NJW4605-T - I2C Controlled White LED Driver

Description

The NJW4605 is a high efficiency multiple strings white LED driver for backlight.

This device is composed 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.

Features

  • variable switching frequency between 300kHz and 1MHz. When an abnormal LED lighting occurs, the FLT Pin sends out signals notifying the abnormality to the controller such as CPU. The NJW4605 operates over a wide supply voltage range from 6V to 30V, and operating temperature is up to 105ºC. This very wide operating temperature range makes the IC ideal for medium sized LCD backlights, such as car navigations, note PC, and appl.

NJW4605-T 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 composed 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 notifying the abnormality to the controller such as CPU.
