DC1583A-B is a 1A high efficiency 2-Cell supercapacitor charger with automatic cell balancing featuring the LTC3625-1. The LTC3625-1 are programmable supercapacitor chargers designed to charge two supercapacitors in series to a fixed voltage of 4.5V/4.0V from a 2.7V to 5.5V input supply. Automatic cell balancing is achieved during the charging phase, preventing overvoltage damage to either supercapacitor while maximizing charge rate.

DC1887 is a DC/DC supercapacitor buck-boost charger and balancer converter featuring the LTC3128. The DC1887A operates over 1.72V to 5.5V input and charges the output up to 5.5V. Also, the LTC3128 has 2% precision input current limit, which allows the circuit to operate effectively with current limited input power sources like the USB.

DC1735A is a 2-cell supercap charger with a backup PowerPath controller, featuring the LTC3226. It includes a charge-pump supercapacitor charger with programmable output voltage, a low dropout regulator and a power-fail comparator for switching between normal and backup modes.

DC1220B is a Low Profile Regulated Dual Cell SuperCAP Charger featuring the LTC3225. The LTC3225 is a constant-current SuperCAP charger designed to charge two SuperCAPs in series to a fixed output voltage of 4.8V or 5.3V from a 2.9V to 5.5V input supply.

Demonstration circuit 2464A-A is a supercapacitor charger and backup controller with a hot swappable front end plus supercapacitor health and system monitoring; featuring the LTC3351.

The MAL219699003E3 mini charger and backup demonstration circuit is a fully transparent charger unit that uses a BQ24095 charging IC and TPS610997 boost converter IC from Texas Instruments to boost the capacitor voltage up to a 5 V constant output voltage.

Demonstration circuit 2464A-B is a supercapacitor charger and backup controller with a hot swappable front end plus supercapacitor health and system monitoring; featuring the LTC3351.

The DC1589A is a constant-current/constant-voltage linear charger circuit designed to charge a 2-cell supercap stack from either a Li-Ion/Polymer battery, a USB port, or a 2.7V to 5.5V current-limited supply. The part operates as an ideal diode with an extremely low 50mΩ on-resistance making it suitable for high peak-power/low average power applications.

DC1964A is a 2A, bidirectional buckboost DC/DC regulator and charger/balancer, featuring the LTC®3110 boost controller. Its wide voltage range both in capacitor/battery charger mode and in system backup mode makes it well suited to a wide variety of applications using supercapacitors and batteries.

The circuit implemented on the board is a simple example of how to charge a 400uF capacitor to 300V in approximately one second at 8Vin and 400ms at 40Vin. An output capacitor discharge circuit is included on the board for the convenience of the user.
