Dimmable Power Factor Corrected LED Driver NCL30486 The NCL30486 is a power factor corrected flyback controller targeting isolated constant current LED drivers. The controller operates in a quasiresonant mode to provide high efficiency. Thanks www.onsemi.com 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, its biasing and for an optocoupler. 9 The device is highly integrated with a minimum number of external 1 components. A robust suite of safety protection is built in to simplify SOIC9 the design. This device is specifically intended for very compact space CASE 751BP efficient designs and supports analog and digital dimming with two dedicated dimming inputs control ideal for Smart LED Lighting MARKING applications.

Typical Application Schematic for NCL30486 PIN FUNCTION DESCRIPTION NCL30486 Pin N Pin Name Function Pin Description 1 ADIM Analog dimming This pin is used for analog control of the output current. Applying a voltage varying between V and V will dim the output current from 0% to 100%. DIM(EN) DIM100 2 COMP OTA output for CV loop This pin receives a compensation network to stabilize the constant voltage loop 3 ZCD Zero crossing Detection This pin connects to the auxiliary winding and is used to detect the core reset event. V sensing This pin also senses the auxiliary winding voltage for accurate output voltage control aux 4 CS Current sense This pin monitors the primary peak current. 5 GND The controller ground 6 DRV Driver output The drivers output to an external MOSFET 7 VCC Supplies the controller This pin is connected to an external auxiliary voltage. 8 PDIM PWM dimming This pin is used for PWM dimming control. An optocoupler can be connected directly to the pin if the PWM control signal is from the secondary side 9 NC creepage 10 HV High Voltage sensing This pin connects after the diode bridge to provide the startup current and internal high voltage sensing function. www.onsemi.com 2
