NJU6043

PWM WHITE LED DRIVER

ꢀ General Description

ꢀ Package

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..
