Isolated/non-isolated offline 120vac/230vac

SOP Package

5 Application Range: Candle lamp, GU10, par lamp, BR lamp, R lamp, bulb lamp, etc.

Scheme name: Iwatt (Ayvat) 20W within the SCR dimming scheme

Programme characteristics;

The simple advantages of the overall cost, high and low pressure to adjust the light can achieve the perfect dimming effect. Non-isolated applications require simple, low-cost inductors for single windings.

Basic compatibility with more than 90 of the market, dimming depth for most dimmer can be as low as 1%

Compared to other brand schemes (e.g. Nxp/mps/ti, etc.) the Bleeder circuit is saved, the VCC supply voltage can be started at 5V and the output voltage range is wide.
