TPS54202: recommendation to replace tps54202. P2P compatibility, soft time is lower than 3.5mS

Tool/software:

Hi,

Is there any p2p compatibility IC for TPS54202, which should support <3.5mS softstart time?

background:

The TPS54202 was designed originally and its soft start time is about 5mS. To provide 1.2V power rail, its slew rate is about 240v/S which can't meet  ramp up slew rate >330V/S needed by a TI's DSP's 1.2V power rail.
