NCL30080
Product Preview
Quasi-Resonant Primary
Side Current-Mode
Controller for LED Lighting
The NCL30080 is a PWM current mode controller targeting isolated
flyback and non−isolated constant current topologies. The controller
operates in a quasi−resonant mode to provide high efficiency. Thanks
to a novel control method, the device is able to precisely 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 wide V
CC
range simplifies the design process and
allows a single design to support a wide LED forward voltage range. A
robust suite of safety protection is built in to simplify the design. This
device is specifically intended for very compact space efficient
designs

Pin Description
Connected to the auxiliary winding; this pin detects the core reset event.
The controller ground
This pin monitors the primary peak current
The current capability of the totem pole gate drive (+0.3/−0.5 A) makes it suit-
able to effectively drive a broad range of power MOSFETs.
This pin is connected to an external auxiliary voltage.
This pin observes the HV rail and is used in valley selection. This pin also
monitors and protects for low mains conditions.
