  • The NCL30081 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. This controller has integrated 5 step log dimming which allows and LED bulb to be dimming from a standard wall switch.
  • Features
  • Primary Side Sensing - No opto-coupler or secondary control circuitry
  • Wide VCC Range - Simplifies support for a broad range of LED forward voltages with one transformer design
  • Precise LED Current Regulation of ±1% typical - No need for binned forward voltage LEDS or production trimming for current accuracy
  • ~ 0.90 PF with passive valley fill - Supports US Energystar ® Integral LED Bulb and Luminaire Specifications
  • Open and shorted output protection - Easy handling of possible LED string faults
  • Secondary Diode Short Protection - Avoids overheating in fault mode
  • Shorted Current Sense Fault Detection - Robust fault handling
  • Input Line Voltage Sensing - Enhanced Regulation Accuracy across AC line variation
  • Auto-recoverable (B-version) and Latched (A-version) fault handling - Flexiblity in fault handling response
  • Wide Temperature range of -40 to 125 °C - Supports outdoor and high temperature environments
