NSI50350AST3G
Constant Current Regulator
& LED Driver
50 V, 350 mA + 10%, 5.8 W Package
The linear constant current regulator (CCR) is a simple, economical
and robust device designed to provide a costâeffective solution for
regulating current in LEDs. The CCR is based on SelfâBiased
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 lowâside regulator. The high anodeâcathode
voltage rating withstands surges common in Automotive, Industrial
and Commercial Signage applications. The CCR comes in thermally
robust packages and is qualified to AECâQ101 standard and
UL94âV0 Certified.
Also available in DPAK: NSI50350ADT4G.
