The EN pin has a 1.2 V threshold with hysteresis and accepts 3.3 V CMOS logic levels directly. It does not require level-shifting when driven by common microcontrollers or FPGAs. Pull-down resistor (10 kΩ) is recommended for default-off behavior during power-up.
How is I²C address configured?
I²C address is set by connecting pin ADD to GND, VCC, or a resistor divider. Supported addresses are 21h–26h (hex), selected by resistor value (0 kΩ to 137.5 kΩ). This allows up to six identical modules on one I²C bus without address conflict - essential for multi-rail systems.
What input and output capacitors are required?
Minimum requirements: 4.7 µF X7R ceramic at VIN (1206), and two 22 µF X7R ceramics at VOUT (1206) for 5 V output. For 12 V output, CIN increases to 10 µF and COUT remains 22 µF ×2. All capacitors must be placed within 3 mm of respective pins per layout guidelines.
