FUJITSU SEMICONDUCTOR DATA SHEET DS405-00013-0v01-E Ultra Low Power Buck Power Management IC for Solar and Vibrations Energy Harvesting MB39C811 DESCRIPTION The MB39C811 is the high efficient buck 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) : 1.5 A Quiescent current (VIN = 2.5 V UVLO) : 550 nA Integrated Low Loss Full-Wave Bridge Rectifier VIN input voltage range : 2.6 V to 23 V Preset output voltage : 1.5 V, 1.8 V, 2.5 V, 3.3 V, 3.6 V, 4.1 V, 4.5 V, 5.0 V Output current : Up to 100 mA Protection functions - Shunt for input protection : VIN 21 V, Up to 100 mA Pull-down - Over current limit I/O Power-Good detection signal output APPLICATIONS Light energy harvesting Piezoelectric energy harvesting Electro-Mechanical energy harvesting Wireless HVAC sensor Stand-alone nano-power buck regulator Copyright2013 FUJITSU SEMICONDUCTOR LIMITED All rights reserved 2013.6
