It integrates the switching FET internally and delivers up to 30 mA per channel at a regulated output voltage up to 17.5 V. PWM dimming input is provided directly, so the host processor or backlight controller can vary brightness without an external PWM transistor. ## 850 kHz switching — inductor sizing and EMI At this frequency the fundamental ripple sits below 1 MHz, which helps pass conducted emission limits without a complex input filter. The 5.5 V absolute max means a 5 V rail is safe — no external clamp needed. The 0.50 mm pitch BGA requires a 2-layer or 4-layer board with micro-vias for fan-out — plan the PCB stack-up before committing the layout.","metaTitle":"LM3508TL/NOPB LED Driver IC – TI Boost Regulator, 30 mA","metaDescription":"Texas Instruments LM3508TL/NOPB DC-DC boost regulator for LED backlight. 850 kHz switching, PWM dimming, 17.5 V max output, 30 mA per channel.
