Description

The SM8120A is a high efficiency step-up DC/DC converter. Due to high voltage CMOS process realizing 24V output supply as maximum value, white LED of 24 lights connected in series can be lighted. By connecting 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.
