7.3 Recommended Operating Conditions

MIN NOM MAX UNIT
VIN Input voltage 2.4 5.5 V
tF_VIN Falling transition time at VIN(1) 10 mV/µs
IOUT Output current, TPS62864 (2) 0 4 A
Output current, TPS62866 (3) 0 6
TJ Junction temperature -40 125 °C
(1) The falling slew rate of VIN should be limited if VIN goes below VUVLO.
(2) Lifetime is reduced when operating continuously at 4-A output current and the junction temperature is higher than 105 °C.
(3) Lifetime is reduced when operating continuously at 6-A output current and the junction temperature is higher than 85 °C.
