ELECTRICAL CHARACTERISTICS
VCC = PVCC = 5.0 V, FBRTN = PGND = GND = 0 V, H = 5.0 V, L = 0 V, EN = VARFREQ = H, DPRSLP = L, PSI = 1.05 V,
VVID = VDAC = 1.2000 V, TA = −40°C to 100°C, unless otherwise noted. (Note 1) Current entering a pin (sink current) has a positive sign.

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. Based on bench characterization data.
4. Timing is referenced to the 90% and 10% points, unless otherwise noted.
