Per-channel current is rated at 60 mA — that is the continuous limit through the integrated switch; the actual LED current is set by the external sense resistor, so the designer chooses the brightness point below that ceiling. The 1.8 V to 6 V supply input range covers single-cell Li-ion (3.6 V nominal) and 5 V USB rails alike. Housed in an 8-VDFN exposed pad package (3×3 mm body, SON footprint), the part relies on the exposed thermal pad for heat sinking. Without that thermal relief, the 60 mA output at high ambient (85°C) pushes the junction near the limit.","metaTitle":"TPS61043DRBR Boost LED Driver, 1 MHz, 16.9 V, 60 mA","metaDescription":"TI TPS61043DRBR DC-DC boost regulator with integrated switch, PWM dimming, 1 MHz switching, 16.9 V output at 60 mA.
