Note:
1 Minimum and maximum limits are guaranteed by test, design, or statistical correlation.Typical values
represent the most likely parametric norm at T_A = 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.
