Info & Free Samples
The LTC®3128 brings a new level of performance to supercap charging with its high level of integration and unique buck-boost
topology. It charges capacitors at up to 3A, from ground to voltages above VIN – up to 5.5V. Accurate programmable average input current limit, active charge balancing and programmable maximum capacitor voltage ensure the life and health of the supercaps. Other features include low quiescent current, accurate power good, power failure indicators and thermal overload protection.
