LT1371HVIR#PBF

Overview

The LT1371HVIR#PBF is a high-efficiency switching regulator from Analog Devices, operating at a fixed 500 kHz frequency. It supports multiple topologies including Buck, Boost, Cuk, Flyback, Forward, and Inverting configurations. The device accepts an input voltage range of 2.7 V to 30 V and delivers up to 3 A output current. It features adjustable output voltage with a shutdown function. Packaged in a DDPAK-7 surface-mount format, it operates within a temperature range of 0°C to +125°C.

Feature Summary

• Supports versatile DC-DC conversion topologies including buck, boost, and inverting circuits
• Integrates a high-current switch capable of delivering up to 3 A
• Operates at a fixed 500 kHz switching frequency for efficient design
• Includes a shutdown pin for power management control

Applications

• Industrial power supply systems requiring flexible topology options
• Battery-powered equipment utilizing boost or buck conversion
• Inverting power rails for analog signal processing circuits
• General-purpose DC-DC conversion modules

Procurement Notes

Verify the specific suffix 'IR' against the official datasheet to confirm package type and temperature rating. Ensure compatibility with the required topology as this component supports multiple configurations. Confirm lead times and availability status directly with authorized distributors, as stock levels may vary. Validate RoHS compliance documentation prior to final procurement decisions.

Selection Notes

Select this component when a single IC must support multiple converter topologies such as buck, boost, or inverting. It is suitable for designs requiring a 3 A switch current capability and operation up to 30 V input. Consider the DDPAK-7 package for thermal performance in space-constrained applications. Verify that the fixed 500 kHz frequency aligns with EMI requirements and inductor selection constraints.

Part Context

This part belongs to the LT1371 family of high-efficiency switching regulators. It shares core architecture with variants like the LT1371CR but differs in package and temperature specifications. The HV designation indicates extended voltage handling capabilities compared to standard versions. It serves as a flexible solution for designers needing multi-topology support without using discrete components.

Replacement Considerations

LT1371CR#PBF is a parameter-equivalent alternative available in a different package configuration.
