Texas Instruments LM36274 Backlight Driver & LCD Bias Power IC Chip

The Texas Instruments LM36274 Display Power Driver IC Chip is a factory-standard, highly integrated dual-purpose display semiconductor engineered explicitly for motherboard-level diagnostics and micro-soldering restoration on smartphone logic boards. This advanced integrated circuit (IC) combines two critical power generation roles on a single die: driving multi-channel White LED (WLED) backlight string arrays and regulating independent positive and negative LCD bias supply paths (±4V to ±6.5V) required by screen glass substrates to display images. It features built-in 11-bit dimming resolution capabilities controlled via a high-speed I2C serial interface or logic-level Pulse Width Modulation (PWM) tracking lines, providing optimal system conversion efficiencies up to 92%.
