LT3508IUF Description

Short technical summary and product information.

The LT3508IUF from Analog Devices is a dual current mode PWM step-down DC/DC converter. It features internal power switches capable of generating two 1.4A outputs. The wide input voltage range of 3.7V to 36V makes it suitable for various power sources, including automotive batteries and industrial supplies.

 

This regulator supports an adjustable switching frequency from 250kHz to 2.5MHz and can be synchronized over the full frequency range. It utilizes anti-phase switching to reduce ripple current and is designed to use small inductors and ceramic capacitors. The output voltage is adjustable down to 800mV.

 

Available in small 4mm x 4mm 24-pin QFN or 16-pin thermally enhanced TSSOP surface mount packages, the LT3508IUF is AEC-Q100 qualified for automotive applications. It also includes independent tracking, soft-start, and power good circuits to ease supply sequencing.
