Analog Devices Inc. ADP1031CP-4-EVALZ

Overview

ADP1031CP-4-EVALZ from Analog Devices is an evaluation board for the ADP1031 three-channel isolated micropower management unit with seven digital isolators. It provides fixed 24 V (VOUT1), 5.15 V (VOUT2), and adjustable −15 V (VOUT3) outputs, supports input voltages from 4.5 V to 60 V, and enables full functional validation of power regulation, oscillator synchronization, slew rate control, and isolated data channel operation in industrial field-powered systems.

For engineers reviewing the ADP1031CP-4-EVALZ datasheet, ADP1031CP-4-EVALZ pinout, ADP1031CP-4-EVALZ application, or ADP1031CP-4-EVALZ equivalent, this board delivers hands-on verification of line/load regulation, efficiency, power-good signaling, SPI-isolated communication, and high-voltage isolation barrier performance under real-world test conditions.

Technical Context

The ADP1031CP-4-EVALZ implements a complete reference design for the ADP1031ACPZ-4 IC, integrating a flyback regulator (24 V output), buck regulator (5.15 V fixed), and inverting regulator (−15 V adjustable), all galvanically isolated via integrated capacitive digital isolators. It exposes all seven isolated data channels-including SPI master/slave interfaces and GPIOs-through standardized headers (P1, P4).

Hardware features include jumper-configurable enable logic (P6), slew rate selection (P5), SYNC pin access for external clock synchronization (350–750 kHz), and test points for VOUT1/2/3, SWP, PGNDP, and SGND domains. The board supports up to 60 V differential voltage between VOUT1 and VOUT3 terminals when reconfigured per safety guidelines.

FAQ

What is the primary function of the ADP1031CP-4-EVALZ?

The ADP1031CP-4-EVALZ is an evaluation board for the ADP1031ACPZ-4 IC, enabling comprehensive testing of its three isolated DC/DC regulators (24 V, 5.15 V, −15 V) and seven-channel digital isolator. It allows engineers to validate line/load regulation, efficiency, sequencing, slew rate control, and isolated SPI/GPIO functionality without designing custom hardware. The ADP1031CP-4-EVALZ supports direct measurement of all key performance parameters defined in the ADP1031 data sheet.

How does the ADP1031CP-4-EVALZ differ from other models in the ADP1031CP-EVALZ series?

The ADP1031CP-4-EVALZ is uniquely configured with a fixed 24 V VOUT1, fixed 5.15 V VOUT2, and adjustable −15 V VOUT3 output. Unlike ADP1031CP-1/2/3-EVALZ, it omits R9 and R10 resistors used for VOUT3 fine-tuning, simplifying the −15 V adjustment path. It shares the same PCB layout and connector set as other variants but differs in factory-set feedback networks and default jumper states for EN and SLEW functions.

Can the ADP1031CP-4-EVALZ be used to evaluate the ADP1031ACPZ-5 device?

No - the ADP1031CP-4-EVALZ is specifically optimized for the ADP1031ACPZ-4 variant and its associated output configuration (24 V / 5.15 V / −15 V). While the board's hardware is physically compatible with ADP1031ACPZ-5, that device requires 21 V VOUT1, which is not supported by the ADP1031CP-4-EVALZ's fixed feedback network. Evaluation of ADP1031ACPZ-5 requires the ADP1031CP-5-EVALZ board.

What equipment is required to perform basic efficiency measurements on the ADP1031CP-4-EVALZ?

To measure overall efficiency on the ADP1031CP-4-EVALZ, you need a programmable DC power supply (4.5–60 V), two digital multimeters (for input/output voltage), one ammeter (or multimeter in series mode), electronic loads or precision resistors for VOUT1/2/3, and optionally an oscilloscope for dynamic response. Figure 7 in UG-1226 shows the exact connection setup, including test points TP10 (VINP), TP3 (PGNDP), TP7–TP9 (outputs), and proper grounding to SGND1/SGND2 planes.

Does the ADP1031CP-4-EVALZ support high-voltage isolation testing?

The ADP1031CP-4-EVALZ provides physical access to isolated domains (MVDD/PGNDP vs. SVDD/SGND) and supports up to 60 V differential voltage between VOUT1 and VOUT3 terminals when user-modified per safety instructions. However, the PCB itself is not hipot-tested or safety-certified; users must implement external insulation, spacing, and guarding per IEC 61000-4-5 or similar standards when performing high-voltage stress tests. No isolation barrier rating (e.g., 2.5 kVRMS) is guaranteed by the board alone.
