Note:
1
Minimum and maximum limits are guaranteed by test, design, or statistical correlation.Typical values
represent the most likely parametric norm at TA = 25 °C, and are provided for reference only.
2
Device thermal limitations could limit useful operating range.
3
The VC regulator is intended for internal use only as the startup supply of the PM8803; any additional
external VC current, including the VB regulator current and external MOSFET driving current, has to
be limited within the specified max current limit.
