Brightness control is handled through PWM dimming, and the switching frequency can be set between 600 kHz and 2 MHz, letting the designer optimise between inductor physical size and switching losses. The internal power switch is included, so the external BOM stays compact. The input supply range spans 4.2 V to 24 V, covering single-cell Li-ion through industrial 24 V rails. The 24-VFQFN package with exposed pad (4x4 mm body) requires a thermal land pattern on the PCB to conduct heat away from the die.","metaTitle":"TI TPS61185RGET DC-DC Boost Regulator, 8-Channel LED Driver","metaDescription":"Texas Instruments TPS61185RGET step-up regulator drives 8 LED channels at 25 mA each, 38V output.
