Constant Current Regulator
& LED Driver
45 V, 25 mA + 15%, 460 mW 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 patent-pending
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 0.5 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.
