Infineon Technologies BCR420UE6327
The BCR 420U E6327 / BCR 421U E6327 provides a low-cost solution for driving 0.25 W LEDs with a typical LED current of 75 mA to 150 mA. The BCR 420U E6327 / BCR 421U E6327 can be operated with a supply voltage of more than 40 V considering the voltage drop of the LED load which reduces the output voltage to the maximum rating of the driver.| Part No. | BCR420UE6327 |

GENERAL DESCRIPTION
Internal breakdown voltage is higher than 40 V which is the maximum voltage the LED driver can sustain when the output is directly connected to supply voltage. The enable pin of BCR 420U E6327 can withstand a maximum voltage of 40 V which can be increased adding a series resistor in front of the enable pin reducing the voltage at the enable pin below 40 V.
