LM5045: Full Bridge Controller

Kuan Wei Chen (Kevin Chen)

Part Number: LM5045
Other Parts Discussed in Thread: UCD8220

Dear Team,

I am looking for a suitable controller for full-bridge topology.

The LM5045's gate driving only 2 A, which customer will need an external driver.

The customer will expect with 4A driving capability or without driving capability which they can use the external driver.

Hi Kevin,

I didn't found a full-bridge part with the driver capability larger than 4A except for UCD8220, which is a digitally assisted pwm controller, I don't think customer will accept it since it needs to co-work with the digital controller.

But there are many choice for the full-bridge without driver capability, you also can find them in this page.

If you can provide the spec of full-bridge, then I can recommend a suitable part for you.

Regards,

Teng
