Product details
Overview
MID06W0503AGY-2S-P 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, featuring 1.5kVDC isolation, SOICW-16 packaging, and integrated power MOSFET, transformer, and feedback circuitry - deployed in isolated bias supplies for RS-485, CAN, and digital isolators.
For engineers reviewing the MID06W0503AGY-2S-P datasheet, MID06W0503AGY-2S-P pinout, MID06W0503AGY-2S-P application, or MID06W0503AGY-2S-P equivalent, key selection criteria include input voltage range (4.5–5.5V), isolation rating (1.5kVDC), thermal shutdown threshold (160°C), load regulation (0.4%), and SOICW-16 footprint compatibility with industrial PCB layouts.
Technical Context
The device implements a monolithic flyback topology with internal primary-side switching and transformer-coupled secondary-side regulation via integrated feedback circuitry. It operates without external optocouplers or secondary-side controllers, relying on transformer turns ratio and internal hysteresis to achieve semi-regulated output stability.
Protection architecture includes non-latching under-voltage lockout (UVLO rising threshold 2.61V), hiccup-mode short-circuit protection (150ms off-time), over-temperature shutdown (160°C trip, 140°C recovery), and built-in soft-start (15ms ramp). EMI compliance is achieved via optimized PCB layout guidance and CLC filtering recommendations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 5.5V - supports standard 5V rail systems with ±10% tolerance; UVLO prevents operation below 2.61V. |
| Output Voltage | 3.3V ±0.05V at 25°C, ±0.07V over -40°C to +125°C - sufficient for biasing digital isolators and transceivers without post-regulation. |
| Isolation Voltage | 1.5kVDC (MID06W0503AGY-2S-P) - meets reinforced insulation requirements for industrial I/O and communication interfaces per IEC62368-1. |
| Output Power | 0.6W (3.3V @ 180mA) - enables compact isolated supply for low-power signal-chain peripherals without heatsinking. |
| Load Regulation | 0.4% (0–180mA) - ensures stable VOUT across full load range, critical for precision analog front-ends and sensor excitation. |
| Line Regulation | 0.2% (4.5–5.5V input) - minimizes output drift during input rail variation, supporting robust operation in noisy 5V domains. |
| Efficiency | 38% at full load - optimized for low-power isolation where size and reliability outweigh peak efficiency concerns. |
| Thermal Shutdown | 160°C junction temperature - protects against sustained overload or poor PCB thermal design; recovers at 140°C. |
Pinout & Package
Available in a low-profile, wide-body SOICW-16 package (10.3mm × 10.3mm × 2.65mm) with creepage/clearance ≥8mm, qualified per JEDEC MS-013 AA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | PGND1 | Primary-side power ground - requires large copper area and multiple vias for thermal dissipation and noise control. |
| 3, 4 | VIN | 4.5–5.5V input - must be decoupled with 10μF + 0.1μF capacitors placed adjacent to pins 3/4 and PGND1. |
| 5–8 | SGND1 | Primary-side signal ground - tied to PGND1 with wide traces to minimize ground bounce in control circuitry. |
| 9–12 | SGND2 | Secondary-side signal ground - connected to PGND2 via thin trace only to suppress EMI coupling. |
| 13, 14 | VOUT | 3.3V isolated output - decoupled with 10μF + 0.1μF capacitors between pins 13/14 and PGND2 to reduce ripple (<100mV). |
| 15, 16 | PGND2 | Secondary-side power ground - kept isolated from SGND2 with minimal copper to avoid radiated emissions. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated transformer & MOSFET | Eliminates discrete magnetics and gate-drive complexity - reduces BOM count and layout area by >40% vs. discrete flyback designs. |
| Hiccup-mode SCP | Self-recovering fault response with 150ms off-time - avoids latch-up during intermittent shorts while preserving downstream circuit integrity. |
| CISPR32 Class B compliance | Validated radiated emissions <40dBuV/m at 3m - enables direct use in industrial gateways and 5G RRUs without additional shielding. |
| UL1577 & CB IEC62368-1 certified | Reinforced isolation safety approval - satisfies regulatory requirements for functional isolation in PLC I/O modules and motor drives. |
| -40°C to +125°C operation | Rated junction temperature range - supports deployment in uncooled enclosures for factory automation and outdoor telecom equipment. |

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% VOUT tolerance), 1W output, DIP-8 package, no integrated feedback. | Lacks load/line regulation - requires external LDO or Zener clamp for precision loads; larger footprint. | Select when cost sensitivity outweighs regulation accuracy and board space is not constrained. |
| Analog Devices ADuM6000 | Full regulation (±1% VOUT), 0.5W, 5kVrms isolation, SOIC-16, but requires external transformer and feedback components. | Higher isolation and tighter regulation, but increases design complexity and BOM count by 7+ passive parts. | Select when system-level safety certification demands >3kVDC isolation and sub-2% output accuracy is mandatory. |
Compared with RECOM R1SX-0503-R and ADuM6000, the MID06W0503AGY-2S-P delivers optimal balance of integration (monolithic transformer/MOSFET/FB), 1.5kVDC safety compliance, and 0.4% load regulation - reducing design risk and time-to-market for industrial I/O and communications modules.

FAQ
What is the maximum continuous output current of the MID06W0503AGY-2S-P?
The device delivers up to 180mA continuously at 3.3V (0.6W), verified across -40°C to +125°C ambient with proper PCB thermal design. Derating applies above 85°C ambient due to thermal shutdown activation at 160°C junction temperature.
Does the MID06W0503AGY-2S-P require external feedback components?
No - it integrates all feedback circuitry, transformer, and power MOSFET in a single SOICW-16 package. Only two external 10μF input/output capacitors and two 0.1μF ceramic capacitors are required for stable operation per the typical application circuit.
Can the MID06W0503AGY-2S-P be used with a 3.3V input supply?
No - its specified input range is strictly 4.5V to 5.5V. Operation below 4.5V violates absolute maximum ratings and triggers under-voltage lockout; the UVLO rising threshold is 2.61V, but functional operation begins only above 4.5V VIN.
How does the hiccup-mode short-circuit protection behave during fault conditions?
Upon detecting sustained short-circuit or excessive capacitive load, the device enters hiccup mode: it disables switching for ~150ms, then attempts soft-start again. This cycle repeats until the fault clears, limiting average power dissipation and preventing thermal damage.
What is the minimum recommended PCB copper area for PGND1 and PGND2?
PGND1 requires ≥200mm² copper area with ≥4 thermal vias (0.3mm diameter) to maintain junction temperature below 125°C at full load. PGND2 must use minimal copper (≤10mm²) and thin traces to suppress EMI - per MPS layout guidelines in Figure 3.
Is the MID06W0503AGY-2S-P compliant with automotive AEC-Q200 standards?
No - it is rated for industrial temperature range (-40°C to +125°C) and certified to UL1577 and IEC62368-1, but lacks AEC-Q200 qualification. For automotive applications, MPS recommends the pin-compatible MID06W0503AGY-3S variant with 3kVDC isolation and extended validation.
What is the input-to-output capacitance (CI-O) and why does it matter?
CI-O is 7pF, measured between shorted primary pins (1–8) and shorted secondary pins (9–16) at 1MHz. This ultra-low value minimizes noise coupling across the isolation barrier - critical for maintaining signal integrity in high-speed digital isolator and ADC reference applications.
