Overview
The LT1374IT7#PBF is a monolithic Buck switching regulator manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 500 kHz and supports an input voltage range from 5 V to 25 V. The device provides an adjustable output voltage between 2.42 V and 21.5 V, delivering a switch current of 4.5 A. It features a low static current of 20 uA and a shutdown function. The component is housed in a TO-220-7 package with straight leads, designed for through-hole mounting, and functions within a junction temperature range of 0°C to +125°C.
Feature Summary
- Integrates a high-current 4.5 A power switch for efficient step-down conversion
- Supports both Buck and SEPIC topologies for flexible circuit design
- Includes a shutdown pin for enhanced power management capabilities
Applications
- Industrial control systems requiring regulated DC power
- Distributed power supply architectures
- Battery-powered equipment needing efficient voltage regulation
Procurement Notes
Verify the specific suffix IT7 corresponds to the TO-220-7 through-hole package configuration. Confirm RoHS compliance status via official documentation before integration. Ensure thermal management solutions are adequate for the operating environment given the through-hole form factor.
Selection Notes
Select this part when a robust through-hole solution is required for high-current applications. The 500 kHz frequency allows for compact passive components compared to lower-frequency alternatives. Verify that the input voltage does not exceed the 25 V maximum limit during operation.
Part Context
This component belongs to the LT1374 series of high-efficiency switching regulators. It shares core electrical characteristics with other variants like the LT1374CT7#PBF but differs in packaging and temperature rating specifications defined by the manufacturer's coding system.
Replacement Considerations
LT1374CT7#PBF serves as a direct functional substitute within the same series, offering identical electrical performance in a compatible through-hole package.
