1 Start-up time is defined as the time from EN1 = EN2 = EN3 = EN4 from 0 V to VAVIN to VOUT1, VOUT2, VOUT3, and VOUT4 reaching 90% of their nominal level. Start-up

times are shorter for individual channels if another channel is already enabled. See the Typical Performance Characteristics section for more information.
