LT1672CS8#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1672CS8#PBF is a high voltage step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 4.5V to 60V and provides an adjustable output voltage starting at 1.24V. The device delivers up to 300mA of switch current and integrates a 60V NPN power transistor. Packaged in an 8-lead SOIC, it features cycle-by-cycle current limiting, thermal shutdown, and soft-start capabilities for robust operation in industrial applications.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Integrated 60V NPN power transistor eliminates external component requirements
• Cycle-by-cycle current limiting protects against short circuits and overloads
• Thermal shutdown circuitry ensures device safety during overheating events
• Soft-start function limits inrush current during power-up sequences

Instrumentation, Op Amps, Buffer Amps Applications

• Industrial process control systems requiring isolated or non-isolated DC-DC conversion
• Battery-powered equipment needing efficient step-down regulation from higher voltage sources
• Distributed power architectures in telecommunications infrastructure
• General-purpose high-voltage buck converter designs for embedded systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix and package variant against official manufacturer documentation before procurement. Ensure that the ordering information matches the exact electrical characteristics and thermal performance required for the target application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when input voltages exceed standard low-voltage regulator limits but remain below 60V. Consider the fixed internal frequency and lack of synchronization if timing alignment with other system clocks is critical. Evaluate thermal dissipation requirements based on the expected load current and ambient temperature conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1672 family of high voltage switching regulators designed by Linear Technology, now part of Analog Devices. The CS8 suffix denotes the specific 8-lead SOIC plastic package configuration. The #PBF indicates lead-free compliance and RoHS adherence according to manufacturer standards.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official manufacturer cross-reference guides for verified substitutes. Direct replacements must match the 60V input rating, 300mA current capability, and SOIC-8 package footprint while maintaining equivalent protection features.
