Description	High Precision CC/CV Primary-Side Controller
Datasheet	SI1128-SANYSemiconductor.pdf

The SI1128 is an excellent primary side feedback controller, which integrates several functions of protections.

It minimizes the ponents counts and is available in a tiny SOT-26 package.

Those make it an ideal design for low cost applications.

5% Constant Voltage Regulation, 5%Constant Current Regulation at Universal AC input.
Primary-side Sensing and Regulation Without TL431 and Opto-coupler.
Low Start-up Current: 1μA (Typical).
Low Static Current: 300μA (Typical).
Programmable CV and CC Regulation.
Adjustable Constant Current and Output Power Setting.
Built-in Secondary Constant Current Control with Primary Side Feedback.
Peak-Current-Mode Control.
Compensates for transformer inductance.
