Figure 19. Power Dissipation Profile of Application Using Charge Pump
Reference application with:
Pump capacitor: 1
μ
F MLC
Pump filter capacitor: 47
μ
F low ESR aluminum electrolytic
Pump diodes: MUR120
Output FET gate charge: 240 nC @ 10V
PWM Frequency: 20kHz
Switching Single Phase
Below approximately 17V the charge pump is actively regulating Vpwr. The increased power dissipation is due to the charge
pump losses. Above this voltage the charge pump oscillator shuts down and Vbat is passed through the pump diodes directly to
Vpwr.
