Product details
Overview
MID06W0503AGY-2S-Z from Monolithic Power Systems is a semi-regulated, isolated DC/DC converter delivering 3.3V/180mA (0.6W) output from a 4.5–5.5V input, with 1.5kVDC isolation, SOICW-16 package, and operation across –40°C to +125°C. It integrates power MOSFET, transformer, and feedback circuitry, enabling compact isolated bias for digital isolators and RS-485/CAN interfaces.
For engineers reviewing the MID06W0503AGY-2S-Z datasheet, MID06W0503AGY-2S-Z pinout, MID06W0503AGY-2S-Z application, or MID06W0503AGY-2S-Z equivalent, key selection criteria include isolation voltage rating (1.5kVDC), semi-regulated 3.3V output accuracy (±0.4% typical), load regulation (0.4%), line regulation (0.2%), and thermal shutdown at 160°C.
Technical Context
The device implements transformer-coupled flyback topology with integrated primary-side switching and secondary-side feedback via internal optocoupler-equivalent encoding/decoding. Regulation is achieved through cycle-by-cycle current limiting and duty-cycle modulation based on isolated feedback signals.
It features non-latching under-voltage lockout (UVLO rising threshold 2.61V), hiccup-mode short-circuit protection (150ms off-time), and thermal shutdown with 20°C hysteresis (160°C trip, 140°C recovery). EMI compliance is achieved via internal soft-start (15ms), optimized PCB layout guidance, and CLC filter support.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 5.5V - supports standard 5V rail with ±10% tolerance; UVLO prevents operation below 2.61V. |
| Output Voltage | 3.3V ±0.4% (typical) - semi-regulated accuracy sufficient for digital isolator bias and interface ICs without post-regulation. |
| Output Power | 0.6W (3.3V @ 180mA) - enables isolated supply for multiple low-power peripherals in industrial gateways. |
| Isolation Voltage | 1.5kVDC (60s test) - meets reinforced insulation requirements for industrial I/O and telecom equipment per IEC62368-1. |
| Efficiency | 38% at full load - typical for ultra-compact isolated converters; optimized for space-constrained designs over peak efficiency. |
| Load Regulation | 0.4% - ensures stable VOUT across 0–180mA load range, critical for consistent logic-level translation in isolated interfaces. |
| Thermal Shutdown | 160°C with 20°C hysteresis - protects against sustained overload or poor heatsinking in sealed enclosures. |
Pinout & Package
Package: SOICW-16 (wide-body, 10.3mm × 7.5mm × 2.3mm), MSL Level 3, RoHS-compliant, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 PGND1 | Primary-side power ground | Must connect with large copper traces and multiple vias to minimize thermal resistance and improve heat dissipation. |
| 3, 4 VIN | Input power supply | Accepts 4.5–5.5V; requires local 10μF + 0.1μF decoupling to PGND1 for stability and noise suppression. |
| 5–8 SGND1 | Primary-side signal ground | Connected to PGND1 with wide copper to reduce ground bounce; forms reference for control circuitry. |
| 9–12 SGND2 | Secondary-side signal ground | Must connect to PGND2 via thin trace only - prevents EMI coupling into isolated output domain. |
| 13, 14 VOUT | Isolated 3.3V output | Delivers regulated power; requires 10μF + 0.1μF decoupling to PGND2 to limit ripple (<100mV p-p). |
| 15, 16 PGND2 | Secondary-side power ground | Isolated from PGND1; avoid large copper areas to suppress radiated emissions per CISPR32 Class B. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated transformer & MOSFET | Eliminates external magnetics and high-side switch, reducing BOM count and board area by >40% vs discrete solutions. |
| 1.5kVDC isolation | Enables safe galvanic separation between microcontroller domains and field-side buses (e.g., RS-485, CAN) in harsh environments. |
| Hiccup-mode SCP | Prevents thermal runaway during sustained short circuits by cycling 15ms soft-start + 150ms off-time until fault clears. |
| CISPR32 Class B compliance | Validated radiated emissions <40dBuV/m at 3m distance - allows direct use in commercial-grade industrial gateways without shielding. |
| –40°C to +125°C operation | Rated junction temperature range supports deployment in uncooled enclosures near motors, power supplies, or outdoor telecom units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated DC/DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RECOM RxxPxx Series (e.g., R1SX-0503-R) | Unregulated output (±10%); larger DIP-7 package; no integrated feedback; lower efficiency (~30%) | Lacks load/line regulation - requires external LDO for precision rails; unsuitable for tight-tolerance digital isolators | Select only when cost sensitivity outweighs regulation performance and board space constraints. |
| Analog Devices ADUM6000 | Fully regulated 3.3V output (±1.5%); higher efficiency (45%); 2.5kVrms isolation; requires external transformer | Supports tighter VOUT tolerance but adds design complexity and component count; larger solution size | Choose when downstream circuitry demands strict voltage accuracy and higher reliability over integration simplicity. |
Compared with RECOM R1SX-0503-R and ADUM6000, MID06W0503AGY-2S-Z delivers optimal balance of integration (single-chip), regulation accuracy (0.4%), and compactness (SOICW-16), making it ideal for space-constrained industrial interfaces where semi-regulation suffices.

FAQ
What is the maximum capacitive load the MID06W0503AGY-2S-Z can drive?
The device supports up to 330µF capacitive load when paired with a 45Ω resistive load, as verified in production testing. Exceeding this value may trigger hiccup-mode protection during startup due to excessive inrush current. For loads >100µF, ensure adequate soft-start margin and verify transient response on the target PCB layout.
Does MID06W0503AGY-2S-Z require external feedback components?
No. The device integrates all feedback circuitry-including isolation encoding/decoding-within the SOICW-16 package. No external optocouplers, resistors, or compensation networks are needed. Only input and output decoupling capacitors (10µF + 0.1µF each) are required for stable operation.
How does the 1.5kVDC isolation rating impact PCB layout requirements?
The 1.5kVDC rating mandates ≥8mm creepage and clearance between primary (pins 1–8) and secondary (pins 9–16) sides. This requires physical separation of GND1 and GND2 copper pours, slotting under the IC body, and adherence to IPC-2221B spacing rules-verified in the recommended land pattern and Figure 3 layout guide.
Can MID06W0503AGY-2S-Z operate at 4.5V input with full 180mA load at 125°C?
Yes, but output voltage accuracy degrades to ±5% under these corner conditions (4.5V, 180mA, TA = 80°C+). For applications requiring tighter regulation, operate above 4.75V input or add an LDO post-regulator. The device remains functional and protected via OTP and SCP throughout this range.
What certifications does MID06W0503AGY-2S-Z hold?
It is UL1577 certified (reinforced insulation), CB certified to IEC62368-1 3rd Edition, and meets CISPR32 Class B radiated emissions limits. These certifications validate its suitability for commercial and industrial end-equipment without additional system-level isolation testing.
Is there a pin-compatible 3kVDC version?
Yes - MID06W0503AGY-3S-Z uses identical SOICW-16 packaging and pinout but provides 3kVDC isolation. Both share the same top marking prefix (06W0503A2 vs 06W0503A3) and thermal characteristics; only isolation test voltage and qualification differ.
