LT LTC3225EDDB#TRMPBF

超级电容器充电器20µA2.8V ~ 5.5V

Overview

The LTC3225/LTC3225-1 are programmable supercapacitor chargers designed to charge two supercapacitors in series to a selectable fixed output voltage (4.8V/5.3V for the LTC3225EDDB and 4V/4.5V for the LTC3225-1) from input supplies as low as 2.8V to 5.5V. Automatic cell balancing prevents overvoltage damage to either supercapacitor. No balancing resistors are required.

The LTC3225/LTC3225-1 are available in a 10-lead 2mm × 3mm DFN package.
