Product Overview

The CCRKIT is a sample kit for the NSI45, NSI50 series linear constant current regulator. This regulator is a simple, economical and robust device designed to provide a cost effective solution for regulating current in LEDs. The CCR is based on self biased transistor (SBT) technology and regulates current over a wide voltage range. It is designed with a negative temperature coefficient to protect LEDs from thermal runaway at extreme voltages and currents. The CCR turns on immediately and is at 25% of regulation with only 0.5V Vak. It requires no external components allowing it to be designed as a high or low side regulator.
  • Robust power package: 460mW
  • Wide operating voltage range
  • Voltage surge suppressing − protecting LEDs
  • AEC-Q101 qualified and PPAP capable, UL94−V0 certified
  • SBT (self biased transistor) technology
  • Negative temperature coefficient
