Heatsink for TPA3116D2 HTSSOP package

Other Parts Discussed in Thread: TPA3116D2

Hi,

We are using TPA3116D2 Class-D for subwoofer (50W, 6 ohms) speaker.

But our PCB size is such that it cannot fit the recommended HEATSINK (ATS-TI 10 OP-521-C1-R1) in datasheet.

Its length is 50MM. Our PCB size is 45MM.

I need to know equivalent but SMALL heatsink (MAX length = 40MM) that fits our design.

TPA3116 is used in PBTL mode, to drive 50W, 6 ohms, 6 inch subwoofer speaker. Our design is as following:

Please LMK ASAP.

Thanks,

Karthik
