Product Overview

The LTC3128IUFD#PBF is a highly efficient Buck-Boost DC/DC Supercapacitor Charger with balancer. It operates efficiently from input voltages above, below or equal to the output voltage. The LTC3128 incorporates accurate programmable average input current limit, active charge balancing and programmable maximum capacitor voltage. This combination of features makes the LTC3128 ideal for safely charging and protecting large capacitors in backup power systems. The input current limit and maximum capacitor voltage are each programmed using a single resistor. Average input current is accurately controlled over a 0.5A to 3A programmable range while the individual maximum capacitor voltage can be set from 1.8V to 3.V.
  • ±2% Accurate average input current limit programmable up to 3A
  • Programmable maximum capacitor voltage limit
  • Active charge balancing for fast charging of unmatched capacitors
  • Charges single or stacked capacitors
  • 1.8 to 5.5V Output voltage range
  • <2µA Quiescent current from VOUT when charged
  • <1µA IQ Output disconnect in shutdown
  • Power-good comparator
  • Power failure indicator
  • Thermal overload protection
  • Green product and no Sb/Br
