Controller IC for Dimmable Offline LED Lamps

General Description

Features

The MAX16841 is an LED driver for AC line (100V, 120V,

220V, and 230V AC) input lamps. It features proprietary

control of the input current that allows lamps to dim

smoothly from full to zero light intensity, while providing

active power factor correction (PFC). It is a very flexible

product that can be used in isolated (e.g., flyback) and

nonisolated (e.g., buck) configurations. The conventional

use of an optocoupler in isolated configurations can be

avoided in MAX16841-based designs.

S Smooth Dimming with Leading-Edge (Triac) and

Trailing-Edge Dimmers

S Active Power Factor Correction

S Nonisolated (e.g., Buck) and Isolated

(e.g., Flyback) Topologies

S Universal 90V to 264V AC Input Range

S Constant Frequency-Control Scheme Maximizes

Efficiency at High and Low AC Line Voltage

The constant frequency-control technique of the

device allows maximization of the conversion efficien-

cy at both low and high AC line by operating at the

conduction mode that minimizes total conduction and

switching losses.

S Constant Power Control with No Need for

Optocouplers

S Very-Low Quiescent Current

S Output Open and Short Protection

S Thermal Shutdown

The device can be configured for universal input (90V to

264V AC) dimmable applications, allowing the design of an

LED lamp that can be operated and dimmed worldwide.

S Available in an 8-Pin SO Package

This device can be used without electrolytic capacitors,

thus maximizing the lamp lifetime. In this case, the LED

current is a rectified sinusoid with a frequency that is

twice the AC line frequency.

Ordering Information appears at end of data sheet.

Typical Operating Circuits appear at end of data sheet.

The device also features thermal shutdown, current limit,

open LED protection, and V

The MAX16841 is available in an 8-pin SO package and
