Monolithic Power Systems (MPS) EVBL4423H-Q-00A Evaluation Board
Monolithic Power Systems (MPS) EVBL4423H-Q-00A Evaluation Board is designed to evaluate the MP4423H and MPQ4423H switching voltage regulators. These regulators are high-frequency, synchronous, rectified, and step-down switch-mode converters with built-in power MOSFETs and an integrated MPS power inductor. The MP4423H/MPQ4423H regulators have synchronous mode and current mode operation. The synchronous mode provides high efficiency across the entire IOUT range and a current mode that provides fast transient response and eases loop stabilization.
The EVBL4423H-Q-00A evaluation board is a fully assembled and tested board that operates from 4V to 36V input voltage (VIN) range. This evaluation board is AEC-Q100 Grade 1 qualified for use in automotive, industrial control, and distributed power systems.
