White LED Driver IC

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 ●Boost-up control using PWM\n●2 to 6 lights of white LED (connected in series) lighted\n●Output current value can be set by external resistors\n(51Ω: 9.8mA, 33Ω: 15.2mA, 24Ω: 20.8mA)\n●Brightness adjustable by control to FB pin or CE pin\n●Current variation among LED decreased by high precision\n●Hi;
