9.3.1.2.3 Charge Pump VCAP, Input and Output Capacitance

Minimum required capacitance for charge pump VCAP and input/output capacitance are:

  • VCAP: Minimum 0.1 µF is required; recommended value of VCAP (µF) ≥ 10 x CISS(MOSFET) (µF)
  • CIN: Typical input capacitor of 0.1 µF
  • COUT: Typical output capacitor 220 µF
