Controller for LED Lighting
www.onsemi.com
The NCL30086 is a power factor corrected flyback controller
targeting isolated and non−isolated “Smart−dimmable” constant
current LED drivers. The controller operates in a quasi−resonant mode
to provide optimal efficiency. The current control algorithm supports
SOIC−10
CASE 751BQ
flyback, buck−boost, and SEPIC topologies. Thanks to a novel control
method, the device is able to tightly regulate a constant LED current

from the primary side. This removes the need for secondary side
feedback circuitry, biasing and an optocoupler.
The device is highly integrated with a minimum number of external

components. A robust suite of safety protection is built in to simplify
G
the design. This device is specifically intended for very compact space
efficient designs and supports analog and PWM dimming with a
dedicated dimming input intended to control the average LED current. To
ensure reliable operation at elevated temperatures, a user configurable
current foldback circuit is also provided. The NCL30086 is housed in
the SOIC10 which has the same body size as a standard SOIC8.

Pin Description
This pin is used for analog or PWM dimming control. An analog signal that can be
varied between VDIM0 and VDIM100 or a PWM signal can be used to adjust the
LED current.
Connected to the auxiliary winding, this pin detects the core reset event.
This pin monitors the input voltage rail for:
Power Factor Correction
Valley lockout
Brownout Detection
This pin receives a filtering capacitor for power factor correction. Typical values
ranges from 1 − 4.7 mF.
Connecting an NTC to this pin allows the user to program thermal current fold-
back threshold and slope. A Zener diode can also be used to pull−up the pin and
stop the controller for adjustable OVP protection.
This pin monitors the primary peak current.
Controller ground pin.
The driver’s output to an external MOSFET
This pin is the positive supply of the IC. The circuit starts to operate when VCC
exceeds 18 V and turns off when VCC goes below 8.8 V (typical values). After
start−up, the operating range is 9.4 V up to 26 V (VCC(OVP) minimum level).
