ELECTRICAL CHARACTERISTICS (continued)
(V OUTS = V POUT = 5V, V ON = V BATT = 3.6V, V SKIPB = GND, T A = -40°C to +85°C, typical values are at T A = +25°C, unless otherwise
noted. Limits are 100% production tested at T A = +25°C. Limits over the operating temperature range are guaranteed by design and
characterization.)

Note 3: Guaranteed by design. Not production tested.
Note 4: The idle-mode current threshold is the transition point between fixed-frequency PWM operation and idle-mode operation. The
specification is given in terms of output load current for inductor values shown in the typical application circuits (Figure 1). The
idle-mode transition varies with input-to-output voltage ratio.
