LT1176CSW#PBF

Overview

The LT1176CSW#PBF is a switching regulator IC manufactured by Analog Devices Inc. It supports Buck, Boost, and Flyback topologies with adjustable output voltage ranging from 2.21V to 31.5V. The device features an integrated switch capable of handling 1.2A current and operates at a fixed switching frequency of 100kHz. It accepts an input voltage range of 8V to 35V and provides positive or negative output configurations. The component is housed in a 8-SOIC (0.295", 7.50mm Width) surface-mount package and is rated for operation within a temperature range of 0°C to 70°C.

Feature Summary

Supports multiple converter topologies including buck, boost, and flyback configurations
Integrates a high-current switch for efficient power conversion
Allows flexible output configuration for both positive and negative voltages

Applications

General-purpose DC-DC power supply designs
Battery-powered equipment requiring step-up or step-down regulation
Industrial control systems utilizing isolated or non-isolated power stages

Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and check for any recent production change notices that may affect pinout or electrical characteristics. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a versatile single-inductor solution for buck, boost, or flyback applications is required. Consider the 1.2A internal switch limit and 100kHz fixed frequency when designing passive components. Evaluate thermal performance within the specified operating temperature range and ensure the SOIC package fits the available PCB footprint constraints.
