TIDA-00223 Automotive Audio I2S over Coax Class D Amplifier Reference Design | TI.com
TIDA-00223: This reference design is an I²S/TDM-based, low-cost, easy-to-use alternative to fiber optics/analog copper wire for connecting an automotive (sound) control panel to an output stage/power amplifier. Supporting I²S as well as TDM, it is capable of transmitting digital audio signal to 16 independent channels of speakers with each channel output of 80W at 4Ω. It also supports bidirectional communication with the control unit or processor via I²C, over a single shielded twisted pair (STP) or coaxial. Furthermore, the TIDA-00223 reference design enables fast implementation with power supply included, and it has all the protection and diagnostics requirements needed in modern cars.
PMP7967 Power Solution for an Engineering Equipment Fuel Injector | TI.com
PMP7967: The PMP7967 converts a DC input of 6V-42V to an output of 90V at 1.5A. The design uses four interleaved LM5122 boost controllers with each controller switching at 100kHz. The resulting 4-phase boost converter has a ripple frequency of 400kHz. Freqeucny can also be synchronized to an external signal. Four 330μF aluminum electrolytic capacitors are used at the output to support sudden load current demands in the fuel injector solenoids.
