The TPA3221EVM HD-Audio evaluation module demonstrates the TPA3221 integrated circuit from Texas Instruments. TPA3221 is an ultra-low idle-loss Class-D amp which keeps your system cooler and your battery playing longer while supporting 100kHz high resolution audio and features single-rail power supply support, gain settings, mute, and integrated protection.View Design
The InnoSwitch3-Pro series family of ICs dramatically simplifies the development and manufacturing of fully programmable, highly efficient power supplies, particularly those in compact enclosures. The universal I2 C interface enables dynamic control of output voltage and current along with many configurable features. Telemetry provides reporting of programmed features and fault modes.View Design
The LinkSwitch-TN2 family of ICs for non-isolated off-line power supplies provide dramatically improved performance compared to traditional linear or cap-dropper solutions. Designs using the highly integrated LinkSwitch-TN2 ICs are more flexible and feature increased efficiency, comprehensive system level protection and higher reliability. The device family supports buck, buck-boost and fly back converter topologies.View Design
