Description
BCR601 is a linear LED controller IC regulating the LED current by means of an external driver transistor. BCR601 supports use of NPN bipolar transistors and NMOS MOSFETs to cover a wide LED current and power range. BCR601 provides feedback to the primary side via an optocoupler to control the output voltage of the primary side converter, e.g. a flyback. The control loop minimizes the voltage overhead and power dissipation of the external driver transistor. The voltage overhead can be adjusted by external configuration according to application needs. BCR601 suppresses the voltage ripple of the power supply driving a constant LED current for better light quality. The LED current is fully scalable by dimensioning an external current sense resistor. The embedded hot plug protection allows plug in and plug out of the LED load during operation reducing LED current overshoots and related LED life time degradations. The adjustable overvoltage protection will provide feedback to the primary side by the optocoupler in case the supply voltage exceeds the threshold. The overtemperature protection will dim the LED current if the BCR601 junction temperature threshold is exceeded. In this case the LED current will be reduced to 30% of the nominal current. Once the junction temperature drops below the temperature hysteresis nominal LED current is resumed. The BCR601 is a perfect fit for LED applications by combining small form factor with low cost. Through its higher integration, BOM savings and ensuring long lifetime of LEDs, this controller has many advantages compared to discrete solutions.
