Switching at a fixed 1 MHz, the part allows a small external inductor and ceramic output capacitor, keeping the total bill-of-materials footprint compact for space-constrained backlight assemblies. PWM dimming is supported directly on the enable pin, giving the system designer a straightforward brightness-control interface without an external PWM generator. ## Input supply range and thermal envelope The supply input accepts 4.5 V to 24 V. Packaged in a 16-pin WFQFN with an exposed pad (3 mm × 3 mm), the device relies on the PCB copper pour under the pad for thermal dissipation. It remains a current-production choice for new designs requiring a six-channel boost LED driver with PWM dimming.","metaTitle":"TPS61181ARTET Boost Regulator, 6-Channel LED Driver","metaDescription":"Texas Instruments TPS61181ARTET DC-DC boost regulator, 6 outputs, 38V max, PWM dimming, 1MHz switching.
