BD9488F is a high efficiency driver for white LEDs and designed for large LCDs. This IC is built-in a boost DCDC 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. 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
