LT1376CS#PBF

Overview

The LT1376CS#PBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5 V to 25 V and delivers a maximum output current of 1.5 A. The device features a fixed internal switching frequency of 500 kHz, enabling the use of small external components. It provides an adjustable output voltage and includes a shutdown feature for power management. The component is housed in an SOIC-16 surface-mount package and is rated for operation within a temperature range of 0°C to +125°C.

Feature Summary

• Integrates a high-efficiency buck converter topology capable of delivering up to 1.5 A of continuous output current.
• Features a fixed 500 kHz switching frequency to minimize passive component size while maintaining stable regulation.
• Includes a dedicated shutdown pin to reduce quiescent current consumption during standby modes.

Applications

• Point-of-load regulation for industrial control systems
• Power supply stages in embedded computing platforms
• Battery-powered equipment requiring efficient step-down conversion

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and electrical characteristics. Ensure compatibility with required thermal management solutions given the operating temperature limits. Cross-reference ordering information directly with Analog Devices or authorized distributors to validate availability and authenticity before procurement.

Selection Notes

Select this component when a compact solution is needed for converting higher input voltages down to lower levels at moderate currents. The fixed frequency operation simplifies filter design compared to variable frequency regulators. Consider the SOIC-16 footprint constraints and thermal dissipation requirements relative to the expected load profile and ambient conditions.

Part Context

This part belongs to the LT1376 series of monolithic buck converters from Analog Devices. The series is designed for applications requiring high efficiency and minimal external component count. Variants within the family may differ in input voltage ranges, package styles, or output configurations, necessitating careful selection based on specific circuit requirements.

Replacement Considerations

LT1376CS8#TRPBF: Offers identical electrical performance but utilizes an SOIC-8 package instead of SOIC-16. Verify pinout compatibility and physical footprint differences before substitution.
