LT1946EMS8#PBF

Overview

The LT1946EMS8#PBF is a synchronous boost DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.45 V to 16 V and delivers up to 1.5 A of output current. The device features a fixed switching frequency of 1.2 MHz, allowing for the use of small external components. It provides an adjustable output voltage up to 34 V and includes a shutdown function to minimize quiescent current. Packaged in an 8-lead MSOP with exposed pad, it supports operation from -40°C to +85°C.

Feature Summary

Synchronous rectification architecture for high efficiency
Integrated 1.5 A power switch
Fixed 1.2 MHz switching frequency
Shutdown capability for low power consumption

Applications

Battery-powered portable equipment
Industrial control systems
Automotive electronics
Telecommunications infrastructure

Procurement Notes

Verify the specific suffix #PBF indicates lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm the package type matches the design requirements, as variations exist within the product family. Check for any recent Product Change Notices regarding material or marking updates before finalizing procurement plans.

Selection Notes

Select this component when a compact solution is required for boosting single-cell lithium-ion battery voltages. The fixed frequency simplifies filter design compared to variable frequency alternatives. Ensure the input source can handle the peak currents drawn during startup and load transients. Evaluate thermal performance based on the PCB copper area available for the exposed pad.

Part Context

This part belongs to the LT1946 series of high-efficiency synchronous boost converters. It is designed to replace linear regulators in applications where input voltage drops below the required output level. The MSOP-8EP package offers a small footprint suitable for space-constrained designs.
