relation using statistical quality control (SQC) methods.

Note 3: The USB/DC current limit does not include the VL output current. See the

VL Linear Regulator section for more information.

Note 4: Quiescent current excludes the energy needed for the REG1–REG5 external resistor-dividers. All typical operating charac-

teristics include the energy for the REG1–REG5 external resistor-dividers. For the circuit of Figure 1, the typical quiescent

Note 5: The charger transitions from done to fast-charge mode at this BAT recharge threshold (Figure 7).

Note 6: The charger transitions from fast-charge to top-off mode at this top-off threshold (Figure 7).

Note 7: The maximum output current is guaranteed by correlation to the p-channel current-limit threshold, p-channel on-resistance,

n-channel on-resistance, oscillator frequency, input voltage range, and output voltage range. The parameter is stated for a

4.7µH inductor with 0.13

Ω series resistance. See the Step-Down Converter Output Current section for more information.

Note 8: The step-down output voltages are 1% high with no load due to the load-line architecture. When calculating the external

resistor-dividers, use an FB_ voltage of 1.000V.

Note 9: Line regulation for the step-down converters is measured as

Note 10: The skip mode current threshold is the transition point between fixed-frequency PWM operation and skip mode operation.

The specification is given in terms of output load current for inductor values shown in the typical application circuits.
