The LT3477IFE#TRPBF is a current mode, 3A DC/DC step-up converter from Linear Technology, equipped with dual rail-to-rail current sense amplifiers. It supports a wide input voltage range from 2.5V to 25V and an internal 3A, 42V switch, offering high efficiency power conversion up to 93%.
This converter is capable of driving LEDs in boost, buck-boost, or buck modes. The switching frequency is programmable via an external resistor, ranging from 200kHz to 3.5MHz. It also features a programmable soft-start function to manage inductor current during startup. The design allows for both positive and negative output voltages, making it suitable for boost, inverting, SEPIC, and Flyback topologies.
The LT3477IFE#TRPBF is available in a thermally enhanced 20-lead (4mm × 4mm) QFN and a 20-lead TSSOP package. Its dual current sense amplifiers have a typical setpoint of 100mV, adjustable independently via IADJ1 and IADJ2 pins. This makes it a versatile solution for constant-voltage and constant-current applications, including high power LED drivers and DSL modems.
