nsic2020jb: led driver, constant current regulator, 120 v, 20 ma, ±15%, for a/c off-凯发登录


rev. 1 (153kb)



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 45% 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 120 v anode-cathode voltage rating is designed to withstand the high peak voltage incurred in a/c offline applications. the high anode-cathode voltage rating withstands surges common in automotive, industrial and commercial signage applications.
