EUP2589 12 String White LED Driver With Boost Controller DESCRIPTION FEATURES 3µA shutdown current The EUP2589 is a high power and high efficiency 12 strings in parallel and up to 18 LEDs per boost controller with 12-channel current sinker which string is ideal for large LCD backlighting applications. External PWM or DC Voltage Dimming EUP2589 uses current mode, fixed frequency Control architecture which can clamp the inductor peak current Output voltage up to 65V each cycle. The switching frequency is programmable Wide Input voltage range 4.5V to 28V by an external frequency setting resistor. It drives an Better than 1.5% LED Current Regulation external MOSFET to boost up the output voltage from Accuracy Between Strings a 4.5V to 28V input supply. The EUP2589 regulates Boost Switching frequency can be programmed the current in each LED string to the programmed by external resistor value set by an external current setting resistor. The Multiple Fault Protections EUP2589 current matchi [ … ]
