Analog Devices Inc. ADP5071RE-EVALZ

Overview

ADP5071RE-EVALZ from Analog Devices is a TSSOP evaluation board designed to characterize the ADP5071 dual-output DC-to-DC switching regulator, supporting ±15 V output at up to 1020 mA (VPOS) and 320 mA (VNEG) across a 3 V to 13.2 V input range. It integrates configurable soft start, slew rate control, sequencing, and optional ADP7142/ADP7182 LDO regulators for low-noise ±12 V outputs.

For engineers reviewing the ADP5071RE-EVALZ datasheet, ADP5071RE-EVALZ pinout, ADP5071RE-EVALZ application, or ADP5071RE-EVALZ equivalent, this board enables precise measurement of line regulation, load regulation, efficiency, and transient response - critical for bipolar power supply validation in precision analog, medical instrumentation, and industrial sensor systems.

Technical Context

The ADP5071RE-EVALZ implements a synchronous boost + inverting topology with independent enable (EN1/EN2), frequency selection (1.2 MHz / 2.4 MHz via SYNC/FREQ), and startup sequencing (SEQ pin). It supports external clock synchronization and user-configurable compensation networks (Type 2/3) for stability optimization across varying loads and input conditions.

On-board LDO options include the ADP7142 (positive, 12 V, 200 mA) and ADP7182 (negative, −12 V, 200 mA), each with dedicated enable (LP_EN/LN_EN), noise reduction (CNR3/CNR4), and soft-start (CSS3) provisions. All control signals - SLEW, SS, SEQ - are accessible via solder jumpers or headers for real-time configuration without rework.

FAQ

What is the primary function of the ADP5071RE-EVALZ?

The ADP5071RE-EVALZ is an evaluation board for the ADP5071 dual-output switching regulator IC. It provides a fully assembled, test-ready platform to evaluate the ADP5071's ±15 V generation, efficiency, regulation performance, and advanced features including sequencing, soft start, and slew rate control - all without custom PCB design.

Does the ADP5071RE-EVALZ support both boost and inverting topologies simultaneously?

Yes, the ADP5071RE-EVALZ demonstrates the ADP5071's integrated dual-converter architecture: a synchronous boost regulator generating +15 V (VPOS) and an inverting regulator generating −15 V (VNEG), both operating concurrently from a single 3 V–13.2 V input source.

Can the ADP5071RE-EVALZ be used to validate LDO post-regulation?

Yes, the ADP5071RE-EVALZ includes footprints and routing for the ADP7142 (positive) and ADP7182 (negative) LDOs, configured by default to deliver ±12 V with low noise and high PSRR - enabling direct comparison of switched vs. regulated output quality under identical load conditions.

How is switching frequency selected on the ADP5071RE-EVALZ?

Switching frequency on the ADP5071RE-EVALZ is set via the SYNC/FREQ header: pulling the center pin high selects 2.4 MHz, pulling it low selects 1.2 MHz, and connecting an external clock (≤5.5 V) enables synchronization - allowing EMI-sensitive designs to align switching with system clocks.

What safety or operational limits apply when modifying the ADP5071RE-EVALZ?

Per the UG-848 user guide, customized configurations may achieve >70 V differential between POS and NEG terminals and >1 A boost output, but users must verify thermal integrity, voltage ratings of installed components (e.g., capacitors, diodes), and isolation compliance - Analog Devices explicitly disclaims liability for modifications beyond default configurations.
