LTK5302 Description:
    The LTK5302 is a built-in synchronous BOOST audio amplifier that delivers up to 11W of output power at 2Ω loads.
    The LTK5302 can adjust the boost voltage gear externally, which is suitable for various application conditions. At the same time, the EN pin line pulse control function can control a single pin to make the chip enter the Class D common mode, Class D anti-break mode, Class AB mode, and off mode, achieving the purpose of saving IO ports and further saving costs for customers.
    The LTK5302 completely eliminates EMI interference in Class AB mode. The new filterless structure can eliminate the output low-pass filter of the traditional Class D amplifier, and the LTK5302's unique DRCDynamicrange control (DRCDynamicrange Control) technology can reduce the distortion caused by waveform cutting during high-power output. Compared with similar products, The dynamic response is even better.
    The LTK5302 comes in an ESOP-10 package.
