Note:

1. In Single-Cell Boost and Boost Bootstrap configurations (e.g., EFP0108 and EFP0111), the LDO C input (VDDB) is powered by

the DCDC A output (VOA). Therefore, the maximum output current of LDO C will also be limited by the maximum output current

of the DCDC A converter.

2. In Single-Cell Boost (EFP0108) and Boost Bootstrap (EFP0111) configurations, the LDO C input (VDDB) is powered by the

DCDC A output (VOA). Therefore, the maximum output voltage at VOC will be limited by the VOA output voltage.

3. Maximum output load current is determined by first measuring the output voltage with a 5mA load. Maximum output load is the

the maximum load at which measured output voltage is no lower than 50mV from the original 5mA load measured voltage.

4. Specifications assume minimum LDO dropout requirement has been met (i.e., VDDB - VOC > 365mV)

5. For converters enabled by default, total startup time will be TSTART + TBOOT (found in the General Operating Conditions table)
