  RE: TPS5420: Inrush start-up current limit.

  Eduardo, The slow-start (aka soft-start) time is 6.6ms min, 8ms typ, 10ms max. You can use your output capacitance, output voltage, and this timing to calculate your worst case startup current. -Sam

  TPS5420: Random start-up problems

  TI Thinks Resolved

  Part Number: TPS5420 I am using an open drain mosfet to control en (pin 5) on controller. Sometimes the chip doesn't start - no output. The mosfet I am using is a ROHM SM6K2. It is maximum leakage of 1uA at 60v. I am turning him off with another SM6K2...
