Pin No. Pin Name Pin Description 1 VCC This pin is connected to an external auxiliary voltage and supplies the controller. When above a certain level, the part fully latches off. 2 FB Feedback input. Hooking an optocoupler collector to this pin will allow regulation. 3 CS This pin monitors the primary peak current but also offers a means to introduce.
include: a timer to detect an overload or a short−circuit event with auto−recovery or latch protection, and a built−in VCC overvoltage protection.
The switcher also provides a jittered 65 kHz or 100 kHz switching frequency to improve the EMI.
