LT3477IFE#TRPBF Description

Short technical summary and product information.

The LT3477IFE#TRPBF is a current mode, 3A DC/DC step-up converter from Analog Devices, featuring dual rail-to-rail current sense amplifiers and an internal 3A, 42V switch. It is designed for high efficiency power conversion, achieving up to 93% in typical applications.

 

Key electrical specifications include a wide input voltage range from 2.5V to 25V and a switch current capability of 3A. The switching frequency is programmable via an external resistor, ranging from 200kHz to 3.5MHz. It also includes a programmable soft-start function to limit inductor current during start-up.

 

This device is capable of driving LEDs in boost, buck-boost, or buck modes and can produce both positive and negative output voltages. It is available in a thermally enhanced 20-lead TSSOP package with an exposed pad, suitable for surface mounting.

 

The operating temperature range is -40°C to 125°C (TA). The LT3477IFE#TRPBF is RoHS3 compliant.
