LT1375HVCS8#PBF

Overview

The LT1375HVCS8#PBF is a monolithic buck switching regulator from Analog Devices, housed in an SOIC-8 package. It integrates a high-current switch and control circuitry for efficient DC-to-DC conversion. The device operates with an input voltage range of 5 V to 30 V and delivers an adjustable output voltage up to 1.5 A. It features a fixed switching frequency of 500 kHz, enabling the use of compact external components. The unit supports shutdown functionality and functions within a temperature range of 0°C to +125°C.

Feature Summary

• Integrates a 1.5A power switch with oscillator and logic circuits on a single die
• Supports adjustable output voltage configuration via external feedback network
• Operates at a high 500kHz switching frequency to minimize passive component size
• Includes shutdown pin capability for enhanced power management flexibility

Applications

• Battery-powered portable equipment requiring efficient step-down regulation
• Industrial systems needing robust power supply solutions within wide input ranges
• Embedded applications utilizing surface-mount technology for space-constrained designs

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm the exact electrical characteristics and package variant. Ensure that the procurement channel provides valid traceability and authenticity certificates. Confirm RoHS compliance status through the manufacturer's latest material declaration. Cross-reference the part number with current datasheets to validate availability and lead times before finalizing orders.

Selection Notes

Select this component when a high-efficiency buck converter with an adjustable output is required for inputs up to 30V. The integrated 1.5A switch suits moderate load applications without external MOSFETs. Consider the 500kHz frequency for balancing efficiency and component size. Verify thermal performance requirements against the SOIC-8 package limitations for the intended operating environment.

Part Context

This part belongs to the LT1375 series of monolithic buck regulators. It shares architectural similarities with other members like the LT1375IS8-5#PBF but differs in output configuration and input voltage handling capabilities. The series is designed for applications demanding high efficiency and compact footprint in power management systems.

Replacement Considerations

LT1375HVIS8#PBF is a documented parameter-equivalent alternative.
