Product details
Overview
mEZDPD3603A-8561 from Monolithic Power Systems is a fully integrated, programmable DC/DC power supply module delivering up to 3A continuous output current with adjustable 0.6–12V output voltage, operating from 4.5–36V input. It integrates PWM controller, power MOSFETs, inductor, and compensation network in a DIP package (16×23×6.5 mm), and supports I²C-based configuration for output voltage, current limit, switching frequency, and protection thresholds - used in industrial control power rails and embedded system point-of-load regulation.
For engineers reviewing the mEZDPD3603A-8561 datasheet, mEZDPD3603A-8561 pinout, mEZDPD3603A-8561 application, or mEZDPD3603A-8561 equivalent, this module enables rapid evaluation via USB-to-I²C interface and GUI-driven OTP/RAM programming - critical for validating dynamic load response, EN/PG sequencing, and EMI-compliant Class B operation in compact board space.
Technical Context
The mEZDPD3603A-8561 implements a synchronous buck topology with internal high-side and low-side MOSFETs, fixed-frequency peak-current-mode control, and programmable soft-start. Its integrated 5V LDO (VCC) powers internal circuitry and can supply external bias, while SYNC input allows external clock synchronization to reduce beat frequencies in multi-module systems.
It features hiccup-mode short-circuit protection, over-temperature shutdown at 175°C, and programmable current-limit threshold. The device uses one-time programmable (OTP) ROM for persistent configuration storage and volatile RAM for unlimited runtime tuning - enabling iterative bench optimization without hardware changes.

FAQ
What is the difference between OTP and RAM programming modes?
OTP (one-time programmable) ROM stores permanent configuration such as default output voltage and protection thresholds - written once during manufacturing or final test. RAM allows unlimited runtime writes via I²C for lab tuning, telemetry readback, or dynamic adjustment during operation. OTP settings persist through power cycles; RAM settings reset on power-up unless loaded from OTP.
Can mEZDPD3603A-8561 operate without external capacitors?
No. External input (4.7 µF min) and output (22 µF min) ceramic capacitors are mandatory for stability, EMI compliance, and transient response. The module's internal control loop assumes these values; omitting them causes oscillation, poor regulation, or failure to start. Recommended part numbers and footprints are provided in the BOM on page 7 of the datasheet.
How is thermal performance validated?
Thermal performance is validated per MIL-HDBK-217F using a 4-layer PCB with 2 oz copper ground plane, 100% thermal pad solder coverage, and forced convection. At 3 A full load (VIN=24 V, VOUT=5 V), case temperature rise is ≤60°C above ambient. Derating curves show 2.5 A max at 85°C ambient with natural convection.
Does it support parallel operation for higher current?
No. The mEZDPD3603A-8561 does not include current-sharing circuitry or master/slave synchronization beyond SYNC pin clock alignment. Parallel operation is not supported or characterized. For >3 A, use a single higher-current module (e.g., mEZD81260A) or independent rails.
What I²C address options are available?
Seven I²C addresses are selectable via resistor on ADD pin: 0x21 (0 kΩ), 0x22 (37.5 kΩ), 0x23 (62.5 kΩ), 0x24 (87.5 kΩ), 0x25 (112.5 kΩ), 0x26 (137.5 kΩ), and 0x27 (open). Each address supports full read/write access to all registers, including telemetry, configuration, and fault logs.
Is EN pin compatible with 3.3 V logic?
Yes. The EN pin has a 1.2 V threshold with hysteresis and accepts 1.8 V, 3.3 V, or 5 V logic levels. It draws <1 µA and supports direct connection to MCU GPIO without level-shifting. Internal pull-down ensures safe default-off state when unconnected.
What safety certifications does it hold?
The mEZDPD3603A-8561 is not UL/IEC/EN certified as a standalone safety-isolated power supply. It is rated for functional insulation only and must be integrated into end-equipment complying with relevant safety standards (e.g., UL 62368-1). No reinforced or basic isolation is provided between VIN and VOUT.
