Product Overview

The LTC3625EDE#PBF is a Programmable Supercapacitor Charger designed to charge two supercapacitors in series. No balancing resistors are required. High efficiency, high charging current, low quiescent current and low minimum external parts count (one inductor, one bypass capacitor at VIN and one programming resistor) make the device ideally suited for small form factor backup or high peak power systems. Charging current/maximum input current level is programmed with an external resistor. When the input supply is removed and/or the EN pin is low, the device automatically enters a low current state, drawing less than 1µA from the supercapacitors.
  • High efficiency step-up/step-down charging of two series supercapacitors
  • Automatic cell balancing prevents capacitor overvoltage during charging
  • Programmable charging current up to 500mA (Single inductor), 1A (Dual inductor)
  • Selectable 2.4V/2.65V Regulation per cell
  • 23µA Low no-load quiescent current
  • Green product and no Sb/Br
