NOTE: 1. Output current capability is reduced with supply voltage due to decreased energy transfer. The supply voltage must not be higher than
VMAIN+0.6V to ensure boost operation. Max Start−up loading is typically 1V at 400 μA, 1.8V at 4.4 mA, and 2.2V at 88 mA.
NOTE: 2. Output voltage can be adjusted by external resistor to the VMAINFB pin.
NOTE: 3. At VBAT = 1.8V, output current capability increases with VBAT.
NOTE: 4. Only when current limit is not reached.
NOTE: 5. This is average current consumed by the IC from VDD, which is low−pass filtered from VMAIN, when only VMAIN is enabled and at no loading.
NOTE: 6. This is the minimum of ”LOWBATB” threshold for battery voltage, the threshold can be increased by external resistor divider from ”VBAT” to
”LOWBATSEN”.
