The LT3508EFE#PBF is a dual monolithic step-down switching regulator from Analog Devices, designed to generate two 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.
This device features adjustable output voltage down to 800mV and an adjustable switching frequency from 250kHz to 2.5MHz. The converters can be synchronized and run in anti-phase to reduce input ripple current. Its high operating frequency allows for the use of small inductors and ceramic capacitors.
Key features include independent tracking, soft-start circuits, and a power good signal for each regulator, which simplifies power supply sequencing. Cycle-by-cycle current limit, frequency foldback, and thermal shutdown provide protection against output shorts. The LT3508EFE#PBF is available in a 16-TSSOP-EP package with exposed pad and surface mount mounting type.
Applications for this regulator include automotive systems, DSP power supplies, wall transformer regulation, DSL and cable modems, and PCI Express.
