SI1128 Datasheet - SANY Semiconductor

SI1128 High Precision CC/CV Primary-Side Controller

The SI1128 is an excellent primary side feedback controller, which integrates several functions of protections. It minimizes the components counts and is available in a tiny SOT-26 package. Those make it an ideal design for low cost applications. SI1128 is especially designed for below 10W applicati.
