Overview
The LT1176CSW-5#TRPBF is a switching regulator IC manufactured by Analog Devices Inc. It functions as a buck or flyback DC-to-DC converter with an adjustable output voltage range from 2.21V to 31.5V. The device integrates a 1.2A switch and operates at a fixed switching frequency of 100kHz. It supports both positive and negative output configurations and is housed in a 16-pin SOIC package.
Feature Summary
- Integrates a high-current 1.2A power switch for efficient power conversion
- Supports flexible topology options including buck and flyback configurations
- Provides adjustable output voltage capability across a wide range
Applications
- General-purpose DC-to-DC power supply systems
- Industrial equipment requiring isolated or non-isolated regulation
- Embedded systems needing compact voltage step-down solutions
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm the -5 variant corresponds to the correct electrical specifications for your design requirements. Check current availability status as distribution may be limited. Ensure compatibility with your PCB footprint for the SOIC-16 package before finalizing procurement orders.
Selection Notes
Select this component when a single-chip solution for buck or flyback conversion is required. It is suitable for designs needing up to 1.2A output current without external pass transistors. Consider the 100kHz switching frequency for EMI management and filter size trade-offs. Verify input voltage ranges do not exceed the 35V maximum rating for reliable operation.
Part Context
This part belongs to the LT1176 family of switching regulators from Analog Devices. The family includes variants with different packages and fixed/adjustable output options. The CSW designation typically refers to the commercial temperature grade and SOIC-16 package type within this product line.
Replacement Considerations
LT1176CSW-5#PBF is a tube-packaged version of the same electrical device. LT1176CN8#PBF offers similar functionality in a PDIP package. Verify pinout compatibility and thermal performance when substituting between package types.
