BU1840AMUV Overview
The BU1840AMUV device provides the best system to the product charged with 1cell Li-ion battery and 3cell Nickel-metal-hydride batteries using the 2cell, 3cell, and 4cell solar panel. It is possible to boost it according to the voltage of 2 cell solar panel with built-in the function to boost the low voltage input. Moreover, the solar battery maximum dissipation can be drawn out with built-in the peak power track...
