The MR163 built-in power-on soft-start function, the time of soft-start is adjusted by C2 capacitor, R1 is current senese for LED, when the sense current time the R1 would generate a sense feedback voltage to IC IN- terminal, IC should turn off LX1 and LX2 and keep L1 energy transfer to Vout and hold the LED lighting until and sense current isn’t enough. C3 and C4 are the capacitors and they keep the supply and Vout voltage smoothly. It is a few external parts using and reduced PCB space very suitable for a tiny LED light system environment.
