LT1676CN8#PBF

Overview

The LT1676CN8#PBF is a wide input range, high-efficiency buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 8V to 35V and provides an adjustable output voltage from 2.21V to 31.5V. The device delivers a switch current of 1.2A at a fixed switching frequency of 100kHz. It supports both positive and negative output configurations and utilizes an 8-pin PDIP package for through-hole mounting.

Feature Summary

• Supports buck, boost, and flyback topologies for versatile power conversion
• Enables positive or negative output voltage configurations
• Operates at a fixed 100kHz switching frequency

Applications

• General DC-DC step-down conversion
• Negative voltage generation circuits
• Flyback converter designs

Procurement Notes

Verify the specific suffix CN8 indicates the PDIP package variant distinct from SOIC versions. Confirm RoHS compliance status via the manufacturer's declaration. Check lead times as availability may be limited. Ensure the ordering part number matches the required through-hole package type for PCB integration.

Selection Notes

Select this component when a single IC must support multiple topologies including buck, boost, and flyback. It is suitable for applications requiring either positive or negative regulated outputs from a single supply. The through-hole PDIP package aids in prototyping or specific mechanical constraints where surface mount is not preferred.

Part Context

This part belongs to the LT1676 family of high-efficiency switching regulators. It shares core functionality with other variants like the LT1676CS8 but differs in package style. The family is designed for wide input voltage ranges and flexible output configurations in power management systems.

Replacement Considerations

LT1676CS8#PBF offers identical electrical performance in an 8-SOIC surface-mount package.
