Description The SPV1050 is an ultra-low power and high-efficiency power manager embedding four MOSFETs for boost or buck-boost DC-DC converter and an additional transistor for the load connection/disconnection. An internal high accuracy MPPT algorithm can be used to maximize the power extracted from PV panel or TEG. The internal logic works to guarantee tight monitoring of both the end-of-charge voltage (VEOC) and the minimum battery voltage (VUVP) by opening the passtransistor at triggering of...
