LT1961IMS8E#TRPBF

Overview

The LT1961IMS8E#TRPBF 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 delivers a maximum output current of 1.5A and utilizes a fixed switching frequency of 1.25MHz. It is housed in an 8-lead MSOP package with an exposed pad and supports an operating temperature range of -40°C to 125°C.

Feature Summary

Integrates a power switch for high-efficiency step-up conversion
Features low noise architecture suitable for sensitive applications
Includes internal compensation to minimize external component count
Offers thermal shutdown protection for system reliability

Applications

Portable instrumentation powered by single-cell batteries
RF front-end modules requiring clean supply voltages
Industrial sensor interfaces needing boosted rail generation
Automotive electronics utilizing 12V or 24V systems

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing components. Confirm the manufacturer designation as Analog Devices Inc. or Linear Technology to ensure authenticity. Check for RoHS compliance status relevant to your manufacturing region requirements before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require boosting low input voltages to higher levels efficiently. Consider the 1.25MHz frequency for balancing component size against transient response needs. Ensure the selected inductor can handle the peak currents associated with the 1.5A output capability under minimum input voltage conditions.

Part Context

This part belongs to the LT1961 family of micropower step-up regulators designed for battery-powered applications. It shares the core topology with other variants in the series but differs in packaging and shipping configuration. The IMS8EPBF designation specifies the surface-mount package type used for compact board layouts.
