TPS53219A: Ref design dc 20V input

Hi,

I have new request as follows:

• 20V nominal input, max acceptable up to 24V
• Max output current= 15.5A
• Output voltage= 0.9V
• Transient 0.8A =>7.3A in 2us (6.5A inrush in 2us) with less than 20mV drop

I identified tps53219a + csd87330q3d as good fit.

Customer would TI to confirm feasibility. One major concern is about voltage drop of 20mV for load transient 6.5A in 2us.

=> can we provide schematic to meet customer spec above ?

=> do we have simulation results or measurements to prove we can achieve customer spec for transient load ?

regards,

Paul
