MB39C811
Ultra Low Power Buck PMIC
Solar/Vibrations Energy Harvesting
The MB39C811 is the high efficient buck (Power Management) DC/DC converter IC which adopts the all-wave bridge
rectifier using the low-dissipation and the comparator system. It achieves the energy harvest solution for the energy
source of the high output impedance such as the piezoelectric transducer.
It is possible to select from eight preset output voltages and supply up to 100 mA of the output current.
Features
Quiescent current (No load, Output in regulation):
1.5µA
Quiescent current (VIN = 2.5V UVLO): 550nA
Integrated Low Loss Full-Wave Bridge Rectifier
VIN input voltage range: 2.6V to 23V
Preset output voltage: 1.5V, 1.8V, 2.5V, 3.3V, 3.6V,
4.1V, 4.5V, 5.0V
Applications
Output current: Up to 100mA
Protection functions
