Product details
Overview
ADP1032ACPZ-3-R7 from Analog Devices is a two-channel isolated micropower management unit (PMU) integrating an isolated flyback regulator (VOUT1 = 3.3 V), a buck regulator (VOUT2 = 3.3 V), and seven digital isolators - four high-speed SPI channels and three general-purpose isolators. It operates from 4.5 V to 60 V input, delivers up to 2.5 W total isolated output power, and supports −40°C to +125°C junction temperature in industrial automation and data acquisition systems.
For engineers reviewing the ADP1032ACPZ-3-R7 datasheet, ADP1032ACPZ-3-R7 pinout, ADP1032ACPZ-3-R7 application, or ADP1032ACPZ-3-R7 equivalent, this device serves as a complete isolated power + signal interface solution for field-side sensor conditioning, PLC I/O modules, and safety-critical analog front-ends where galvanic separation, compact size (9 mm × 7 mm LFCSP), and regulatory compliance (UL 2500 V rms, VDE 565 VPEAK) are mandatory.
Technical Context
The ADP1032ACPZ-3-R7 implements dual independent regulation: a primary-side flyback controller with 440 mA switch current capability and adjustable 6 V–28 V output (configured as fixed 24 V in -3 variant), and a secondary-side buck regulator delivering factory-programmed 3.3 V at up to 50 mA. Both regulators use phase-shifted switching (250 kHz / 125 kHz default) to reduce EMI.
Its seven iCoupler® digital isolators include four SPI channels rated for 16.6 MHz clock rate and <12 ns propagation delay, plus three 100 kbps general-purpose GPIO isolators. All isolation domains - field power, master, and slave - maintain 300 V rms basic insulation per IEC 61010-1, with VIORM = 565 VPEAK and certified DIN V VDE 0884-10:2006-12 compliance pending.

Pinout & Package
ADP1032ACPZ-3-R7 uses a 41-lead, 9 mm × 7 mm lead-frame chip-scale package (LFCSP) with three exposed ground pads (EPGNDP, EPGNDM, EPGND2) internally connected to PGNDP, MGND, and SGND respectively. The package supports reflow soldering per JEDEC J-STD-020 and provides θJA = 50.4°C/W in natural convection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINP | Field power input | Main supply for flyback regulator; requires ≥3.3 µF bulk capacitance to PGNDP for stability and ripple suppression. |
| SWP | Flyback switch node | Connects to primary winding of 1:1 transformer; drives external clamp circuit (Zener/RCD) to manage leakage energy. |
| VOUT1 | Flyback output & sense | Delivers 24 V to slave domain; also feeds buck regulator input and provides overvoltage protection feedback path. |
| FB1 | Flyback feedback | Resistor-divider input referenced to SGND2; sets output voltage for adjustable variants (not used in ADP1032ACPZ-3-R7's fixed 24 V version). |
| VOUT2 | Buck output | Factory-set 3.3 V rail; supplies SVDD2, SGPO1/2, SGPI3, and other slave-side logic with ±1.5% accuracy over load/line/temperature. |
| SW2 | Buck switch node | Internal N/P-FET node connecting to external buck inductor; requires careful layout to minimize EMI and switching losses. |
| MCK, MO, MI, MSS, SCK, SO, SI | SPI isolator I/O | Four bidirectional SPI channels (MCK/MO/MI/MSS ↔ SCK/SO/SI/SSS); support full-duplex communication at ≤16.6 MHz with <125 ns latency. |
| MGPI1, MGPI2, MGPO3, SGPI3, SGPO1, SGPO2 | GPIO isolator I/O | Three unidirectional general-purpose isolators (MGPI1↔SGPO1, MGPI2↔SGPO2, MGPO3↔SGPI3); operate at ≤100 kbps with 14 µs propagation delay. |
| EN | Precision enable input | Logic-controlled startup with 1.135 V threshold and 100 mV hysteresis; allows system-level sequencing and fault shutdown. |
| PWRGD | Power-good indicator | Open-drain output asserting when both VOUT1 and VOUT2 are within ±10% tolerance; drives host MCU interrupt or reset logic. |
| SLEW | Flyback slew rate control | Selects SWP driver speed: open = fast (efficiency), VINP = normal, GNDP = slow (EMI reduction); no external components required. |
