NCL30086
Analog/Digital Dimmable
Power Factor Corrected
Quasi-Resonant Primary
Side Current-Mode
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
MARKING DIAGRAM
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
L30086x
ALYW
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.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. VDRV is the DRV clamp voltage VDRV(high) when VCC is higher than VDRV(high). VDRV is VCC otherwise.
2. This level is low enough to guarantee not to exceed the internal ESD diode and 5.5−V Zener diode. More positive and negative voltages can
be applied if the pin current stays within the −2 mA / 5 mA range.
3. This device contains ESD protection and exceeds the following tests: Human Body Model 3500 V per JEDEC Standard JESD22−A114E,
Machine Model Method 250 V per JEDEC Standard JESD22−A115B, Charged Device Model 2000 V per JEDEC Standard JESD22−C101E.
4. This device contains latch−up protection and has been tested per JEDEC Standard JESD78D, Class I and exceeds ±100 mA.
5. Recommended maximum VS voltage for optimal operation is 4 V. −0.3 V to +4.0 V is hence, the VS pin recommended range.
Table 4. ELECTRICAL CHARACTERISTICS (Unless otherwise noted: For typical values TJ = 25°C, VCC = 12 V, VZCD = 0 V,
VCS = 0 V, VSD = 1.5 V) For min/max values TJ = −40°C to +125°C, VCC = 12 V)

6. Guaranteed by Design
7. A NTC is generally placed between the SD and GND pins. Parameters RTF(start), RTF(stop), ROTP(off) and ROTP(on) give the resistance the
NTC must exhibit to respectively, enter thermal foldback, stop thermal foldback, trigger the OTP limit and allow the circuit recovery after
an OTP situation.
8. At startup, when VCC reaches VCC(on), the controller blanks OTP for more than 250 ms to avoid detecting an OTP fault by allowing the
SD pin voltage to reach its nominal value if a filtering capacitor is connected to the SD pin.
