Monolithic Power Systems (MPS) EVQ8633B-H-LE-00A Evaluation Board
Monolithic Power Systems (MPS) EVQ8633B-H-LE-00A Evaluation Board is designed for MPQ8633B-H, a high-efficiency, monolithic, and synchronous converter. This MPQ8633B-H utilizes an internally compensated Constant-On-Time (COT) control mode that provides a fast transient response and eases loop stabilization. The EVQ8633B-H-LE-00A evaluation board can be turned on or off via a remote on/off input (EN) referenced to the ground, and the information is compatible with popular logic devices. This EVQ8633B-H-LE-00A evaluation board features a proprietary switching loss reduction technique and adaptive COT control for ultra-fast transient response. The EVQ8633B-H-LE-00A evaluation board operates at -40°C to 125°C temperature range and 8V to 16V input voltage range. This evaluation board is ideally used in telecom and networking systems, servers, cloud computing, and storage base stations.
