TPS65185: DC-DC2 Opetation Mode

user5020444

Part Number: TPS65185

To whom it may concern:

I am writing to inquire about the modulation technology of the IC TPS65185, due to the datasheet has not annotated. Could you tell us the modulation technology of TPS65185 DC-DC2 is pulse width modulation(PWM) or pulse frequency modulation(PFM)?

Hi Min,

Referencing Figure 7 in the datasheet, it appears VN operates in PFM mode.
