MAX16826ATJ+T

The MAX16826ATJ+T is a programmable, four-string HB LED driver with output-voltage optimization and fault detection in 32 pin TQFN package. The MAX16826 high-brightness LED (HB LED) driver is designed for backlighting automotive LCD displays and other display applications such as industrial or desktop monitors and LCD televisions. The MAX16826 integrates a switching regulator controller, a 4-channel linear current sink driver, an analogue to digital converter (ADC) and an I2C interface. The IC is designed to withstand automotive load dump transients up to 40V and can operate under cold crank conditions. The MAX16826 contains a current-mode PWM switching regulator controller that regulates the output voltage to the LED array. The switching regulator section is configurable as a boost or SEPIC converter and its switching frequency is programmable from 100KHz to 1MHz.
