We are searching the audio amplifier & buck DC/DC for car 48V light hybrid system that can burden the voltage 60V,Is there some part can match the require

(1) BUCK DC/DC :60V change to 3.3V /3A,switching frequency.about2100kHz(Output voltage can regulated by resister)

(2) AUDIO AMPLIFIER: 150W*4CH@48V,can burden 60V

(3) If there is no audio amplifier can match the require ,please recommended the DC/DC controller that can buck the voltage from 60V to 45V for TAS6584 or 24V for TAS6424

LM5149 LM5148 may meet your requirements.

Thank u for replying,

(1) BUCK DC/DC :60V change to 3.3V /3A,switching frequency.about2100kHz(Output voltage can regulated by resister),FET integrate，which part can match it?

Hello,

Please take a look at the LM708x0-Q1 80V 4A/6A/8A converter family for the 3A application https://www.ti.com/product/LM70880-Q1. However, 2.1MHz seems very high given the 60V input requirement - is lower Fsw acceptable, e.g. 400kHz?

And for the other application, please review the LM5148-Q1 80V controller.

Regards,

Tim
