PRODUCTION DATA
TON_RISE is a paged register. The TON_RISE command sets the time in milliseconds, from when the output starts to rise until the voltage has entered the regulation band. It also determines the rate of the transition of the reference voltage (either due to VREF_TRIM or STEP_VREF_MARGIN_x commands) when this transition is executed during the soft-start period. There are several discrete settings that this command supports. Commanding a value other than one of these values results in the nearest supported value being selected.
The supported TON_RISE times via the PMBus interface are:
A value of 0 ms instructs the unit to bring its output voltage to the programmed regulation value as quickly as possible. The contents of this register can be stored to non-volatile memory using the STORE_USER_ALL command.
The TON_RISE command is formatted as a linear mode two’s complement binary integer.
