Overview
The LT1373HVCS8#TRPBF is a high-efficiency switching regulator from Analog Devices, operating at a fixed 250 kHz frequency. It supports multiple topologies including Buck, Boost, Cuk, Flyback, Forward, and Inverting configurations. The device accepts an input voltage range of 2.7 V to 30 V and delivers a switch current of 1.5 A. It features adjustable output voltage capability with a minimum setting of 1.245 V. Designed for robust performance, it operates within a temperature range of 0°C to +125°C junction temperature. The component utilizes low supply current technology, drawing only 1 mA of quiescent current, making it suitable for power-sensitive applications requiring versatile DC-DC conversion in an 8-pin SOIC package.
Feature Summary
- Supports versatile converter topologies including buck, boost, Cuk, flyback, forward, and inverting configurations
- Features low supply current consumption for enhanced energy efficiency
- Provides high-efficiency switching regulation with adjustable output voltage capabilities
Applications
- Portable battery-powered equipment requiring efficient step-up or step-down conversion
- Industrial control systems utilizing various DC-DC topology requirements
- Automotive electronics operating within standard voltage ranges
Procurement Notes
Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the HV variant designation matches your input voltage requirements up to 30 V. Ensure compatibility with the 8-SOIC surface-mount footprint during PCB layout. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the 250 kHz switching frequency aligns with your electromagnetic interference constraints.
Selection Notes
Select this component when multiple converter topologies are needed from a single IC. Consider the 1.5 A switch current limit for load requirements. Evaluate the 2.7 V to 30 V input range against your source voltage. The adjustable output allows flexibility for various rail voltages. Compare thermal performance in the SOIC package against higher current alternatives if heat dissipation is critical.
Part Context
This part belongs to the LT1373 family of switching regulators known for low supply current and high efficiency. It serves as a flexible solution for designers needing a single chip to implement various DC-DC converter types. The HV version extends the input voltage tolerance compared to standard variants. It is widely used in applications where board space is limited and multiple voltage rails are required from a common source.
Replacement Considerations
LT1373HVCS8#PBF is the tube-packaged equivalent of this tape-and-reel component. LT1373HVCN8#PBF offers the same electrical specifications but in an 8-PDIP through-hole package. Verify pinout compatibility before substituting between package types.
