Preliminary EUP2990 6 String White LED Driver with Boost Converter DESCRIPTION The EUP2990 is a high efficiency boost regulator with 6 channel current sinker which is ideal for media size LCD backlighting applications. The device with integrated 2.5A/43V power MOSFET uses current mode architecture and drives six strings in parallel and supports up to 10 pieces of LEDs per string. The switching frequency is programmable by an external frequency setting resistor. The EUP2990 regulates the current in each LED string to the programmed value set by an external current setting resistor. The EUP2990 current matching can achieve ±2%.
