Datasheet Summary
I2C Controlled White LED Driver IC for Backlight
GENERAL DESCRIPTION
The NJW4605 is a high efficiency multiple strings white LED driver for backlight. This device is posed with 3-channel constant current drivers, step-up switching regulator that can drive up to 24pcs LED.
Each constant current driver is able to supply maximum current of 80mA per channel. And the accuracy of supply current between each driver is ±2.0% (max.) controlled by high precision current control circuit. The NJW4605 can control luminance by PWM signal input, and also Features variable switching frequency between 300kHz and 1MHz.
When an abnormal LED lighting occurs, the FLT Pin sends out signals...
