资 源 简 介
The linear constant current regulator (CCR) is a simple, economical and robust device designed to provide a cost−effecTIve soluTIon for regulaTIng current in LEDs (similar to Constant Current Diode, CCD). 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 35% of regulation with only 0.5 V Vak. It requires no external components allowing it to be designed as a high or low−side regulator. The high anode-cathode voltage rating withstands surges common in Automotive, Industrial and Commercial Signage applications. The CCR comes in thermally robust packages and is qualified to be UL94−V0 certified.
