Digital Controller IC for Dimmable LED Lighting

The IKS2053 is a high performance AC-DC SMPS controller IC for LED drivers which uses proprietary digital control techniques to achieve high PFC, high efficiency and dimmer compatibility, all in a small form factor and at low cost. The digital controller simplifies the design process, enables the elimination of external components and operates in quasi-resonant mode to maximize efficiency and simplify EMI design.

This results in a more compact design, better reliability and a reduced bill of materials cost.

A wide and linear dimming profile is enabled by the advanced dimming engine which supports both leading and trailing edge dimmers.
