MAX1698AEUB+T

The MAX1698AEUB+T represents a high accuracy and cost effective 5 channel, linear LED driver solution. The device includes five channel LED driver blocks, each capable of driving 6 to 42V LED (matrix) strings. The MAX1698AEUB+T is intended for controlling LED strings for LCD display lighting, LCD contrast adjustment and LED backlight applications.

A feature of the MAX1698AEUB+T is the two sets of independent LED driver channels. This allows two different LED string configurations to be used depending on the application. The two sets of independent LED driver channels can be tied together to drive a single LED string.

The MAX1698AEUB+T is an application specific, configurable linear LED driver designed for LCD applications. It integrates five separate Lighting control blocks each with an independent temperature control loop. The configurable timing control and programmable current sink combinational logic enable a cost effective design for matrix LED applications.

The MAX1698AEUB+T features a programmable current sink that regulates the output current level using both linear and constant current modes. The linear current mode is intended for LCD contrast adjustment applications, while the constant current mode is intended for LED applications. The linear current sink is ideal for controlling power outputs over a wide operating temperature range without the need for additional temperature control circuitry.

The MAX1698AEUB+T also features a temperature control loop. The loop is optimized for controlling the output current to maintain a constant light output during varying ambient temperatures and cabinet influences. The temperature control loop allows the LED driver to efficiently regulate the LED string currents while compensating for LED light deterioration.

The LED driver also features adjustable current limiting, under voltage lockout and programmable voltage tracking and voltage dimming. A programmable thermistor temperature sensing circuit is also available.

The MAX1698AEUB+T is designed to drive low voltage LED strings, providing fast over current protection and adjustable current limit. It is intended specifically for LCD applications with low voltage LED strings. The device is intended for use with a minimum of 6V and a maximum of 42V LED strings. The MAX1698AEUB+T is a cost effective, low noise, efficient, and high accuracy linear LED driver.

In summary, the MAX1698AEUB+T is a 5 channel, low voltage linear LED driver application specific solution for LCD applications. The device is designed to provide fast over current protection and adjustable current limit, and is capable of driving 6 to 42V LED (matrix) strings. The device features programmable current sink, current limiting, under voltage lockout, programmable voltage tracking and voltage dimming, and a programmable thermistor temperature sensing circuit.
