The following document contains information on Cypress products. FUJITSU SEMICONDUCTOR DATA SHEET DS405-00014-0v01-E Ultra Low Voltage Boost Power management IC for Solar/Thermal Energy Harvesting MB39C831 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 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) 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 : 0.3 V to 4.75 V Output voltage adjustment range : 3.0 V to 5.0 V Minimum input voltage at start-up : 0.35 V Quiescent Current (No load) : 41 A 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 mult iple cells solar cell/Super Capacitor Charger Portable audio players Cellular phone eBook Electronic dictionary Wireless remote controllers Sensor node Copyright2013 FUJITSU SEMICONDUCTOR LIMITED All rights reserved 2013.6
