BD9488F is a high efficiency driver for white LEDs and designed for large LCDs. This IC is built-in a boostDCDC converters that employ an array of LEDs as the light source. BD9488F has some protect function against fault conditions, such as the over-voltage protection(OVP), the over current limit protection of DCDC (OCP),LED over current protection (LEDOCP), the open detection of LED string. Therefore BD9488F is available for the fail-safe design over a wide range output voltage.
Current mode DCDC converter
Vout discharge circuit as shutdown
LED protection circuit (OPEN protection, LED OCP protection)
LED protect detection as small PWM dimming signal
Over-voltage protection (OVP) for the output voltage.
Adjustable soft start time constant
The wide range of analog dimming 0.2V-3.5V
The built-in transformation circuit from pulse to DC
2 PWM dimming signal
The UVLO detection for the input voltage of the power stage
FAIL logic output
