MB39C831 - Cypress Semiconductor

MB39C831 Ultra Low Voltage Boost Power Management IC

The MB39C831 is the high-efficiency synchronous rectification boost DC/DC converter IC which efficiently supplies energy getting from the solar cell with the single cell or multiple cells, or from the thermoelectric generator (TEG) to the Li-ion battery. It contains the function to control the DC/DC converter output following the maximum power point of the s.
