LED Drivers for LCD Backlights
Backlight LED Driver
for Small LCD Panels (Charge Pump Type)
BD1603NUV
No.11040EBT20
●Description
The high-power (large current output) type LED driver is a white LED driver best suited for applications that require the large current.
It is equipped with output voltage and oscillation frequency switch functions to flexibly cope with a wide variety of applications.
Because output voltage is fixed at 4.5V or 5.0V, it is also applicable to applications except the LED driver.
●Features
1) Selectable 4.5V or 5.0V output voltage
2) 190mA output (at Vo=4.5V)
3) 150mA output (at Vo=5.0V)
4) Oscillation frequency switching (238kHz or 642kHz)
5) Current consumption less than or equal to 2µA at shut-down
6) Low ripple output owing to a complementary charge pump circuit
7) Over current protection when VOUT short to GND.
8) Soft start function
9) Mounting various protection functions such as current overload limiter and thermal shut-down circuit
10) Small VSON package
●Applications
This driver is applicable for various fields such as mobile phones, portable game machines and appliances.
