Super Cap Charger Features Active Balancing

Super Cap Charger Features Active Balancing
Linear Technology Corp.

The LTC3128 input-current-limited, buck-boost super capacitor charger integrates active charge balancing for 1 or 2 series supercapacitors. Active charge balancing eliminates dissipative external ballast resistors, ensuring balanced operation and charging with mismatched capacitors, and less frequent recharge cycles. The device features an average input current limit that can be programmed up to 3A with ±2% accuracy. Available in a 4 mm x 5 mm QFN and 24-lead TSSOP, pricing starts at $3.95 each/1,000.
