Upgraded TPA3255 2.0 DC1940V PBTL 600W 315W 3

Now It's the latest version , it is the product after the change, which has completely improved the common problem of high voltage protection.
The use of 50V is also completely normal, and the use of materials is also more feverish. The auxiliary power supply uses Class A linear power supply, which is more dynamic, and the sound quality is significantly improved! It can perfectly drive 2-16 Euro speakers!
TPA3255 is a high-performance class D power amplifier chip, which has class D efficiency and can bring true high-end audio quality circuit. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath ™ UHD).
This technology can enable the device to maintain ultra-low distortion in the entire audio frequency band, while displaying sound quality. The device works in AD mode. When the is 1.5%, it can drive up to two 315W/4R loads and two 150W (unshipped power)/8R loads, and has a unique 2 VRMS analog input interface, which supports seamless connection with high-performance DAC (such as TI's PCM5242).
In addition to audio performance, TPA3255 also has two advantages: efficiency and ultra-low power level idle loss (less than 2.5W). This can be achieved through 85mR MOSFET and optimized gate driver scheme. Compared with the discrete implementation scheme, this scheme can significantly reduce idle loss.