| SYNC | External frequency sync | Accepts 350–750 kHz clock to synchronize flyback (fSW = fSYNC/2) and buck (fSW = fSYNC/4) for noise-sensitive applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated power + signal interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADP1031ACPZ-3-R7 | Lower flyback switch current (300 mA vs. 440 mA); identical buck specs, same 7-isolator count, and identical 3.3 V VOUT2 programming. | Supports lower-power isolated loads (<1.8 W total); suitable for compact sensor nodes but not high-current analog front-ends. | Select ADP1031ACPZ-3-R7 only if total output current demand is ≤75 mA @ 24 V - avoids overdesign and reduces thermal stress. |
| ISO1211DWR | Dedicated 2-channel digital isolator (no power conversion); supports 50 Mbps data rate but lacks integrated regulators and GPIO functionality. | Requires external isolated DC/DC (e.g., RECOM RxxP2xx) for power; adds complexity and footprint for full-system isolation. | Choose ISO1211DWR only when existing isolated power rails exist and only high-speed serial isolation is needed - not a drop-in replacement. |
Compared with ADP1031ACPZ-3-R7, the ADP1032ACPZ-3-R7 delivers 47% higher flyback current capacity for driving larger isolated loads, while versus ISO1211DWR it integrates full power management - eliminating external converters, reducing bill-of-materials, and guaranteeing timing-aligned power and signal isolation.

FAQ
What output voltages does the ADP1032ACPZ-3-R7 provide, and how are they configured?
The ADP1032ACPZ-3-R7 provides two isolated outputs: VOUT1 is a fixed 24 V flyback output, and VOUT2 is a factory-programmed 3.3 V buck output. Unlike adjustable variants (e.g., ADP1032ACPZ-1), the -3 version has no FB1 resistor network dependency - VOUT2 accuracy is laser-trimmed to ±1.5% over temperature and load, and VOUT1 is internally set to 24 V without external feedback components.
How many digital isolators does the ADP1032ACPZ-3-R7 integrate, and what are their key timing specifications?
The ADP1032ACPZ-3-R7 integrates seven digital isolators: four high-speed SPI channels (MCK/MO/MI/MSS ↔ SCK/SO/SI/SSS) and three general-purpose GPIO channels (MGPI1/2/MGPO3 ↔ SGPO1/2/SGPI3). SPI channels support up to 16.6 MHz clock rates with 7–12 ns propagation delay and <6.5 ns pulse-width distortion; GPIO channels operate at ≤100 kbps with 14 µs propagation delay and 19.5 µs jitter.
What safety certifications apply to the ADP1032ACPZ-3-R7, and what do they mean for system design?
The ADP1032ACPZ-3-R7 carries pending UL recognition (2500 V rms, 1 minute), CSA Component Acceptance Notice 5A, and VDE certification per DIN V VDE 0884-10:2006-12 with VIORM = 565 VPEAK. These ratings validate its suitability for reinforced insulation in IEC 61010-1-compliant equipment, allowing designers to meet system-level safety requirements without additional barrier reinforcement or creepage extension.
Can the ADP1032ACPZ-3-R7 synchronize its switching frequency to an external clock, and why is this useful?
Yes, the ADP1032ACPZ-3-R7 accepts an external SYNC signal (350–750 kHz) on Pin 14 to lock flyback (fSW = fSYNC/2) and buck (fSW = fSYNC/4) frequencies. This capability enables EMI filtering in noise-sensitive applications such as medical instrumentation or precision metrology, where deterministic switching harmonics can be targeted and suppressed using narrowband filters.
What thermal considerations apply to the ADP1032ACPZ-3-R7 in high-ambient environments?
The ADP1032ACPZ-3-R7 features internal thermal shutdown at 150°C and a documented θJA of 50.4°C/W. In ambient temperatures above 85°C, designers must verify junction temperature using ΨJT = 25°C/W and measured case temperature near Pin 1; thermal vias under EPGNDP/EPGNDM/EPGND2 and copper pour on inner layers are essential to maintain TJ < 125°C at full 2.5 W load.
