BD1604MUV, BD1604MVV
No.11040EBT23
●Description
This LSI is a 4 white LED driver for small LCD backlight. At the charge pump type, the number of external devices is
minimized.
●Features
1) 4 parallel LED driver is mounted.
2) The LED current can be controlled via an external resistance.
3) Maximum current is 120mA (30mA × 4).
4) LED1 to LED4 can be turned on or off via an external control pin.
5) The relative current accuracy among LEDs (LED1 to LED4) is 3%.
6) Automatically transition to each mode (×1.0, ×1.5, ×2.0).
7) High efficiency (90% or more at maximum) is achieved.
8) Various protection functions such as output voltage protection function, current overload limiter and thermal shutdown
circuit are mounted.
●Applications
This driver provides for:
- Backlight using white LED
- Auxiliary lights for mobile phone cameras and simplified flash
