Preliminary www.DataSheet4U.com NJU6043 PWM WHITE LED DRIVER General Description The NJU6043 is a high efficiency white LED driver with low input voltage. It is a PWM type DC/DC converter. The typical output current is 20 mA. Because the switching frequency is about 1 MHz, so tiny parts such as inductor and capacitor can be used to save space. The NJU6043 is suitable for portable electronic applications such as cell phone, digital still camera, or PDA etc.. Package Features Drive up to 5 white LEDs in series IOUT = 20mA High Efficiency 87% Over Voltage Protection Circuit(OVP)19.5V Shut-down circuit Switching Frequency 1MHz (PWM) Under-voltage lockout circuit (UVLO) Low profile inductor and capacitor Operation Voltage VDD = 2.5 ~ 5.
