Overview
The LT1376HVIS#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It integrates a 1.5A power switch, oscillator, and control logic into an 8-SOIC package. The device operates with an input voltage range of 5V to 25V and supports a fixed switching frequency of 500kHz. It features adjustable output voltage capability and includes shutdown functionality. The component is rated for operation within a temperature range of -40°C to +125°C TJ.
Feature Summary
- Integrates a high-current 1.5A internal power switch for compact design
- Supports both Buck and SEPIC topologies for flexible circuit configurations
- Includes built-in shutdown pin for low-power standby modes
Applications
- Battery-powered portable equipment requiring efficient step-down conversion
- Industrial control systems utilizing wide input voltage ranges
- General-purpose DC-DC conversion in space-constrained PCB layouts
Procurement Notes
Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics match your schematic requirements. Ensure the ordering part number corresponds exactly to the required package type and temperature grade before finalizing procurement orders.
Selection Notes
Select this component when a single-output buck regulator with integrated high-current switching is required. The 500kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the thermal performance of the SOIC package meets the application's heat dissipation needs under maximum load conditions.
Part Context
This part belongs to the LT1376 family of switching regulators designed for cost-sensitive and space-constrained applications. The series offers a balance of performance and simplicity by integrating most necessary control circuitry on-die, reducing the bill of materials and board area required for implementation.
