ADP3208C
ELECTRICAL CHARACTERISTICS VCC = PVCC1 = PVCC2 = BST1 = BST2 = High = 5.0V, FBRTN = GND = SW1 = SW2 = PGND1
= PGND2 = Low = 0 V, EN = VATFREQ = High, DPRSLP = 0 V, PSI = 1.05 V, VVID = 1.2000 V, TA = −40°C to 100°C, unless otherwise
noted (Note 1). Current entering a pin (sunk by the device) has a positive sign. RREF = 80 kW.

1. All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC).
2. Guaranteed by design or bench characterization, not production tested.
3. Timing is referenced to the 90% and 10% points, unless otherwise noted.
