Overview
The LT1371HVCSW#TRPBF is a high-voltage switching regulator manufactured by Analog Devices Inc. It supports multiple topologies including Buck, Boost, Cuk, Flyback, Forward, and SEPIC configurations. The device operates with an input voltage range from 2.7 V to 30 V and delivers a maximum output current of 3 A. It features a fixed switching frequency of 500 kHz and adjustable output voltage starting at 1.245 V. The component is housed in a 20-SOIC package and functions within a temperature range of 0°C to +125°C.
Feature Summary
- Supports versatile power conversion topologies including buck, boost, flyback, forward, and SEPIC.
- Capable of handling high input voltages up to 30 V for demanding applications.
- Integrates a 500 kHz switching frequency to optimize external component size.
Applications
- Industrial power supply systems
- Telecommunications equipment
- Battery-powered devices requiring step-up or step-down regulation
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the HV variant designation matches the required input voltage specifications. Ensure compatibility with the 20-SOIC footprint during PCB layout. Cross-reference the manufacturer datasheet for updated RoHS compliance status before finalizing procurement orders.
Selection Notes
Select this component for designs requiring flexible topology support beyond standard buck or boost converters. The wide input voltage range accommodates various source conditions. Consider thermal management requirements due to the 3 A switch current capability. Verify that the 500 kHz frequency aligns with electromagnetic interference constraints in the target application environment.
Part Context
This part belongs to the LT1371 family of high-voltage switching regulators. It shares core architecture with variants like LT1371CR#PBF but differs in package type and shipping format. The series is designed for general-purpose DC-DC conversion tasks requiring robust performance across diverse operating conditions.
Replacement Considerations
LT1371CR#PBF serves as a pin-compatible alternative in tube packaging. LT1371ISW#PBF offers similar functionality in a standard SOIC package. Verify electrical parameters match exactly before substituting any related model numbers.
