BD9470AEFV規(guī)格書詳情
General 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.
BD9470AEFV and BD9470AFM are also built-in
protection function for abnormal state such as OVP:
over voltage protection, OCP: over current limit
protection of DCDC, SCP: short circuit protection, open
detection of LED string.
Thus they are used for conditions of large output
voltage and load conditions.
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
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 is performed
Built-in VOUT discharge circuit while shutdown
Built-in LED protection (OPEN / SHORT protection)
Individual detection and individual LED OFF for
both open and short circuit
Adjustable LED short-circuit protection threshold
PWM-independent LED protection
VOUT over voltage protection (OVP) and reduced
voltage protection (SCP) circuit
Built-in failure indication function
Built-in ISET pin short-circuit protection circuit
