TAS5760M: Bootstrap Capacitance

Part Number: TAS5760M

Hi,

The bootstrap capacitance is 0.22uF on design sample of the datasheet.

However my customer must change this value because arranging for 0.22 uF capacitors is so difficult.

Could you show me another recommended value of boot capacitance ?

If it is difficult to source 0.22uf caps, our recommendation would be 2 0.1uF caps in parallel.

Hi Andy-san,

Thank you for your quick response.

I have an additional question.
Could you please show me the min/max recommended boot capacitance?

Best Regards,
Kuramochi

Hi Kuramochi-san,

This device has been optimized for 0.22uF caps and therefore there is no min/max.
