LT1371CT7#PBF

Overview

The LT1371CT7#PBF is a monolithic high-power switching regulator manufactured by Analog Devices Inc., housed in a TO-263 (D2PAK) package. It operates as a current-mode DC-DC converter with a fixed switching frequency of 580 kHz. The device supports an input voltage range from 2.7 V to 30 V and delivers a maximum output current of 2.6 A. It features adjustable output voltage starting at 1.24 V, with a shutdown function for power management. Operating temperatures span from 0°C to 70°C.

Feature Summary

• Monolithic high-power switching regulator architecture
• Fixed 580 kHz current-mode control
• Integrated shutdown capability

Applications

• Point-of-load regulation

• General DC-DC conversion

Procurement Notes

Verify the specific package designation against official documentation, as datasheets may list D2PAK or similar variants. Confirm thermal requirements and pinout compatibility during integration. Ensure the supplier provides valid traceability and RoHS compliance certificates matching the manufacturer's standards for this component.

Selection Notes

Select this component for applications requiring a compact, high-current solution with a fixed high-frequency operation. The integrated current-mode control simplifies compensation compared to voltage-mode alternatives. Consider the thermal performance of the surface-mount package when designing the PCB layout for adequate heat dissipation under full load conditions.

Part Context

This part belongs to the LT137x series of switching regulators, designed for efficient power conversion in space-constrained environments. It represents a transition from older through-hole packages to surface-mount technologies while maintaining high power handling capabilities typical of the Linear Technology portfolio.
