LTC3862EFE#PBF

DC DC Switching Controllers Overview

The LTC3862EFE#PBF is a synchronous step-up DC/DC controller manufactured by Analog Devices Inc., designed for high-efficiency power conversion in compact spaces. It operates within an input voltage range of 4V to 36V and supports switching frequencies from 75kHz to 500kHz. The device utilizes a 24-TSSOP package with exposed pad for thermal management. Key electrical specifications include a maximum duty cycle of 96% and operation across a temperature range of -40°C to 85°C. It features two output stages and supports boost and SEPIC topologies, providing flexible control options including phase control and soft start.

DC DC Switching Controllers Feature Summary

• Supports boost and SEPIC converter topologies for versatile voltage step-up applications
• Enables precise current sharing through multi-phase synchronization capabilities
• Integrates comprehensive protection and control features including soft start and frequency control

DC DC Switching Controllers Applications

• Industrial equipment requiring isolated or non-isolated step-up power regulation
• Battery-powered systems needing efficient voltage boosting from low source voltages
• Telecommunications infrastructure utilizing standard bus voltage levels

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to ensure correct pinout and functional configuration. Confirm that the 24-TSSOP package variant matches your PCB footprint requirements. Check for any recent product change notices regarding epoxy or wire changes that may affect long-term availability or reliability. Ensure compatibility with your system's thermal design given the exposed pad requirement.

DC DC Switching Controllers Selection Notes

Select this component when designing single-output boost converters requiring wide input voltage ranges up to 36V. Consider the 75kHz to 500kHz adjustable frequency range for optimizing inductor size versus efficiency trade-offs. Evaluate the 24-TSSOP package constraints for thermal dissipation in dense layouts. Compare against other series members if multiple outputs or different input thresholds are required.

DC DC Switching Controllers Part Context

This part belongs to the LTC3862 family of synchronous step-up controllers from Analog Devices. It is distinct from the LTC3862EFE-1#PBF and LTC3862EFE-2#PBF variants, which specify different minimum input voltage thresholds (8.5V and 5.5V respectively). The base model supports a broader lower input range starting at 4V, offering greater flexibility for low-voltage battery sources.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include LTC3862EFE-1#PBF and LTC3862EFE-2#PBF, provided the input voltage constraints align with the application. Verify pin-to-pin compatibility and thermal performance similarities before swapping.
