Beschreibung
This IC is white LED driver IC with PWM step-upDC/DC converter that can boost max 41V and currentdriver that can drive max 30mA. The wide andprecision brightness can be controlled by externalPWM pulse. This IC has very accurate current drivers,and it has few current errors between each strings. So,it will be helpful to reduce brightness spots on the LCDpanel. Small package is suited for saving space.
Eigenschaften
High accuracy & good matching current drivers 8ch(MAX30mA/ch) Integrated 50V power Nch MOSFET Soft Start function Drive up to 11 LEDs in series, 8 strings in parallel Rich safety functions・Over-voltage protection・External SBD open detect / Output Shortprotection・Over current limit・CH Terminal open / GND short protect・CH over voltage protect / LED short protect・Thermal shutdown・UVLO Analog Brightness Control
Typische Anwendungen
- LCD equipments, Backlight of Notebook PC, net book, monitor, light, Portable DVD playerlight source etc
