Abstract
Official abstract text for this publication.
An isolated switching mode power supply, having: a transformer having a primary winding, a secondary winding and a third winding; a current limit comparator configured to provide a current limit signal based on the current sense signal and the peak current signal; a logic circuit configured to provide a logic control signal based on the frequency control signal and the current limit signal; a startup control circuit configured to generate a startup control signal based on the current sense signal; a load detecting circuit configured to provide a load detecting signal based on the second feedback signal and the switching signal; and a selector configured to provide the logic control signal or the startup control signal based on the load detecting signal.
First claim
Opening claim text (preview).
We claim: 1. An isolated switching mode power supply, comprising: a transformer having a primary winding, a secondary winding and a third winding, the primary winding being configured to receive an input signal, the secondary winding being configured to provide an output voltage, the third winding being configured to generate a second feedback signal indicative of the output voltage; a primary power switch coupled between the primary winding and a primary ground node, the primar…
