TRIAC Dimmable LED Driver IC

Features & Description

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.

• Best-in-class Dimmer Compatibility

- Leading-edge (TRIAC) Dimmers

- Trailing-edge Dimmers

- Center-cut Dimmers

- Digital Dimmers (with Integrated Power Supply)

• Up to 90% Efficiency

• Optimized for 25W Input Power

• Flicker-free Dimming

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).

• 0% Minimum Dimming Level

• Quasi-resonant Second Stage with Constant-current Output

- Flyback and Buck

• Fast Startup

• Tight LED Current Regulation: Better than ±5%

• Primary-side Regulation (PSR)

• >0.9 Power Factor

Applications

• IEC-61000-3-2 Compliant

• NEMA SSL6 Compatible

•

Dimmable Retrofit LED Lamps
