MB39C831 | Cypress Semiconductor


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 is possible to start-up from 0.35 V and 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.

Key Features:

  • Power Converter Type: Boost
  • Temperature Range: -40˚C-+85˚C
  • Quiescent Current: 32 µA
  • Input Voltage Range: 0.3 V-4.75 V
  • Output Voltage (V): 3.0, 3.3, 3.6, 4.1, 4.5, 5.0
  • Package: 40-pin QFN
  • Status: Production
