NSI50350ADT4G
Constant Current Regulator
& LED Driver
50 V, 350 mA + 10%, 11 W Package
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. 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 20% 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 AEC-Q101 standard and UL94−V0
Certified.
