Overview
The LT1371HVIR#TRPBF is a monolithic switching regulator from Analog Devices, housed in a D2PAK-7 package. It supports multiple topologies including boost, buck, Cuk, flyback, forward, and inverting configurations. The device operates with an input voltage range of 2.7 V to 30 V and delivers up to 3 A of output current. It features a fixed 500 kHz switching frequency and adjustable output voltage. The IC includes shutdown functionality and operates within a temperature range of 0°C to +125°C.
Feature Summary
- Supports versatile power conversion topologies such as boost, buck, Cuk, flyback, forward, and inverting circuits.
- Integrates a high-efficiency 3 A switch for robust current handling capabilities.
- Features a fixed 500 kHz internal oscillator to minimize external component requirements.
- Includes a dedicated shutdown pin for effective power management control.
Applications
- Industrial power supply systems requiring flexible topology options
- Battery-powered equipment utilizing boost or inverting configurations
- Telecommunications infrastructure power distribution networks
- Automotive electronics operating within specified voltage ranges
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the HV variant rating matches your input voltage requirements, as standard versions differ. Ensure the D2PAK-7 thermal pad connection is properly designed for heat dissipation at maximum load conditions. Cross-reference the datasheet for exact pinout assignments to prevent PCB layout errors during integration.
Selection Notes
Select this component when a single IC must support multiple converter topologies without changing parts. The 500 kHz frequency offers a balance between efficiency and passive component size. Consider the 3 A switch limit against peak load demands. Verify that the 30 V maximum input voltage exceeds your system's highest potential supply level under all operating conditions.
Part Context
This part belongs to the LT1371 family of high-efficiency switching regulators. It shares architectural similarities with other members like the LT1371CR but differs in package type and temperature rating. The HV designation typically denotes extended voltage handling capabilities compared to standard variants within the same product line.
Replacement Considerations
LT1371CR#PBF serves as a pin-compatible alternative in a different package format. LT1370HV series devices offer higher current capacity but may require different external component values. Verify compatibility regarding switching frequency and control loop compensation before substitution.
