EVBL2171-J-00A

EVBL2171-J-00A is an evaluation board designed to demonstrate MP2171 and MPQ2171. The board features an integrated MPS power inductor. The MP2171 is a low voltage, high frequency, step-down switch mode converter with integrated, internal power MOSFETs. It can achieve up to 1A of highly efficient output current (IOUT) across a wide 2.5V to 5.5V input voltage (VIN) range with constant-on-time (COT) control for fast loop response. The device is ideal for powering portable equipment that runs on a single-cell Lithium-ion (Li-ion) battery. Its output voltage (VOUT) can be regulated to as low as 0.6V. High power efficiency across the entire load range is achieved by scaling down the switching frequency (fSW) at light loads. This reduces the switching loss during COT control. The MP2171 is available in a TSOT23-8 package. Applications includes automotive infotainment systems, automotive clusters, automotive telematics, low-voltage I/O power systems, handheld and battery-powered systems.
