LND060

OFFLINE LED DRIVER (Up to 277VAC)

NO INDUCTORS, FILTERs, PF>0.9, THD<25%

FEATURES

GENERAL DESCRIPTION

•

Lowest cost offline LED driver (Up to 277VAC)

No inductors, transformers or HV capacitors required

Fewer LEDs required than other direct drive

solutions

The LND060 is designed to drive one or more strings of

LEDs directly from an offline AC source. Using a Linear

Dimensions proprietary (PATENTS PENDING) switch

array, LED strings can be segmented with a combination

of series and parallel LED combinations and re-

combinations. The result is an extremely high efficiency

solution with low total harmonic distortion (THD<25%) and

high power factor (>0.9).

•

Up to 18W LED driver solution

High power factor >0.9

THD <25%

No electrolytic capacitors

No flicker, uniform brightness

Dimming:

As the LND060 connects directly to the AC line and re-

configures the LEDs to match the input voltage, it does

not require magnetics, capacitors or filtering components

as standard LED driver solutions do. This direct coupling

is also very efficient.

•

Standard TRIAC dimmer compatible

Re-organizes LEDs

Converts to 1kHz PWM dimming to eliminate

flicker at low dimming levels

•

LED recombination to optimize LED utilization, PF

and THD

The use of a proprietary switch array allows a large

number of segments and re-arrangement in serial and

parallel combinations. This overcomes the flicker, fanout,

LED utilization, low THD & poor power factor of first

generation offline direct drive schemes.

•

Current programmability for individual segments

Over current protection

Over temperature protection with automatic restart

Power package

Up to Tj=150^oC Operation

ESD protected

The LND060 is compatible with standard phase control

One percent (1%) dimming is

TRIAC dimmers.

accomplished using Linear’s proprietary patent pending

switch array, an on board charge pump, and an RMS-to-

Linear converter. When dimming the LND060 converts the

phase control signal to 1kHz PWM waveform to reduce

flicker.
