STMicroelectronics STBLW35
The STBLW35 is an ultra-low power and high-efficiency buck-boost DC-DC converter which can work as boost or buck-boost according to the selected hardware configuration. When in buck-boost the DC-DC can seamlessly switch between the two working modes depending on operating conditions. The IC shows very low power losses either in active or disable mode and provides an average output current between 33 mA to 70 mA, suitable to guarantee load minimum current constraints or to faster charge a battery.| Part No. | STBLW35 |

DESCRIPTION
The device also allows the charge of any battery by tightly monitoring the end-of-charge and the minimum battery voltage in order to avoid overdischarge and to preserve battery life. The power manager covers the input voltage range from 150 mV up to 18 V and guarantees high efficiency in both buck-boost and boost configuration. Furthermore, the STBLW35 device shows very high flexibility thanks also to the trimming capability of the overvoltage and the undervoltage protection voltages.
