■ 제품사양

Output Current = 20mA Input Voltage = 9 ??35 V AC or DC Input Voltage = dc Dimming Operation = PWM Application = Computer Display, LCD Backlighting, Notebook, TV
패키지 = HTSSOP-B Number of Pins = 40 Maximum Output Voltage = 9.1V Minimum Output Voltage = 8.9V
Current 등급 = 16mA Power Dissipation = 4.7W BD9422EFV is a high efficiency driver for white LEDs and designed for large LCD panel. This IC is built-in high current drive and high responsibility type 6ch LED drivers and 1ch boost DCDC converter. BD9422EFV has some protect function against fault conditions, such as the over-voltage protection (OVP), LED OPEN and SHORT protection, the over current limit protection of DCDC (OCP). Therefore BD9422EFV is available for the fail-safe design over a wide range output voltage.6ch Constant LED drivers, available 400mA drive per 1ch. Constant current accuracy ±1.8% (IC only) Each 6ch external PWM inputs can control independent dimming. Current Analogue (linear) dimming by VREF 1ch boost controller with current mode (external FET) Several protection functions DCDC part : OCP/OVP/UVLO/TSD LED driver part :OPEN,SHORT detection SHORT detection voltage is set by LSP terminal. Error detection output FAIL terminal inside (normal=Open, error=Drain) Master/Slave mode inside
