Monolithic Power Systems (MPS) EVQ2178A Evaluation Board

Monolithic Power Systems (MPS) EVQ2178A Evaluation Board is designed to demonstrate the capabilities of the MPQ2178A, a monolithic, step-down switch-mode converter with built-in internal power MOSFETs. This evaluation board features up to 2A output current, 0.6V output voltage, and 2.5V to 5.5V input voltage range, with load and line regulation. The EVQ2178A board features fault protections that include cycle-by-cycle current limiting and thermal shutdown. Typical applications include automotive clusters, telematics, infotainment systems, camera modules, key fobs, industrial supplies, and battery-powered devices.
