Product details
Overview
ADP5070RE-EVALZ from Analog Devices is a TSSOP evaluation board designed to characterize the ADP5070 dual-output DC-to-DC switching regulator, supporting ±15 V output from 3 V to 13.2 V input, delivering up to 480 mA (VPOS) and 140 mA (VNEG), with optional ADP7142/ADP7182 LDOs for low-noise ±12 V outputs. It enables line/load regulation, efficiency, soft start, sequencing, and slew rate testing in power supply design validation.
For engineers reviewing the ADP5070RE-EVALZ datasheet, ADP5070RE-EVALZ pinout, ADP5070RE-EVALZ application, or ADP5070RE-EVALZ equivalent, this board supports hands-on evaluation of dual-rail voltage generation, frequency selection (1.2 MHz / 2.4 MHz), precision enable control (EN1/EN2), startup sequencing (SEQ), and noise-sensitive LDO integration in industrial and instrumentation power systems.
Technical Context
The ADP5070RE-EVALZ implements a synchronous boost converter (VPOS) and an inverting buck-boost converter (VNEG) on a single PCB, using the ADP5070AREZ IC in 20-lead TSSOP package. It includes configurable compensation networks (JP5/JP6), external SYNC/FREQ and SEQ headers, and independent soft start (SS) and slew rate (SLEW) controls.
Board-level features include dual precision enable inputs (EN1/EN2), clamped V_EN header for >5.5 V input operation, LP_VIN/LN_VIN jumpers to route outputs to optional ADP7142 (+12 V) and ADP7182 (−12 V) LDO regulators, and test points for FB1/FB2, COMP1/COMP2, and SW1/SW2 nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 13.2 V - supports wide-input industrial and battery-powered systems without external pre-regulation. |
| Output Voltage (Default) | ±15 V - fixed dual-rail output configured via RFT1/RFB1 and RFT2/RFB2 feedback dividers. |
| VPOS Output Current | Up to 480 mA - sufficient for powering op-amp rails, ADC/DAC analog sections, or sensor signal chains. |
| VNEG Output Current | Up to 140 mA - enables symmetric negative biasing for precision analog front-ends. |
| Switching Frequency | Selectable 1.2 MHz or 2.4 MHz - allows trade-off between component size (higher fSW → smaller inductors) and efficiency/noise. |
| LDO Integration | Optional ADP7142 (+12 V) and ADP7182 (−12 V) - reduces output ripple and noise for sensitive analog loads. |
| Enable Control | Dual independent EN1/EN2 pins with internal pulldowns - supports flexible power-up sequencing and fault isolation. |

FAQ
What is the primary function of the ADP5070RE-EVALZ?
The ADP5070RE-EVALZ is an evaluation board for the ADP5070 dual-output DC-to-DC converter, enabling engineers to validate performance metrics including line/load regulation, efficiency, soft start behavior, sequencing, and noise reduction using optional LDOs. It is not a production power module but a characterization tool for design-in verification of the ADP5070AREZ IC.
Does the ADP5070RE-EVALZ support both positive and negative output regulation simultaneously?
Yes, the ADP5070RE-EVALZ supports simultaneous positive (VPOS) and negative (VNEG) output regulation using the integrated ADP5070AREZ IC. The board provides dedicated EN1 and EN2 headers, SEQ configuration options (simultaneous, sequenced, or manual startup), and independent feedback networks to verify coordinated dual-rail operation under varying load and input conditions.
Can the ADP5070RE-EVALZ generate outputs other than ±15 V?
Yes, the ADP5070RE-EVALZ can be reconfigured for alternative output voltages by modifying the feedback resistor dividers (RFT1/RFB1 for VPOS; RFT2/RFB2 for VNEG), as detailed in the ADP5070 data sheet and ADIsimPower tools. Default configuration delivers ±15 V, but custom designs may achieve outputs up to ±70 V differential depending on component selection and safety precautions.
How does the ADP5070RE-EVALZ integrate LDO regulators?
The ADP5070RE-EVALZ includes footprints and jumpers (LP_VIN, LN_VIN, J_LP_EN, J_LN_EN) to connect the ADP5070's VPOS and VNEG outputs to the ADP7142 (+12 V) and ADP7182 (−12 V) LDO regulators. When enabled, these LDOs provide low-noise, post-regulated outputs-critical for noise-sensitive analog circuits such as high-resolution ADCs or precision op-amps.
What external equipment is required to operate the ADP5070RE-EVALZ?
To operate the ADP5070RE-EVALZ, users need a DC power supply (3 V–13.2 V), multimeters for voltage/current measurements, and electronic or resistive loads. For efficiency testing, an external enable source (≤5.5 V), remote-sense power supply, and synchronized input/output ammeters/voltmeters are recommended to minimize measurement error from PCB trace impedance and switching ripple.
