Quality Control: Learn More
The Analog Devices Inc. LT3478IFE-1 is a versatile DC-DC regulator featuring a single output designed for LED driving applications. This component leverages True Color PWM™ technology for precise dimming control. It supports both step-down (buck) and step-up (boost) topologies, offering flexibility in power conversion. The internal switch can handle up to 4.5A, and the output voltage can reach 42V, with input voltage ranging from 2.8V to 36V. Operating with a switching frequency between 200kHz and 2.25MHz, the LT3478IFE-1 is suitable for demanding backlight applications. It is supplied in a 16-TSSOP-EP package for surface mounting and operates within an ambient temperature range of -40°C to 125°C.
