Part Number: TPS54J060

Hi,

Could you please provide VIN transient (AC) spec as below DS shown SW spec?

I can only find VIN DC spec is 18V but no transient show in DS.

Hi Ide,

Customer has another request, could you please provide max and min value in below table?

Or you can provide a tolerance in percentage which can cover below all condition?

		Min.(KHz)	Typ.(KHz)	Max.(KHz)
3.3V	4.95A		1100
1.2V	2.3A		600
3.3V	4.3A		1100
1.2V	0.95A		600
1.0V	0.8A		600

Hi Jim,

TPS54J060 is D-CAP3 and not a true fixed frequency control mode, and we can only provide the switching frequency that's in the datasheet in the EC table and the Typical Characteristics data:

If you need a rough estimate, you can expect a tolerance of about +/-15%. However, please remember that this is not a guarantee from us, and it's strictly for steady-state, FCCM mode operation. Since D-CAP3 is a variable frequency control, the frequency can also increase/decrease outside that range during transient response to maintain regulation and for fast recovery.

Thank you,
Tomoya
