General 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
◾ Current consumption less than or equal to 2µA at
shut-down
◾ Low ripple output owing to a complementary
charge pump circuit
◾ Over current protection when VOUT short to GND.
◾ Soft start function
◾ Mounting various protection functions such as
current overload limiter and thermal shut-down
circuit
APPLICATIONs
This driver is applicable for various fields such as
mobile phones, portable game machines and
appliances.
