Abstract
A power converting circuit and a feedback control circuit for the power converting circuit are disclosed. The feedback control circuit comprises a feedback controller and a level controlling unit. The feedback controller generates a feedback control signal according to a reference voltage signal and a feedback signal. The level controlling unit receives one of the reference voltage signal and the feedback signal and modules a level of the received signal from a first level to a second level with time according to a level adjusting signal.
Claims21
A feedback control circuit, comprising:
- a feedback controller, generating a feedback control signal according to a reference voltage signal and a feedback signal;
