Additional Infomation About Product

NCL30083 Dimmable Quasi-Resonant Primary Side Current-Mode Controller for LED Lighting with Thermal Fold-back www.onsemi.com The NCL30083 is a PWM current mode controller targeting isolated flyback and nonisolated constant current topologies. The controller operates in a quasiresonant mode to provide high efficiency. Thanks 8 8 to a novel control method, the device is able to precisely regulate a 1 1 constant LED current from the primary side. This removes the need Micro8 SOIC8 for secondary side feedback circuitry, biasing and an optocoupler. DM SUFFIX D SUFFIX CASE 846A CASE 751 The device is highly integrated with a minimum number of external components. A robust suite of safety protection is built in to simplify the design. This device is specifically intended for very compact space MARKING DIAGRAM efficient designs. It supports step dimming by monitoring the AC line 8 and detecting when the line has been toggled onoffon by the user to reduce the light intensity in 5 steps down to 5% dimming.

PIN FUNCTION DESCRIPTION Pin No Pin Name Function Pin Description 1 SD Thermal Foldback Connecting an NTC to this pin allows reducing the output current down to 50% and shutdown of its fixed value before stopping the controller. A Zener diode can also be used to pullup the pin and stop the controller for adjustable OVP protection 2 ZCD Zero Crossing Detection Connected to the auxiliary winding, this pin detects the core reset event. 3 CS Current sense This pin monitors the primary peak current 4 GND The controller ground 5 DRV Driver output 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. 6 VCC Supplies the controller This pin is connected to an external auxiliary voltage. 7 VIN BrownOut This pin observes the HV rail and is used in valley selection. This pin also Input voltage sensing monitors and protects for low mains conditions. 8 SS SoftStart A capacitor connected to ground select the softstart duration. www.onsemi.com 2
