参考设计 / 应用评估套件

 
    • Evaluation Board - BD18353EFV-EVK-001

    • This Evaluation Board was developed for ROHM’s LED Driver BD18353EFV-M. BD18353EFV-M is a 1ch LED Controller. High side current detection amplifier is built-in. PWM dimming duty can be freely set with built-in PWM generation circuit. PWM dimming realizes by driving an external P-ch MOSFET. Outputs abnormal LED status to the FAULT_B pin. Two systems of analog dimming are built-in. High precision 3.0V output power supply for analog dimming and PWM dimming setting is built-in.
