Start-up time is defined as the time from the moment EN1 = EN2 = EN3 transfers from 0 V to VAVIN to the moment VOUT1, VOUT2, and VOUT3 reache 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.

BUCK SPECIFICATIONS

AVIN, VIN1 = 2.3 V to 5.5 V; VOUT1 = 1.8 V; L = 1 µH; CIN = 10 µF; COUT = 10 µF; TJ= −40°C to +125°C for minimum/maximum

specifications, and TA = 25°C for typical specifications, unless otherwise noted.1
