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.

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.

The UCC28063 is a dual-phase, transition-mode Power Factor Correction (PFC) pre-regulator. The UCC28063EVM-723 is an evaluation module (EVM) with a 390-V, 300-W, dc output that operates from a universal input of 85 VRMS to 265 VRMS and provides power-factor correction.

The EPC9051 is a high efficiency, differential mode class-E amplifier demonstration board that can operate up to 15 MHz. This board may also be used for applications where a low side switch is utilized. Examples include, and are not limited to, push-pull converters, current-mode Class D amplifiers, common source bi-directional switch, and generic high voltage narrow pulse width applications such as LiDAR.
