MERUS™ D 类音频放大器 IC、多芯片模块和分立的 MOSFET/HEMT 驱动器 IC

传统的 D 类放大器是一种开关放大器，通常由两个带脉宽调制（PWM）信号的功率 MOSFET 组成。对于输出水平超过 20 瓦的情况，需要一个 LC 滤波器，这会增加尺寸和成本。

 

随着每个产品中的音频通道数量不断增加，传统的 D 类功率放大器在紧凑型应用中面临设计挑战：低功率效率、过多的热量生成（即使在中等听音水平下），以及需要笨重且昂贵的滤波器。英飞凌的多级 D 类音频放大器电路技术——全球首创——使其能够在减少电磁干扰和带外噪声的同时，改善功耗。通过消除或最小化滤波器的使用，可以降低制造成本，从而节省设计空间。

 

凭借革命性的多级 D 类放大器 IC，英飞凌在功率效率和功率密度方面处于领先地位。更酷、更小、更轻的 D 类音频放大器，打造出色的音频产品。
