ELECTRICAL CHARACTERISTICS (continued)

unless otherwise noted.) (Note 1)
Note 1:
Specifications to -40
°
C are guaranteed by design, not production tested.
Note 2:
If V+ is less than 5V, V+ must be connected to VL. If VL is connected to V+, V+ must be between 4.5V and 5.5V.
Note 3:
DC output accuracy specifications refer to the trip-level error of the error amplifier. The output voltage will have a DC regula-
tion higher than the trip level by 50% of the ripple. In PFM mode, the output will rise by approximately 1.5% when transition-
ing from continuous conduction to no load.
Note 4:
One-shot times are measured at the DH pin (V+ = 15V, C
DH
= 400pF, 90% point to 90% point). Actual in-circuit times may
be different due to MOSFET switching speeds.This effect can also cause the switching frequency to vary.
