PWM dimming on the enable pin gives clean, flicker-free brightness control without pulling the output down. ## Package and temperature rating The single-output boost topology with internal switch reduces external BOM count to one inductor, one diode, one capacitor, and a couple of resistors.","metaTitle":"TPS61040DDCR DC-DC Boost Regulator, 28 V Output, 1 MHz","metaDescription":"Texas Instruments TPS61040DDCR step-up DC-DC regulator, 28 V output, 350 mA switch, 1 MHz PWM dimming.
