Datasheet 1-Channel 190mA Charge Pump White LED Driver with 1-wire Serial Interface BD1603NUV General Description Key Specifications The high-power (large current output) type LED driver is a Operating power supply voltage range: 2.7V to 5.5V white LED driver best suited for applications that require Oscillator frequency: 238 or 642kHz(Typ.) the large current. It is equipped with output voltage and Operating temperature range: -30 to +85 oscillation frequency switch functions to flexibly cope Output Voltage: 190mA 4.5V(Typ.) with a wide variety of applications. Because output 150mA 5.0V(Typ.) voltage is fixed at 4.5V or 5.0V, it is also applicable to applications except the LED driver. Package W(Typ.) x D(Typ.) x H(Max.) VSON010V3030 3.00mm x 3.00mm x 1.00mm Features Current consumption less than or equal to 2A 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 VSON010V3030 3.00mm x 3.00mm x 1.00mm Lineup Parameter BD1603NUV Applications Up to 10 LEDs Number of LEDs This driver is applicable for various fields such as (Up to maximum load current) mobile phones, portable game machines and Boost magnification 2 fixed (4.5V or 5.0VOUTput) appliances.
