White LED Driver IC

The SM8122A 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. Since the SM8122A has an over voltage protection circuit built-in, it dispenses with the existing external ZD (zener diode). Besides, the switching frequency of the SM8122A is higher (2.0MHz) than the existing product SM8121A , so that it CAN respond to lower inductance value. By Nippon Precision Circuits Inc, (NPC)
