Analog Devices Inc. LT3478IFE is a versatile DC/DC regulator IC featuring True Color PWM™ technology. This single-output device supports both step-down (buck) and step-up (boost) topologies, enabling a wide output voltage range up to 42V. It integrates a 4.5A switch for efficient LED driving, with PWM dimming capabilities for precise light control. Operating frequencies can be adjusted from 200kHz to 2.25MHz, offering flexibility in design. The LT3478IFE is housed in a 16-TSSOP-EP package with an exposed pad for enhanced thermal performance. It is suitable for applications requiring precise LED illumination, such as backlighting in automotive and industrial displays. The operating temperature range is -40°C to 125°C (TJ), and it requires a supply voltage between 2.8V and 36V.
