Evaluation Board for the ADP5033 Micro PMU
User guide for the Analog Devices ADP5033 evaluation board, featuring two 3MHz buck regulators and two LDOs with power save mode (PSM) for high efficiency.
Overview
The UG-279 User Guide describes the evaluation board for the ADP5033 Micro Power Management Unit (PMU). The ADP5033 integrates two high-speed, current-mode buck regulators and two low-dropout (LDO) regulators designed for portable applications. The buck regulators operate at a 3 MHz switching frequency and feature a Power Save Mode (PSM) to improve efficiency during light load conditions. The evaluation board provides a standalone platform to measure performance metrics including line and load regulation, output ripple, efficiency, and ground current. The document includes detailed setup procedures, operating instructions, circuit schematics, PCB layout artwork, and a complete bill of materials.
Use Cases
- Evaluating the ADP5033 Micro PMU performance
- Prototyping power management systems for portable devices
- Measuring efficiency and regulation of integrated buck and LDO regulators
- Testing battery-powered device power schemes
