LT1370HVIR#TRPBF

Overview

The LT1370HVIR#TRPBF is a high-efficiency switching regulator from Analog Devices, housed in a D2PAK-7 (TO-263-8) surface-mount package. It supports multiple topologies including Buck, Boost, Cuk, Flyback, Forward, and SEPIC configurations. The device operates with an input voltage range of 2.7V to 42V and delivers up to 6A of switch current. It features a fixed 500kHz switching frequency and adjustable output voltage starting at 1.245V. The unit functions within a temperature range of 0°C to +70°C and includes shutdown capability.

Feature Summary

Supports versatile power conversion topologies including buck, boost, and inverting configurations
Integrates a high-current internal switch for efficient power delivery
Provides flexible input voltage handling across a wide operational range
Includes shutdown functionality for system power management

Applications

Industrial distributed power systems
Battery-powered equipment requiring step-up or step-down conversion
Telecommunications infrastructure power supplies
Embedded control systems with variable input sources

Procurement Notes

Verify the suffix TRPBF indicates tape-and-reel packaging distinct from tube variants. Confirm the HV designation aligns with the required 42V maximum input specification. Ensure the D2PAK-7 thermal pad soldering requirements are met during assembly. Cross-reference the datasheet for specific ordering information regarding the reel quantity and lead-free compliance status.

Selection Notes

Select this component when a single IC must support multiple converter topologies such as buck, boost, or SEPIC. The 6A switch current rating suits applications demanding moderate to high power density. The wide input range accommodates various battery chemistries and unregulated sources. Verify that the 500kHz frequency meets EMI constraints and efficiency targets for the specific design.

Part Context

This part belongs to the LT1370 family of monolithic switching regulators. It shares core architecture with variants like LT1370CR but differs in input voltage limits and packaging. The HV variant specifically extends the maximum input capability compared to standard versions. It serves as a flexible building block for custom power supply designs requiring topology versatility.
