MB39C831 Overview
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.
Key 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
