LT1946AEMS8E#TRPBF

Overview

The LT1946AEMS8E#TRPBF is a synchronous boost and SEPIC DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.45V to 16V and provides an adjustable output voltage up to 35V. The device integrates a 1.5A switch and supports a switching frequency of 2.7MHz. It is housed in an 8-lead MSOP package with an exposed pad, suitable for surface mount applications within an operating temperature range of 0°C to 70°C.

Feature Summary

Supports both boost and SEPIC topologies for flexible power conversion
Integrates a high-current 1.5A internal switch
Features adjustable output voltage capability

Applications

Battery-powered portable electronics requiring voltage step-up
Systems utilizing single-cell lithium-ion or alkaline batteries
Applications necessitating SEPIC topology for varying input voltages

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the A-grade designation matches thermal and electrical requirements. Ensure the 8-MSOP-EP footprint aligns with PCB layout specifications. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status and availability constraints.

Selection Notes

Select this component when designing circuits that require either boost or SEPIC functionality from a single IC. The 2.7MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 1.5A switch current rating meets peak load demands. Consider the 0°C to 70°C operating range against environmental conditions.

Part Context

This part belongs to the LT1946 family of synchronous regulators. It shares architectural similarities with other members like the LT1946, which operates at a lower 1.2MHz frequency. The EMS8E package variant ensures compatibility with standard surface mount assembly processes while providing thermal management through the exposed pad design.
