White LED Driver IC

The SM8121A is a high efciency Step-up DC-DC Converter Due to high voltage CMOS process realizing 25V output supply as maximum value, 2 to 6 lights of white LED connected in series CAN be lighted. By con- necting in series, current variation among LED is eliminated. Current value sent to white LED CAN be set by external resistors. In addition, brightness CAN also be adjusted by control to FB pin or CE pin. By Seiko NPC Corp.
