Product details
Overview
ADP1032ACPZ-2-R7 from Analog Devices is a two-channel isolated micropower management unit (PMU) integrating an isolated flyback regulator (VOUT1 = 24 V fixed), a buck regulator (VOUT2 = 5.0 V factory-programmed), and seven digital isolators (four SPI + three GPIO). It operates from 4.5 V to 60 V input, delivers up to 2.5 W total isolated power, and targets industrial process control systems requiring compact, safety-certified power + signal isolation.
For engineers reviewing the ADP1032ACPZ-2-R7 datasheet, ADP1032ACPZ-2-R7 pinout, ADP1032ACPZ-2-R7 application, or ADP1032ACPZ-2-R7 equivalent, this page provides verified technical context, validated pin functions, confirmed isolation specifications (565 VPEAK VIORM, UL 2500 Vrms), real-world efficiency data (86.5% typ. at full load), and precise alternative part guidance for dual-rail isolated PMU selection.
Technical Context
The ADP1032ACPZ-2-R7 implements phase-shifted dual regulation: flyback (250 kHz nominal, adjustable via SYNC) supplies VOUT1 = 24 V with integrated 440 mA switch and 3 Ω RON, while buck (125 kHz nominal) supplies VOUT2 = 5.0 V using separate NMOS/PMOS switches (RON = 1 Ω / 2.5 Ω). Both regulators feature precision enable, power-good monitoring, and soft-start timers (8 ms).
Its seven iCoupler® isolators are partitioned across domains: four high-speed SPI channels (16.6 MHz clock rate, 7–15 ns propagation delay) bridge master/slave interfaces, and three general-purpose GPIO channels (100 kbps, 14 µs propagation delay) support discrete I/O isolation. All isolators use chip-scale transformer technology with 100 kV/µs common-mode transient immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 60 V - supports wide industrial supply rails including 24 V DC and 48 V telecom systems. |

Pinout & Package
ADP1032ACPZ-2-R7 uses a 41-lead, 9 mm × 7 mm LFCSP package with three galvanically isolated domains: Field Power (VINP, SWP, PGNDP), Master (MVDD, MCK, MI), and Slave (SVDD1, SCK, VOUT2). Exposed pads (EPGNDP, EPGNDM, EPGND2) are internally connected to respective domain grounds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINP (Pin 30) | Field Power Input | Primary-side supply input; requires ≥3.3 µF bulk capacitance to PGNDP for stability. |
| SWP (Pin 29) | Flyback Switch Node | Connects to primary winding of 1:1 transformer; slew rate controlled by SLEW pin. |
| VOUT1 (Pin 18) | Flyback Output / Sense | 24 V regulated output; also serves as overvoltage sense input for flyback protection. |
| VOUT2 (Pin 15) | Buck Output | 5.0 V regulated output; powers slave-domain logic and isolator supplies (SVDD1/SVDD2). |
| MCK (Pin 40) | Master SPI Clock Input | Drives slave SCK; enables synchronous isolation of high-speed serial data streams. |
| MGPI1 (Pin 36) | Master GPIO Input | Paired with SGPO1; supports isolated status monitoring (e.g., fault signals from field side). |
| PWRGD (Pin 35) | Power-Good Output | Open-drain logic signal indicating both VOUT1 and VOUT2 are within ±10% tolerance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual-isolated power rails | Eliminates need for two discrete isolated DC/DC converters and external isolators - reduces BOM count and PCB area by >40%. |
| Phase-shifted switching (flyback + buck) | Reduces input ripple current and system-level EMI, easing compliance with CISPR 11 Class B emissions limits. |
| iCoupler® SPI isolation (4 channels) | Enables full-duplex isolated communication with <15 ns channel-to-channel skew - critical for time-sensitive control loops. |
| Factory-programmed VOUT2 | 5.0 V option (ADP1032ACPZ-2) removes post-manufacturing configuration steps - accelerates design-in and production ramp. |
| UL 2500 Vrms / VDE 0884-10 certified | Meets safety requirements for industrial equipment without additional external barrier components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated dual-rail power + signal isolation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADP1031ACPZ-R7 | Flyback switch rated 300 mA (vs. 440 mA); no buck regulator - single isolated rail only. | Cannot replace ADP1032ACPZ-2-R7 in dual-output designs; suitable only when VOUT2 is generated externally. | Select only if system requires only one isolated rail and lower power (≤1.5 W). |
| ISO1212DWR | Digital isolator-only device (6-channel); zero integrated power conversion capability. | Requires external isolated DC/DC converters for both VOUT1 and VOUT2 - increases component count and board space. | Choose when existing power architecture is fixed and only signal isolation is needed. |
Compared with ADP1031ACPZ-R7 and ISO1212DWR, the ADP1032ACPZ-2-R7 uniquely integrates dual isolated power rails with seven high-performance isolators in one package - reducing bill-of-materials, simplifying safety certification, and enabling compact, thermally efficient designs for industrial automation.

FAQ
What output voltages does the ADP1032ACPZ-2-R7 provide?
The ADP1032ACPZ-2-R7 provides two isolated outputs: VOUT1 is a fixed 24 V rail (±1.5% accuracy), and VOUT2 is factory-programmed to 5.0 V (also ±1.5%). These are independent, fully regulated rails derived from separate flyback and buck regulators - no external feedback components are needed for either output.
How many digital isolators are integrated into the ADP1032ACPZ-2-R7?
The ADP1032ACPZ-2-R7 integrates seven digital isolators: four high-speed SPI channels (MCK/MSS/MO/SI ↔ SCK/SSS/SO/MI) supporting up to 16.6 MHz, and three general-purpose GPIO channels (MGPI1/MGPI2/MGPO3 ↔ SGPO1/SGPO2/SGPI3) rated for 100 kbps. All use Analog Devices' iCoupler® transformer-based isolation technology.
What safety certifications apply to the ADP1032ACPZ-2-R7?
The ADP1032ACPZ-2-R7 carries pending certifications per UL 1577 (2500 Vrms isolation), CSA Component Acceptance Notice 5A, and DIN V VDE 0884-10 (VIORM = 565 VPEAK). It meets basic insulation requirements per IEC 61010-1 (300 Vrms) and supports CISPR 11 Class B radiated emissions compliance when implemented per layout guidelines.
Can the ADP1032ACPZ-2-R7 operate with an external clock source?
Yes - the ADP1032ACPZ-2-R7 supports external synchronization via its SYNC pin (Pin 14). Applying a 350 kHz to 750 kHz clock enables precise frequency control: flyback runs at fSYNC/2 and buck at fSYNC/4. This eases EMI filtering in noise-sensitive applications and allows synchronization with other system clocks.
What is the maximum total output power of the ADP1032ACPZ-2-R7?
The ADP1032ACPZ-2-R7 delivers up to 2.5 W total isolated output power under typical conditions (VOUT1 = 24 V @ 100 mA, VOUT2 = 3.3 V @ 30 mA, using Coilcraft ZA9644-AE transformer). Efficiency reaches 86.5% at full load, and thermal design supports continuous operation across −40°C to +125°C junction temperature.
