Overview
The LT1176CSW#TRPBF is a switching regulator IC manufactured by Analog Devices Inc., housed in a 16-SOIC (0.295, 7.50mm Width) surface-mount package. It operates as a versatile DC-DC converter supporting Buck, Boost, Flyback, and Inverting topologies with an adjustable output voltage range of 1.23V to 40V. The device features a fixed switching frequency of 100kHz and supports input voltages from 8V to 35V. It provides a switch current capability of 1.2A and includes internal compensation for stable operation across various configurations.
Feature Summary
- Supports multiple power conversion topologies including buck, boost, flyback, and inverting circuits within a single integrated circuit.
- Features internal frequency compensation to simplify external component selection and ensure stability across different operating modes.
- Provides adjustable output voltage control allowing flexible design integration for diverse application requirements.
Applications
- Buck step-down voltage regulation
- Boost step-up voltage regulation
- Flyback isolated power supply designs
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the C grade temperature rating aligns with your operational environment requirements. Ensure the 16-SOIC footprint matches your PCB layout specifications before finalizing procurement orders.
Selection Notes
Select this component when designing non-isolated or isolated converters requiring a 100kHz switching frequency. It is suitable for applications needing up to 1.2A switch current with adjustable output settings. Consider the SOIC package size constraints and thermal dissipation capabilities during the initial hardware architecture phase.
Part Context
This part belongs to the LT1176 family of high-efficiency switching regulators. It shares core functional characteristics with other variants like the LT1176CN8 but differs in package type and manufacturing lot specifications. The series is known for its versatility in handling various DC-DC conversion tasks efficiently.
Replacement Considerations
LT1176CN8#PBF offers identical electrical performance in a PDIP package. LT1176CS#PBF provides the same functionality in a standard SOIC package without the reel specification. Verify pin compatibility and thermal characteristics when substituting these variants.
