ADP5075CB-EVALZ User Guide
User guide for the ADP5075CB-EVALZ evaluation board, a DC-to-DC inverting regulator providing -5 V at 190 mA from a 3 V to 5.5 V input.
Overview
This document provides instructions for evaluating the ADP5075 inverting DC-to-DC converter using the ADP5075CB-EVALZ evaluation board. The board is designed for a compact 6 mm x 5 mm layout and comes configured to deliver a -5 V output from a 3 V to 5.5 V input range. Key features documented include selectable switching frequencies of 1.2 MHz or 2.4 MHz, programmable soft start, and adjustable slew rate control for EMI management. The guide includes hardware setup procedures, performance measurements for line and load regulation, efficiency data, circuit schematics, and a detailed bill of materials.
Use Cases
- Line and load regulation testing
- Efficiency measurement and analysis
- EMI performance optimization via slew rate control
- Generating negative power rails for analog circuits
- Switching frequency synchronization testing
