Product details
Overview
mEZDPD3603AS-8501 from Monolithic Power Systems is a fully integrated, programmable DC/DC power supply module delivering up to 3A continuous output current with user-configurable 0.6–12V output voltage, 4.5–36V input range, and I²C-based parameter programming (output voltage, current limit, switching frequency, compensation). It operates in a standard DIP package (16×23×6.5 mm) and is used in industrial control, test equipment, and programmable bench supplies requiring rapid configuration iteration.
For engineers reviewing the mEZDPD3603AS-8501 datasheet, mEZDPD3603AS-8501 pinout, mEZDPD3603AS-8501 application, or mEZDPD3603AS-8501 equivalent, this page provides verified technical context, validated pin functions, real-world application cards, confirmed alternatives, and supply-chain support for volume procurement and BOM continuity.
Technical Context
The mEZDPD3603AS-8501 integrates a synchronous buck controller, power MOSFETs, gate drivers, internal 5V LDO (VCC), fault monitoring (PG, FT), and I²C interface (SCL/SDA) with address selection via ADD pin. It supports one-time OTP programming and unlimited RAM register writes for runtime reconfiguration.
It implements hiccup-mode short-circuit protection, over-temperature shutdown at 175°C, and meets EN55022 Class B emissions with recommended external filtering. Switching frequency is programmable (typ. 500 kHz or 800 kHz), and output voltage accuracy is ±1% under full load and line/load regulation conditions.
Key Specifications

Pinout & Package
Package: Standard DIP module, 16 mm × 23 mm × 6.5 mm, with exposed thermal pad on bottom side for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SYNC | Clock synchronization input | Accepts external clock signal to synchronize switching frequency across multiple modules and reduce beat-frequency EMI. |
| 2 EN | Enable control input | Active-high logic input; drives high to enable output; supports sequencing and remote on/off control. |
| 3, 8 GND | Power ground terminals | Dual low-impedance ground paths minimize noise coupling and improve thermal conduction to PCB ground plane. |
| 4 VIN | Main input power terminal | Accepts 4.5–36 V DC; requires local 4.7 µF ceramic input capacitor per layout guidelines. |
| 5 FT̅ | Fault indicator output | Open-drain active-low signal asserting during over-current, over-temperature, or undervoltage lockout events. |
| 6 PG | Power good output | Open-drain signal indicating regulated output within ±10% tolerance; used for system power sequencing and monitoring. |

| 9 VOUT | Regulated output terminal | Delivers up to 3 A at programmable 0.6–12 V; requires 22 µF output capacitance (x2 for 5 V/12 V outputs). |
| 10 VCC | Internal LDO output | 5 V regulated output powering internal circuitry; must be decoupled with 1 µF ceramic capacitor near pin. |
| 11 SDA | I²C serial data | Bi-directional open-drain data line for parameter read/write; supports standard/fast-mode I²C (100/400 kHz). |
| 12 SCL | I²C serial clock | Input-only clock line driving I²C communication; requires pull-up resistor to VCC or system VDD. |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the difference between mEZDPD3603AS-8501 and mEZDPD3603A-0001?
mEZDPD3603AS-8501 is a specific orderable variant pre-programmed with 5 V output, 3 A current limit, and 500 kHz switching frequency - matching the default configuration of mEZDPD3603A-0001. The "S" suffix denotes factory-programmed OTP content, ensuring consistent behavior without requiring initial GUI setup.
Can mEZDPD3603AS-8501 be reprogrammed after OTP programming?
No - the OTP (one-time programmable) ROM is permanently written during factory programming. However, all runtime registers (RAM) remain fully writable via I²C indefinitely, allowing dynamic adjustment of output voltage, current limit, and frequency during operation or testing.
Does mEZDPD3603AS-8501 require external compensation components?
No - the module integrates full Type II/III compensation circuitry. Users configure compensation digitally via the GUI; no external resistors or capacitors are needed for loop stability across the supported output voltage and load range.
What is the role of the ADD pin, and how is it configured?
The ADD pin sets the I²C slave address using an external resistor to GND. Values from 0 kΩ to 137.5 kΩ select addresses 21h–26h respectively, enabling up to six identical modules on a single I²C bus without address conflict.
Is thermal management required beyond PCB copper area?
Yes - while the DIP package includes an exposed thermal pad, optimal performance requires ≥4 cm² of 2-oz copper on the bottom layer connected via ≥6 thermal vias to internal ground planes. Case temperature rise remains ≤60°C at full load only with this layout.
How does the PG pin behave during startup and fault conditions?
PG asserts high after VOUT reaches 90% of target and remains high until VOUT drops below 90% or a fault (over-temp, short-circuit, UVLO) occurs. During hiccup-mode recovery, PG toggles low during fault intervals and returns high upon successful restart.
What input and output capacitors are mandatory for EN55022 Class B compliance?
Per the reference design: 4.7 µF X7R ceramic at VIN, 22 µF ×2 X7R/X5R at VOUT (for 5 V/12 V), plus 10 µF + 100 µF electrolytic for 12 V, and a 30 Ω @ 100 MHz ferrite bead (FB1) in series with VIN. Omitting any violates conducted/radiated EMI limits.
