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.

The MCP73833 Li-Ion Battery Charger Evaluation Board is an evaluation and demonstration tool for Microchip’s MCP73833/4 Stand-Alone Linear Li-Ion/Li-Polymer Charge Management Controllers. The evaluation board has two circuits provided with one circuit fully assembled and tested.

The TPS20xxCDRCEVM-016 and TPS20xxCDGNEVM-015 are evaluation modules (EVM) for the Texas Instruments family of dual-channel, current-limited, power distribution switches.

The board is a 35 W, wide-range mains input, power factor corrected SMPS (switched mode power supply) suitable for all low power applications requiring a high PF (power factor), such as lighting applications and power supplies for LEDs. The low-cost L6562A and the simple flyback topology combine to provide a very competitive PFC controller solution.

The L4981 integrated circuit is a continous mode average current controller with several specific functions for active power factor correction. It can operate in high quality, medium/high power conversion range and provides all the necessary features to achieve a very high power factor, up to 0.99. Thanks to the BCD technology used, operative switching frequency higher than 200kHz can be used.

Demonstration circuit 1621A features the LTM®8062, a 32V, 2A μModule® power tracking battery charger. The demonstration circuit is designed to operate from a 9.75V to 32V input source, and to charge a 2-cell battery pack to a float voltage of 7.2V.

Demonstration circuits 1645A-A, 1645A-B, 1645A-C and 1645A-D feature the LTM8061, a 32V, 2A μModule® Li-Ion battery charger. Operating from a 6.5V to 32V input source, the 1645A-A and 1645A-B demo circuits charge single cell Li-Ion batteries to float voltages of 4.1V or 4.2V respectively.
