NCL30082: Dimmable Quasi-Resonant Primary Side Current Mode Controller for LED Lighting with thermal foldback

Description: The NCL30082 is a PWM current mode controller targ...
  • The NCL30082 is a PWM current mode controller targeting isolated flyback and non-isolated buck-boost 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 robust suite of safety protection is built in to simplify the design. The device supports analog/digital dimming and thermal foldback. While the NCL30082 has integrated fixed overvoltage protection, the designer has the option to program a lower OVP level.
  • Features
  • Primary Side Sensing - No Optocoupler or secondary control circuitry required
  • Wide VCC Range - Simplifies support for range of LED forward voltages
  • Precise LED Current Regulation of ± 1% typical - No need for binned LEDs for forward voltage or production line trimming for accuracy
