Dimming is controlled via a PWM signal on the dedicated dimming input, which modulates the LED current without shifting the output voltage — a standard approach for maintaining consistent colour temperature across the brightness range. ## 1 MHz switching — inductor and ripple trade-off The 1 MHz oscillator lets the designer pick a small inductor, typically 4.7 µH to 10 µH in a 2.0 mm or 2.5 mm footprint, keeping the total solution height low for slim backlight assemblies. The trade-off is higher switching losses than a 500 kHz part, but the efficiency curve peaks in the 10 mA to 100 mA LED current range where most backlight strings operate. ## Package and thermal land pattern Without the vias, the junction temperature rises above the 85°C ambient ceiling at full load. The pad is electrically connected to GND, so the via pattern also serves as a low-impedance ground return for the switching loop. It is not specified for under-hood or engine-bay environments where ambient exceeds 85°C.","metaTitle":"TPS61061DRBRG4 Boost LED Driver, 18.5 V Output, 1 MHz","metaDescription":"Texas Instruments TPS61061DRBRG4 is a PWM-dimmable step-up DC-DC regulator for backlight applications.
