Analog Devices Inc. ADP5070CP-EVALZ

Overview

ADP5070CP-EVALZ from Analog Devices is an evaluation board for the ADP5070 dual DC-to-DC switching regulator IC, designed to generate independently adjustable positive (up to +39 V) and negative (down to VIN − 39 V) output rails from a 2.85 V to 15 V input. It supports 1.2 MHz/2.4 MHz switching, slew rate control, precision enable sequencing, and true shutdown - enabling rapid prototyping of bipolar power supplies for precision analog systems.

For engineers reviewing the ADP5070CP-EVALZ datasheet, ADP5070CP-EVALZ setup guide, ADP5070CP-EVALZ test configuration, or ADP5070CP-EVALZ alternative evaluation platforms, this board provides validated reference design, full pin access to all ADP5070 signals (including SYNC/FREQ, SEQ, SLEW, EN1/EN2, FB1/FB2), and compatibility with standard bench equipment for dynamic load transient, efficiency, and cross-regulation analysis.

Technical Context

The ADP5070CP-EVALZ implements the full ADP5070 functional architecture: a 1.0 A boost regulator and 0.6 A inverting regulator operating out-of-phase at selectable 1.2 MHz or 2.4 MHz, with external synchronization support from 1.0 MHz to 2.6 MHz. It exposes all critical compensation nodes (COMP1/COMP2), soft-start (SS), sequence control (SEQ), and slew-rate configuration (SLEW) pins for loop tuning and noise optimization.

Board-level features include populated high-efficiency external components (L1/L2 inductors, D1/D2 Schottky diodes, CIN/COUT capacitors), test points for SW1/SW2 switching nodes and FB1/FB2 feedback paths, and jumper-selectable EN1/EN2 logic levels and SEQ modes (VPOS-first, VNEG-first, simultaneous). The layout follows Analog Devices' recommended 4-layer PCB stack-up with thermal vias under the LFCSP exposed pad.

FAQ

What is the primary function of the ADP5070CP-EVALZ?

The ADP5070CP-EVALZ is an evaluation board for the ADP5070 dual switching regulator IC. It enables engineers to validate the ADP5070's independent positive and negative output generation, sequencing control, slew rate adjustment, and synchronization capabilities using real-world component values and measurement points. The board is preconfigured to demonstrate full ADP5070 functionality without requiring custom layout or component selection.

Does the ADP5070CP-EVALZ support both LFCSP and TSSOP packages of the ADP5070?

No - the ADP5070CP-EVALZ is designed exclusively for the 20-lead LFCSP package of the ADP5070, as confirmed by its footprint, thermal pad connection, and pinout alignment with Figure 2 of the ADP5070 Rev. E datasheet. It does not accommodate the 20-lead TSSOP variant due to mechanical and thermal layout differences.

Can the ADP5070CP-EVALZ be used to evaluate SEPIC operation mode?

Yes - the ADP5070CP-EVALZ supports optional SEPIC configuration for the boost regulator, as specified in the ADP5070 datasheet. The board includes provisioned pads and jumpers to reconfigure the input stage per Figure 25 of the datasheet, enabling step-up/step-down operation while maintaining regulated VPOS and VNEG outputs.

What are the key test points accessible on the ADP5070CP-EVALZ?

The ADP5070CP-EVALZ provides dedicated test points for SW1 and SW2 switching nodes, FB1 and FB2 feedback inputs, COMP1 and COMP2 compensation networks, EN1 and EN2 enable inputs, SEQ and SLEW configuration pins, and all power inputs (PVIN1, PVIN2, PVINSYS) and grounds (AGND, PGND). These allow direct oscilloscope probing for transient response, loop stability, and regulation accuracy measurements.

Is the ADP5070CP-EVALZ compatible with ADIsimPower design tools?

Yes - the ADP5070CP-EVALZ is fully supported by Analog Devices' ADIsimPower toolset. Users can import the board's default component values (inductors L1/L2, output capacitors, feedback resistors) into ADIsimPower to simulate efficiency, ripple, thermal performance, and loop response before hardware testing, ensuring correlation between simulation and ADP5070CP-EVALZ measured results.
