Hi Sir,

Is TPS53355ADQPR the same as TPS53355DQPR except of the operating temperature?

The operating temperature of TPS53355ADQPR is -40~+85C while the operating temperature of TPS53355DQPR is -40~+125C.

Thanks,

Hi

    芯片的操作温度都是-40℃~125℃。

    一般后缀带A是噪声改善版本。

    另外你可以看一下datasheet 第三页改到A版本的说明, 主要是输入电压从3V下降到1.5V,  但实际上现在都是1.5V最小输入。
