Description
BD9470AEFV and BD9470AFM are high efficiency driver for white LED.
They are designed for large sized LCD.
BD9470AEFV and BD9470AFM are built-in DCDC converter that supply appropriate voltage for light source.
Features
- 6ch LED constant current driver.
- LED maximum output current 250mA.
- Individual PWM dimming modulation allowed for
LEDs.
- ±2% LED current accuracy (when each LED is set
to 130mA).
- Built-in LED feedback voltage automatic adjustment
circuit according to LED current.
- Built-in start-up circuit independent of PWM light
modulation.
- built-in VOUT FB voltage maintenance function
when PWM=Low（0%）.
- Built-in LED current stabilization circuit while
scanning operation.
