Figure 24. Power Dissipation Profile of Application Using Charge Pump
Reference application with:
? Pump capacitor: 1.0 ? F MLC
? Pump filter capacitor: 47 ? F low ESR aluminum electrolytic
? Pump diodes: MUR120
? Output FET gate charge: 240 nC @ 10 V
? PWM Frequency: 20 kHz
? Switching Single Phase
Below approximately 17 V the charge pump is actively regulating V PWR . The increased power dissipation is due to the charge
pump losses. Above this voltage the charge pump oscillator shuts down and V SYS is passed through the pump diodes directly to
V PWR .
