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..
