BCR602 - Linear LED IC Controller

BCR602 - Linear LED IC Controller

Infineon's BCR602 is a linear LED controller IC regulating the LED current by means of an external driver transistor. BCR602 supports the use of NPN bipolar transistors and N-channel MOSFETs to cover a wide LED current and power range up to several hundred mA. The LED current is fully scalable by dimensioning an external current sense resistor.

BCR602 suppresses the voltage ripple of the power supply by driving a constant LED current for flicker-free light output.

The LED current can be dimmed by resistors as well as analog voltages connected to the multi-function input-output (MFIO) pin.

The embedded hot-plug protection allows users to plug in and plug out any LED load during operation without damaging the LEDs.

It features overtemperature and overvoltage protection for reliable operation and safety of LEDs.

  • Overtemperature protection feature reduces the LED current by 30 percent of the nominal current if the junction temperature threshold is exceeded
  • Adjustable overvoltage protection provides feedback to the primary side by the optocoupler in case the supply voltage exceeds the threshold
  • 60 V capable, constant current linear controller
  • Supports NPN bipolar transistors or N-channel MOSFETs
  • 100 Hz/120 Hz supply voltage ripple suppression
  • Hot plug protection
  • Multifunction I/O pin for analog dimming
  • Rset functionality to set LED current
  • Overvoltage and overtemperature protection
  • The control loop minimizes the voltage overhead and power dissipation of the external driver transistor. The voltage overhead can be adjusted according to the application needs
  • Linear control up to 60 V with highly precise LED current
  • Protection features enabling long lifetime of LEDs
  • Providing high light quality and analog dimming
