Part Number: TPS563210A

Hi support team.

I received an inquiry about a value of discharge resistance and detail of discharge circuit from my customer.

Please tell me about a value of discharge resistance?

TPS56x210A have a output discharge circuit is correct?

Best regards.

Hi Higa,

There is no data for this resistor on easy table, but we found this discharge circuit in the IC schematics. I will double check on our EVM and will get back to you later.

Best,

Anthony

Hi Anthony

Thank you for your quickly reply.
My customer requests quickly discharge(less than 100ms under connected 100uF capacitor).

Do TPS56x210A have a self-discharge mode?

Best regards.

Hi Higa,

I did some test in the lab. A voltage is applied on SW when EN =0. The current is measured to calculate this discharge resistor. Here is the data I got:
