Abstract:
A secondary controller drives a light emitting element of a photocoupler such that a detection voltage V OUTS  corresponding to an output voltage V OUT  generated in an output capacitor C approximates to a reference voltage V REF . A primary controller controls a switching transistor M according to a feedback signal V FB . A protection circuit is activated and drives the light emitting element of the photocoupler when detecting an abnormal state. An auxiliary power supply circuit includes a power supply capacitor C provided separately from the output capacitor C and supplies a power supply voltage V CC  to the protection circuit and an anode of the light emitting element of the photocoupler.

Claim (Index 9):
The DC/DC converter according to  claim 1 , wherein\n the feedback circuit is built in the secondary controller, the secondary controller, in addition to the feedback circuit, includes: a control output pin to be connected to the light emitting element of the photocoupler; a power supply pin to be coupled to receive the power supply voltage; a control input pin to be coupled to receive a detection voltage corresponding to the output voltage of the output capacitor; and a power supply path coupled to supply power from the control output pin to the power supply pin, and the feedback circuit is structured to amplify an error between the detection voltage and a reference voltage and supplies a current corresponding to the error to the light emitting element of the photocoupler.
