Overview
The LT1576CS8-SYNC#TRPBF is a buck switching regulator IC from Analog Devices Inc. It provides a positive adjustable output voltage with a maximum current of 1.5A. The device operates within an input voltage range of 5V to 25V and features a fixed switching frequency of 200kHz. It is housed in a compact 8-pin SOIC package with a width of 3.90mm, designed for surface mount technology (SMD/SMT) installation.
Feature Summary
- Integrates a 1.5A switch for efficient step-down voltage conversion
- Features a fixed 200kHz switching frequency for optimized component size
- Supports positive adjustable output voltage regulation
Applications
- Industrial power supply systems
- Distributed power architectures
- Battery-powered equipment requiring regulated lower voltages
Procurement Notes
Verify the specific suffix SYNC against official Analog Devices documentation to confirm synchronization capabilities or pinout variations. Ensure the order matches the exact part number LT1576CS8-SYNC#TRPBF to avoid compatibility issues with existing PCB layouts. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement.
Selection Notes
Select this component when a 1.5A output current is required from an input range of 5V to 25V. The 200kHz frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Consider the 8-SOIC package constraints for thermal management and board space availability during the design phase.
Part Context
This part belongs to the LT1576 family of high-efficiency switching regulators. It shares architectural similarities with other LT1576 variants but includes specific SYNC designation attributes. The family is known for combining high efficiency with a compact footprint, suitable for applications where space and performance are critical constraints.
Replacement Considerations
LT1576CS8#TRPBF is a related variant within the same product line. Verify functional equivalence regarding synchronization features and output specifications before substitution.
