NCP1249D Product details

Description

When the voltage on this pin disappears, the controller ensures the X2 capacitors discharge. coupler can pull the feedback pin down and brings the controller in a deep sleep mode.This pin monitors the primary peak current but also offers a means to introduce slope compensation.A resistive divider from the auxiliary winding to this pin sets the OPP compensation level.When brought above 3 V, the part is fully lat
