Figure 25. Power Dissipation Profile of Application Not Using Charge Pump

Reference application with:

• Output FET gate charge: 240 nC @ 10 V

• PWM Frequency: 20 kHz

• Switching Single Phase

• No connections to PUMP or VPUMP

If VPWR is supplied by a separate pre-regulator, the power dissipation profile will be nearly flat at the value of the pre-regulator
