LT3508EUF#TRPBF Description

Short technical summary and product information.

The LT3508EUF#TRPBF is a dual monolithic step-down switching regulator from Analog Devices, designed to provide two independent 1.4A outputs. It operates with a wide input voltage range of 3.7V to 36V, making it suitable for various power sources like automotive batteries and industrial supplies. The device supports adjustable switching frequencies from 250kHz up to 2.5MHz, allowing for the use of small inductors and capacitors.

 

Key features include anti-phase switching to reduce input ripple current, independent tracking and soft-start circuits for controlled power supply sequencing, and a power good signal output. Cycle-by-cycle current limiting, frequency foldback, and thermal shutdown provide protection against output shorts. The regulator is available in a compact 24-QFN (4x4mm) surface mount package.

 

Applications for the LT3508EUF#TRPBF include automotive systems, DSP power supplies, wall transformer regulation, and DSL/cable modems. Its adjustable output capability down to 800mV and precise undervoltage lockout further enhance its design flexibility.
