Description
BD9202EFS is the LED driver IC which loads the step-up DCDC controller and the constant electric current driver of 8ch.
Features
- 1)8ch constant electric current driver built-in
Largest drive electric current 150mA/CH.
- 2 10bit gradation (1024 stages) modulated light is possible by register setting To input the standard CLK of PWM from outside is possible (BCT_SYNC_IN terminal) Because it is high output resisting pressure (60V), the multi-stage connection of LED is p ossi b le Detecting abnormal mode with LED opening detection 2)Step-up DCDC controller built-in 3) UVLO function 4) 4 line serial interface 5) HTSSOP-A4.
