JAJSBY0G August 2012 – June 2018 TPS54360
The TPS54360 has an internal digital soft-start that ramps the reference voltage from zero volts to its final value in 1024 switching cycles. The internal soft-start time (10% to 90%) is calculated using Equation 6.
If the EN terminal is pulled below the stop threshold of 1.2 V, switching stops and the internal soft-start resets. The soft-start also resets in thermal shutdown.
