Overview
MB39C831 Ultra Low Voltage Boost Power Management IC for Solar/Thermal Energy Harvesting Datasheet Description 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 solar cell (MPPT: Maximum Power Point Tracking) and the protection function to charge the Li-ion battery safely.
It is possible to start-up from 0.
35 V using the low-voltage process and adapts the applications which the single cell solar cell is treated as the input.
Features  Operation input voltage range : 0.
3V to 4.
75V  Output voltage adjustment range : 3.
0V to 5.
0V  Minimum input voltage at start-up : 0.
35V  Quiescent Current (No load) : 41 μA  Input peak current limit : 200 mA  Built-in MPPT  Charge voltage to the Li-ion battery/current protection function built in  Improvement of the efficiency during the low-output power according to the auto PFM/PWM switching mode Applications  Solar energy harvesting  Thermal energy harvesting  Li-ion battery using the single cell or multiple cells' solar cell/Super Capacitor Charger  Portable audio players  Cellular phone  eBook  Electronic dictionary  Wireless remote controllers  Sensor node Note: This product supports the web-based design simulation tool, Easy DesignSim.
It can easily select external components and can display useful information.
