Product details

Description

Pin Symbol Name Function 1 FB / SD Feedback / This pin receives a feedback current IFB which is proportional to the PFC circuit output voltage.Shutdown The current is for output regulation, output overvoltage protection (OVP), and output undervoltage protection (UVP).When IFB goes above 107% Iref, OVP is activated and the Drive Output is disabled.When IFB goes below 8% Iref, the device enters a low consumption shutdown mode.
