Overview
The LT1370HVIT7#PBF is a high-efficiency, high-frequency current mode switching regulator manufactured by Analog Devices Inc. It supports multiple topologies including Boost, Buck, Cuk, Flyback, Forward, and Inverting configurations. The device features an adjustable output voltage with a maximum switch voltage rating of 42V and delivers up to 6A of switch current. It operates within an input voltage range of 2.7V to 30V and switches at a frequency of 500kHz. The component utilizes a TO-220-7 package for through-hole mounting and functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Supports versatile circuit topologies including boost, buck, cuk, flyback, forward, and inverting configurations.
- Delivers high efficiency performance with a 500kHz switching frequency.
- Capable of handling high output currents up to 6A with adjustable output voltage.
- Includes shutdown functionality for power management control.
Applications
- Industrial power supply systems
- Distributed power architectures
- Battery-powered equipment requiring efficient step-up or step-down conversion
Procurement Notes
Verify the specific suffix IT7 corresponds to the TO-220-7 through-hole package variant when sourcing. Confirm that the HV designation aligns with the required 42V switch voltage rating for your application. Ensure compatibility with the 500kHz switching frequency regarding external component selection. Check for RoHS compliance status as indicated in official documentation before finalizing procurement orders.
Selection Notes
Select this component when high current capability up to 6A is required alongside flexible topology options. The wide input voltage range suits applications powered by single-cell lithium batteries or varying DC sources. Consider the thermal requirements associated with the TO-220-7 package for adequate heat dissipation. Verify that the operating temperature range meets the environmental conditions of the intended deployment scenario.
Part Context
This part belongs to the LT1370 series of high-frequency switching regulators designed for general-purpose power conversion. It shares core architectural features with other variants in the family but differs in package type and temperature grade. The LT1370 series is known for its current-mode control architecture which provides fast transient response and inherent cycle-by-cycle current limiting protection.
Replacement Considerations
LT1370CR#PBF: Offers similar electrical specifications but uses a DDPAK-7 surface mount package and has a commercial temperature range (0°C to 70°C). LT1370HVIR#PBF: Provides equivalent performance in a TO-263-8 surface mount package with a commercial temperature range.
