The LT3508 is a dual monolithic current mode PWM step-down DC/DC converter with internal power switches, designed to 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 the use of small inductors and ceramic capacitors for a compact solution. The converters synchronize to a single oscillator and run in anti-phase, 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.
Protection features include cycle-by-cycle current limit, frequency foldback, and thermal shutdown. The low shutdown current of less than 2μA is beneficial for battery-powered systems. The LT3508 is available in a 4mm x 4mm 24-pin QFN package, suitable for surface mount applications.
Key applications include automotive systems, DSP power supplies, wall transformer regulation, and DSL/cable modems.
The input voltage range is 3.7V to 36V.
Each output can deliver up to 1.4A.
The switching frequency is adjustable from 250kHz to 2.5MHz.
The output voltage is adjustable down to 800mV.
The shutdown current is less than 2μA.
It is available in a 24-VFQFN exposed pad package.
Surface mount.
