Overview
SM8121A White LED Driver IC OVERVIEW The SM8121A is a high efficiency 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 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.
FEATURES I Boost-up control using PWM I 2 to 6 lights of white LED (connected in series) lighted I Output current value can be set by external resis- tors (51Ω: 9.
