LM51772-Q1: Would like to remove Q3 and Q4 of MOSFET

Part Number: LM51772-Q1
Other Parts Discussed in Thread: TIDA-020033, , LMR43620

Tool/software:

Hi team,

My customer has been considering LM51772-Q1 to achieve the class-H solution for class D amp based on the TIDA-020033 and has a question. Could you please kindly answer it?

My customer plans to use LM51772-Q1 as buck converter only, so I think it is possible to remove Q3 and Q4 of MOSFET. The reason why my customer plans to remove Q3 and Q4 is to reduce the PCB size. May I know if it is possible to remove Q3 and Q4 of MOSFET? The requirement of power rail is below.

Input voltage: 24V battery

Output voltage: Maximum 14V

Output current: Maximum 1.5A

Best regards,

Shunsuke Yamamoto
