Analog Devices Inc. LT3478EFE is a versatile DC-DC LED driver IC featuring a True Color PWM™ series design. This component provides a single output with a step-down (buck) and step-up (boost) topology, capable of delivering up to 4.5A through its internal switch. The device supports PWM dimming for precise light control and operates with an input voltage range of 2.8V to 36V, with an output voltage capability of up to 42V. The switching frequency is adjustable from 200kHz to 2.25MHz. Designed for surface mounting, it is supplied in a 16-TSSOP-EP package with an exposed pad for enhanced thermal performance. Typical applications include display backlighting across industries such as automotive and consumer electronics. The operating temperature range is -40°C to 125°C (TJ).
