MB39C831 Datasheet | Cypress

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 m A - 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 - e Book - Electronic dictionary - Wireless remote controllers - Sensor node Note: This product supports the web-based design simulation tool, Easy Design Sim. It can easily select external ponents and can display useful information.
