Overview
The LT1375HVCS8#TRPBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5 V to 30 V and provides an adjustable output voltage from 2.42 V to 25.8 V. The device supports a maximum switch current of 1.5 A and features a fixed switching frequency of 500 kHz. It utilizes a SOIC-8 surface-mount package and includes shutdown functionality. The component is designed for high efficiency at high frequencies using a special high-speed bipolar process.
Feature Summary
- High-efficiency operation at high switching frequencies due to specialized bipolar process technology
- Supports both Buck and SEPIC topologies for flexible power conversion applications
- Integrated shutdown pin for low-power standby modes
Applications
- Battery-powered systems requiring efficient step-down regulation
- Industrial control systems operating within wide input voltage ranges
- Portable equipment utilizing single-supply architectures
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the HV designation corresponds to the extended 30 V input capability rather than standard variants. Ensure compatibility with the SOIC-8 footprint during PCB layout. Cross-reference the manufacturer's latest datasheet for any updates regarding material declarations or marking changes.
Selection Notes
Select this component when an adjustable output voltage is required within a 5 V to 30 V input window. It is suitable for designs needing up to 1.5 A of switch current without external synchronous rectification. Consider the 500 kHz frequency for balancing component size and efficiency. Verify thermal requirements for the SOIC-8 package under maximum load conditions.
Part Context
This part belongs to the LT1375/LT1376 family of high-frequency step-down regulators. These devices are engineered for applications demanding high efficiency across a wide input voltage range. The family distinguishes itself through the use of a high-speed bipolar process, enabling superior performance compared to standard CMOS alternatives in similar form factors.
Replacement Considerations
LT1375IS8#PBF is listed as a parameter-equivalent alternative. Note that the IS8 variant may differ in input voltage specifications or temperature ranges compared to the HV version. Verify topology support and current ratings before substitution.
