The LT3508EUF#TRPBF is a dual current mode PWM step-down DC/DC converter from Analog Devices, featuring internal power switches that can generate two 1.4A outputs. Its wide input voltage range of 3.7V to 36V makes it suitable for various power sources, including automotive batteries and industrial supplies.
This device operates with a programmable switching frequency up to 2.5MHz, allowing for the use of small inductors and ceramic capacitors. Both converters synchronize to a single oscillator and run with opposite phases, which helps reduce input ripple current. Each regulator includes independent tracking and soft-start circuits, and generates a power good signal when its output is in regulation, simplifying power supply sequencing.
The LT3508EUF#TRPBF offers protection features such as cycle-by-cycle current limit, frequency foldback, and thermal shutdown. It is available in a compact 4mm x 4mm 24-pin QFN package, suitable for surface mount applications. The low shutdown current of less than 2μA is beneficial for battery-powered systems.
The input voltage range is 3.7V to 36V.
Each regulator can deliver up to 1.4A.
The switching frequency is adjustable from 250kHz to 2.5MHz.
The output voltage can be adjusted down to 800mV.
The shutdown current is typically 2µA.
It is available in a 24-VFQFN exposed pad package for surface mount.
