Overview

The CS1610/11/12/13 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 CS1610/11 is designed to control a

quasi-resonant flyback topology. The CS1612/13 is designed to

control a buck topology. The CS1610/12 and CS1611/13 are

designed for 120VAC and 230VAC line voltage applications,

respectively.

The CS1610/11/12/13 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, and digital dimmers

(dimmers with an integrated power supply).

Applications & Description

• Dimmable Retrofit LED Lamps

• Dimmable LED Luminaries

• Offline LED Drivers

• Commercial Lighting
