BD9489F規(guī)格書詳情
General Description
BD9489F is a high efficiency driver for white LEDs and is designed for large LCDs. BD9489F has a boost DCDC converter that employs an array of LEDs as the light source.
BD9489F has some protect functions against fault conditions, such as over-voltage protection (OVP), over current limit protection of DCDC (OCP), LED OCP protection, and Over boost protection (FBMAX). Therefore it is available for the fail-safe design over a wide range output voltage.
Features
■ DCDC converter with current mode
■ As PWM=L, the retaining function of Vout, FB voltage
■ VOUT discharge function at shutdown
■ LED protection circuit (Over boost protection, LED OCP protection)
■ Over-voltage protection (OVP) for the output voltage Vout
■ Adjustable soft start
■ Adjustable oscillation frequency of DCDC
■ Wide range of analog dimming 0.2V to 3.0V
■ UVLO detection for the input voltage of the power stage
Applications
■ TV, Computer Display, LCD Backlighting
