MIN MAX UNIT
VIN Input voltage 3 17 V
VPG Power good pull-up resistor voltage 6 V
VOUT Output voltage 0.9 6 V
IOUT Output current 0 2 A
TJ Module operating temperature range for 100,000 hours lifetime(1) -40 110 °C
(1) The module operating temperature range includes module self temperature rise and IC junction temperature rise. In applications where high power dissipation is present, the maximum operating temperature or maximum output current must be derated. For applications where the module operates continuously at 125 °C temperature, the maximum lifetime is reduced to 50,000 hours.
