The LT3508EUF#TRPBF is a dual, current mode PWM step-down DC/DC converter manufactured by LT. It integrates two power switches capable of delivering 1.4A output current each. The device operates over a wide input voltage range from 3.7V to 36V, making it suitable for various power sources like automotive batteries and industrial supplies.
Key features include an adjustable switching frequency from 250kHz to 2.5MHz, which allows for the use of small inductors and ceramic capacitors. The converters can be synchronized and operate in anti-phase to reduce input ripple current. Each regulator has independent tracking, soft-start, and power good circuits, facilitating power supply sequencing. The output voltage is adjustable down to 800mV.
Protection features include cycle-by-cycle current limit, frequency foldback, and thermal shutdown. A low shutdown current of less than 2μA is beneficial for battery-powered applications. The LT3508EUF#TRPBF is available in a 4mm x 4mm 24-pin QFN package or a 16-pin thermally enhanced TSSOP package, both designed for surface mounting.
Applications for this regulator include automotive systems, DSP power supplies, wall transformer regulation, DSL and cable modems, and PCI Express power.
