Overview
LV5026MC is a High voltage LED drive controller which drives LED current up to 3A with external MOSFET.
LV5026MC is realized very simple LED circuits with a few external parts. It corresponds to various wide dimming
controls including the TRIAC dimming control.
Note) This LV5026MC is designed or developed for general use or consumer appliance. Therefore, it is NOT permitted
to use for automotive, communication, office equipment, industrial equipment.

Note1) Absolute maximum ratings represent the values which cannot be exceeded for any length of time.
Note2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high
voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
