Overview

The CS1610A/1A/12A/13A is a digital control IC engineered to

deliver a high-efficiency, cost-effective, flicker-free, phase-

dimmable, solid-state lighting (SSL) solution for the incandescent

lamp-replacement market. The CS1610A/11A is designed to

control a quasi-resonant flyback topology. The CS1612A/13A is

designed to control a buck topology. The CS1610A/12A and

CS1611A/13A are designed for 120VAC and 230VAC line

voltage applications, respectively.

The CS1610A/11A/12A/13A integrates a critical conduction

mode (CRM) boost converter that provides power factor

correction and dimmer compatibility with a constant output

current, quasi-resonant second stage. An adaptive dimmer

compatibility algorithm controls the boost stage and dimmer

compatibility operation mode to enable flicker-free operation to

<2% output current with leading-edge, trailing-edge, center-cut,

and digital dimmers (dimmers with an integrated power supply).

Applications

• Dimmable Retrofit LED Lamps

• Dimmable LED Luminaries

• Offline LED Drivers

• Commercial Lighting
