LT1961IMS8E#PBF

Overview

The LT1961IMS8E#PBF is a step-up switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 25V and provides an adjustable output voltage from 1.2V to 35V. The device supports a maximum output current of 1.5A and utilizes a fixed switching frequency of 1.25MHz. It is housed in an 8-pin MSOP EP package and is rated for automotive applications within a temperature range of -40°C to +125°C.

Feature Summary

Integrates a high-efficiency synchronous boost converter topology
Features internal power switch capable of delivering 1.5A load current
Supports wide input voltage range suitable for single-cell battery sources

Applications

Automotive electronics systems
Portable devices powered by single-cell lithium-ion batteries
Industrial control equipment requiring regulated higher voltages

Procurement Notes

Verify the complete part number including suffixes against official Analog Devices documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status and specific automotive qualification requirements prior to procurement. Cross-reference datasheet revisions to validate pinout compatibility and electrical specifications for your design implementation.

Selection Notes

Select this component when designing circuits requiring a compact solution for boosting low input voltages to higher levels. It is appropriate for applications needing up to 1.5A output current with minimal external component count. Consider the 1.25MHz switching frequency for balancing efficiency and passive component size in space-constrained designs.

Part Context

This part belongs to the LT1961 family of step-up regulators designed for automotive and industrial use. It shares the core architecture with other variants in the series but differs in packaging and specific thermal characteristics. The MSOP EP package provides enhanced thermal performance compared to standard plastic packages, supporting reliable operation in demanding environments.
