GENERAL DESCRIPTION

The ACT801 are LED driver ICs based on Active-

Semi's Patented Active Direct DriveTM Technology

and Patent-Pending Active Valley FillTM that

adaptively drives a string of variable-weighted LED

segments up to 8W directly from an AC line voltage

with very few total components. By adaptively

modulating the variable-segment-weighted LED

string voltage to match the varying AC line voltage,

the Active Direct DriveTM Technology results in the

ACT801 having highest efficiency, high power

factor (> 0.90), and low total harmonic distortion.

The high efficiency and high performance make the

ACT801 ideal for advanced energy saving solid

state lighting applications and eases thermal

design.

With very few external components, the ACT801

ensures high reliability and long life time for LED-

based luminaire designs. In addition, the IC protects

the LEDs from over current, and over temperature

conditions. The ACT801 are optimized to operate at

100-120VAC and non-dimmable application up to

8W.

The ACT801 also incorporate Active-Semi's Patent-

Pending Active Valley FillTM Technology for

maintaining smooth light output for the full AC cycle,

enabling the LEDs to operate without noticeable

flicker or strobe light motion effects. These devices

drive the LED string without high frequency

switching.

The ACT801 are available in the SOP-16EP

package.
