(1)

VIN is defined as the highest voltage present on the BAT, USB and DC_IN pins.

(2)

One of the voltages on BAT, USB and DC_IN must be > VIN (Min), others can be 0 V.

(3)

VBAT, VUSB and VDC_IN refer to the voltages on BAT, USB and DC_IN respectively. OUT, IOUT-VOUT and IOUT-LOUT refer to the

currents for the combined output current for VOUT and LOUT, the current on VOUT and the current on LOUT respectively.

(4)

TYP is 25ºC, BAT = 4.2-V, USB = 0-V, DC_IN = 0-V.

(5)

Dropout voltage is the minimum input to output voltage differential needed to maintain regulation at a specified output current. In

dropout, the output voltage is equal to: VIN – VDROPOUT.

(6)

Dropout voltage is measured at the VIN that causes the output to drop to 100mV below its nominal voltage. For VOUT, the voltage drop

across the output switch is included (10mA × RONVOUT).
