LT3508EFE#PBF

Overview

The LT3508EFE#PBF is a dual synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.7V to 36V and provides two adjustable output channels, each capable of delivering up to 1.4A. The device integrates high-side and low-side N-channel power switches, eliminating the need for external Schottky diodes. It supports a switching frequency range from 920kHz to 1.06MHz, allowing for optimized inductor size and efficiency. The minimum adjustable output voltage is 0.8V, with a maximum of 35.28V per channel.

Feature Summary

Integrates dual high-side and low-side N-channel power switches for compact design
Supports wide input voltage range suitable for various power sources
Features adjustable switching frequency for flexibility in component selection

Applications

Industrial point-of-load regulation
Telecommunications infrastructure power distribution
Embedded systems requiring multiple voltage rails

Procurement Notes

Verify the specific suffix PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the package type matches the 16-SSOP footprint requirements of your PCB layout. Ensure the operating temperature range aligns with your system's thermal environment specifications.

Selection Notes

Select this component when dual isolated or non-isolated outputs are required from a single input source. Consider the 1.4A current limit for load requirements and the 36V maximum input rating. Evaluate the switching frequency setting against available inductor options to balance efficiency and physical size constraints.

Part Context

This part belongs to the LT3508 family of dual synchronous buck regulators. It shares architectural similarities with other high-voltage step-down converters but is distinct in its dual-output configuration and integrated switch ratings. It serves as a solution for applications needing efficient voltage conversion from higher bus voltages.
