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
