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.
