EVQ2178A-LE-00A

EVQ2178A-LE-00A is an evaluation board designed to demonstrate the capabilities of the MPQ2178A, a monolithic, step-down switch-mode converter with built-in internal power MOSFETs. The EVQ2178A-LE-00A can achieve up to 2A of output current (IOUT) across a 2.5V to 5.5V input voltage (VIN) range, with excellent load and line regulation. The output voltage (VOUT) can be regulated to as low as 0.6V. Fault protections include cycle-by-cycle current limiting and thermal shutdown. The EVQ2178A-LE-00A is a fully assembled and tested evaluation board. It generates a 1.2V VOUT at load currents up to 2A across a 2.5V to 5.5V VIN range. The MPQ2178A is available in a compact QFN-8 (1.5mmx2mm) package, and it is AEC-Q100 qualified.
