Product details
Overview
mEZDPD3603A-84E8 from Monolithic Power Systems is a fully integrated, programmable 36V-input DC/DC power supply module delivering up to 3A continuous output current with user-configurable 0.6–12V output voltage, I²C-based parameter programming (output voltage, current limit, switching frequency), and built-in EN, PG, and fault signaling - deployed in industrial control power rails and FPGA core supplies.
For engineers reviewing the mEZDPD3603A-84E8 datasheet, mEZDPD3603A-84E8 pinout, mEZDPD3603A-84E8 application, or mEZDPD3603A-84E8 equivalent, this module supports rapid bench evaluation via USB-to-I²C interface, offers OTP+RAM programmability, meets EN55022 Class B emissions, and provides thermal shutdown at 175°C with hiccup-mode short-circuit protection.
Technical Context
The mEZDPD3603A-84E8 integrates a synchronous buck controller, power MOSFETs, compensation network, and internal 5V LDO (VCC) into a single DIP package. It operates across 4.5–36V input and supports I²C address selection via external resistor (R2) for multi-module systems.
Its programmable architecture enables real-time tuning of output voltage (±1% accuracy), current limit, and switching frequency (typ. 500 kHz); all non-volatile settings are stored in one-time-programmable ROM, while runtime adjustments use volatile RAM registers accessible over I²C.

FAQ
What is the difference between OTP and RAM programming on the mEZDPD3603A-84E8?
OTP (one-time programmable ROM) stores permanent configuration parameters like default output voltage and current limit; it is written once during manufacturing or final test. RAM registers allow unlimited runtime writes over I²C for temporary adjustments such as dynamic voltage scaling or fault logging - values reset on power cycle unless copied to OTP.
Can multiple mEZDPD3603A-84E8 modules share the same I²C bus?
Yes - each module uses an external resistor on the ADD pin to select a unique 7-bit I²C slave address (e.g., 21h–26h). Up to six modules can coexist on one bus without address conflict, enabling synchronized configuration or telemetry polling in multi-rail systems.
Does the mEZDPD3603A-84E8 require external compensation components?
No - all compensation networks are fully integrated. The module uses internal Type III compensation optimized for standard 4.7 µH inductors and 22 µF output capacitors. No external resistors or capacitors are needed for stability across its full 0.6–12 V output range.
What is the role of the VCC pin, and what load can it drive?
VCC is the output of an internal 5 V, 100 mA LDO regulator powered from VIN. It supplies clean bias for external logic, level shifters, or monitoring ICs. Load must remain ≤100 mA; exceeding this may cause VCC droop and affect I²C communication reliability.
How does the FT̅ (Fault) pin behave during overtemperature events?
FT̅ asserts low during overtemperature (OTP trip at 175 °C), overcurrent, or input undervoltage. It remains latched low until the fault condition clears and the device completes a full restart cycle - either via EN toggle or VIN power cycle - ensuring persistent fault visibility to host controllers.
Is the mEZDPD3603A-84E8 RoHS and REACH compliant?
Yes - the module complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full material declarations and certificate of compliance are available through Monolithic Power Systems' official distributor portal and technical support team.
