LT3508HFE#TRPBF

Overview

The LT3508HFE#TRPBF is a dual-channel 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 independent adjustable output channels, each capable of delivering up to 1.4A. The device utilizes a fixed switching frequency between 920kHz and 1.06MHz. It is housed in a 16-lead TSSOP package with an exposed thermal pad and supports operation within a junction temperature range of -40°C to +125°C.

Feature Summary

Dual-channel architecture providing independent control over two separate output rails
Integrated high-side N-channel power switches for efficient synchronous rectification
Fixed-frequency current mode control topology for stable regulation
Exposed thermal pad design to facilitate heat dissipation from the substrate

Applications

Industrial equipment requiring multiple regulated voltage rails
Portable instrumentation powered by single-cell lithium-ion batteries
Embedded systems needing isolated or distinct power domains
Telecommunications infrastructure components

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the component matches the required operating temperature range and package dimensions for your PCB layout. Cross-reference the datasheet revision history to validate performance characteristics before finalizing procurement decisions.

Selection Notes

Select this component when a compact solution is needed for dual-output power management from a wide input voltage range. Evaluate the thermal requirements of the 16-TSSOP-EP package based on total load current and ambient conditions. Confirm that the fixed switching frequency aligns with electromagnetic interference constraints and inductor selection criteria for the target application.

Part Context

This part belongs to the LT3508 family of dual synchronous buck regulators designed for space-constrained applications. It shares architectural similarities with other members of the series but differs in package type and specific thermal handling capabilities. The HFE variant specifically denotes the tape-and-reel packaging format suitable for automated surface-mount assembly processes.
