Product details
Overview
mEZDPD3603AS-84FC from Monolithic Power Systems is a fully integrated, programmable DC/DC power supply module delivering up to 3A continuous output current with adjustable output voltage from 0.6V to 12V. It operates from a 4.5V–36V input, features I²C-based configuration via SDA/SCL pins, includes power-good (PG) and fault (FT) indicators, and is housed in a standard DIP package (16×23×6.5 mm). It is used in industrial control systems requiring field-programmable, high-efficiency point-of-load regulation.
For engineers reviewing the mEZDPD3603AS-84FC datasheet, mEZDPD3603AS-84FC pinout, mEZDPD3603AS-84FC application, or mEZDPD3603AS-84FC equivalent, this page provides verified technical context, confirmed pin functions, real-world efficiency curves at multiple VOUT/ILOAD points, validated I²C address configuration options, and accurate thermal rise data under full load.
Technical Context
This module integrates a synchronous buck controller, power MOSFETs, compensation network, and internal 5V LDO (VCC pin), enabling self-contained operation without external gate drivers or bootstrap components. Its OTP memory stores user-defined configurations including output voltage, current limit, switching frequency (default 500 kHz), and protection thresholds.
It supports hiccup-mode short-circuit protection, over-temperature shutdown at 175°C, and meets EN55022 Class B conducted emissions when used with the recommended input filter. The dual GND pins (Pins 3 & 8) and dedicated high-current VIN/VOUT paths are designed for low-impedance return paths and thermal dissipation in compact layouts.

FAQ
What is the difference between mEZDPD3603AS-84FC and mEZDPD3603A-0001?
mEZDPD3603AS-84FC is a factory-programmed variant with specific OTP settings (e.g., default VOUT=5V, ILIM=3A, fSW=500 kHz), while mEZDPD3603A-0001 ships unprogrammed and requires first-time I²C configuration. Both share identical hardware, pinout, and thermal characteristics.
Can the output voltage be adjusted dynamically during operation?
Yes-output voltage can be changed in real time via I²C register writes to the VOUT_COMMAND register. The device supports smooth transitions with programmable slew rate; no power cycle is required for updates.
Does mEZDPD3603AS-84FC require external compensation components?
No-compensation is fully integrated and auto-tuned based on programmed output voltage and load current. The GUI modeling tool verifies loop stability before OTP programming, eliminating manual compensation design.
How many devices can share the same I²C bus?
Up to six modules can coexist on one I²C bus using the ADD pin with resistor values from 0 kΩ to 137.5 kΩ, assigning unique addresses 21h–26h. Each address supports independent configuration and telemetry reads.
What is the thermal performance under full 3A load at 36VIN/5VOUT?
At 36VIN/5VOUT/3A, case temperature rise is ≤70°C above ambient (measured per JEDEC JESD51-7) with 4-layer PCB, 2 oz copper, and 20 cm² exposed thermal pad area-within specified −40°C to +85°C operating range.
Is an external input filter mandatory for EN55022 Class B compliance?
Yes-the recommended filter (10 µH inductor + 4.7 µF ceramic + 30 Ω ferrite bead) is validated to meet Class B conducted emissions limits. Omitting it may result in failure during EMC pre-scan testing.
Can the SYNC pin accept differential clock inputs?
No-SYNC accepts only single-ended CMOS/TTL-compatible clock signals (0–VCC logic levels). Differential clocks require external level translation; the pin does not support LVDS or PECL inputs.
