Product details
Overview
ADP1032ACPZ-1-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 = 5.15 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 output power, and targets industrial field-side power and signal isolation in process control systems.
For engineers reviewing the ADP1032ACPZ-1-R7 datasheet, ADP1032ACPZ-1-R7 pinout, ADP1032ACPZ-1-R7 application, or ADP1032ACPZ-1-R7 equivalent, this page provides verified technical context, validated pin functions, confirmed isolation ratings (2500 V rms, VIORM = 565 VPEAK), real-world efficiency data (86.5% at full load), and precise alternative part comparisons for power + signal co-isolation designs.
Technical Context
The ADP1032ACPZ-1-R7 implements dual independent regulation: a primary-side controlled flyback (250 kHz nominal, 440 mA switch current limit) generating VOUT1 = 24 V, and a secondary-side synchronous buck (125 kHz nominal, 300 mA switch current limit) generating VOUT2 = 5.15 V. Both regulators feature internal compensation, soft-start timers (8 ms), and precision enable/power-good monitoring.
Its seven iCoupler® digital isolators are partitioned across three domains: master (MVDD), slave (SVDD1/SVDD2), and field power (VINP/PGNDP). Four high-speed channels (16.6 MHz SPI, 7–15 ns propagation delay) isolate SPI bus signals; three general-purpose channels (100 kbps, 14 µs propagation delay) support GPIO-level isolation with common-mode transient immunity of 100 kV/µs.

FAQ
What output voltages does the ADP1032ACPZ-1-R7 provide?
The ADP1032ACPZ-1-R7 provides two isolated output rails: VOUT1 is fixed at 24 V (±1.5% accuracy), and VOUT2 is factory-programmed to 5.15 V (±1.5% accuracy). These values are specific to the ADP1032ACPZ-1-R7 variant; other members of the ADP1032 family offer adjustable VOUT1 or 3.3 V/5.0 V VOUT2 options.
Does the ADP1032ACPZ-1-R7 require external transformers or magnetics?
Yes, the ADP1032ACPZ-1-R7 requires an external 1:1 turns ratio transformer for the flyback regulator (e.g., Coilcraft ZA9644-AE) and an external inductor for the buck regulator. The IC integrates all power switches, controllers, and feedback circuitry but relies on external passive components for energy transfer and filtering.
How is isolation achieved between the three domains in the ADP1032ACPZ-1-R7?
Isolation in the ADP1032ACPZ-1-R7 is implemented using Analog Devices' iCoupler® chip-scale transformer technology for all seven digital channels, and reinforced creepage/clearance (≥2.15 mm) plus 18 µm internal insulation for the power domains. Field power (VINP/PGNDP), master (MVDD/MGND), and slave (SVDD1/SVDD2/SGND1/SGND2) domains are physically and electrically separated per IEC 61010-1 and VDE 0884-10.
What is the purpose of the SLEW pin on the ADP1032ACPZ-1-R7?
The SLEW pin (Pin 32) configures the slew rate of the flyback switch node (SWP) driver. Leaving it open enables fastest slew (best efficiency), connecting it to VINP sets normal slew, and tying it to GNDP selects slowest slew (best EMI performance). This allows dynamic optimization without changing external components.
Can the ADP1032ACPZ-1-R7 be synchronized to an external clock?
Yes, the ADP1032ACPZ-1-R7 supports external synchronization via the SYNC pin (Pin 14). Applying a 350–750 kHz clock to SYNC forces the flyback regulator to operate at fSYNC/2 and the buck regulator at fSYNC/4, enabling precise EMI frequency placement and multi-device coherence in dense layouts.
