7.3 Recommended Operating Conditions

Over operating junction temperature range (unless otherwise noted)
MIN NOM MAX UNIT
VIN Input voltage range 2.4 5.5 V
VOUT Output voltage range 0.6 4.0 V
IOUT Output current range, TPS62089A 0 2 A
IOUT Output current range, TPS62088, TPS62088A (1) 0 3 A
ISINK_PG Sink current at the PG pin 1 mA
VPG Pullup resistor voltage 5.5 V
TJ Operating junction temperature -40 125 °C
(1) For YFP package versions, lifetime is reduced when operating continuously at 3-A output current with the junction temperature higher than 85°C.
