Monolithic Power Systems (MPS) EVBL4423A-Q-00A Evaluation Board

Monolithic Power Systems (MPS) EVBL4423A-Q-00A Evaluation Board is designed to evaluate the MP4423A and MPQ4423A switching voltage regulators. These regulators are high-frequency, synchronous, rectified, stepdown, and switch-mode converters with built-in power MOSFETs. The MP4423A/MPQ4423A regulators have synchronous mode operation for higher efficiency over the output current load range. The current-mode operation provides a fast transient response and eases loop stabilization. This EVBL4423A-Q-00A evaluation board comes with full protection features that include over-current protection and thermal shut down.

The EVBL4423A-Q-00A evaluation board is a fully assembled and tested board that operates from 4V to 36V input voltage (VIN) range. The evaluation board features a high duty cycle for automotive cold-crank, internal soft-start, and power good indicators. This EVBL4423A-Q-00A evaluation board is used in automotive, industrial control, and distributed power systems.
