LTC3862HUH-2#TRPBF

DC DC Switching Controllers Overview

The LTC3862HUH-2#TRPBF is a dual-phase current mode step-up DC/DC controller manufactured by Analog Devices Inc. It supports Boost and SEPIC topologies with an input voltage range of 5.5 V to 36 V. The device operates at a switching frequency of 300 kHz and features a quiescent current of 30 uA. It is housed in a 24-lead QFN package rated for industrial temperatures from -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Supports multi-phase operation for high-current boost and SEPIC applications
• Features low static current for improved efficiency in standby modes
• Includes integrated soft-start and phase control capabilities

DC DC Switching Controllers Applications

• Industrial power distribution systems
• Battery-powered equipment requiring voltage step-up
• Telecommunications infrastructure power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm that the HUH variant meets the required thermal performance for your enclosure. Ensure compatibility with the intended switching frequency and phase count configuration before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring dual-phase boost conversion within a 5.5 V to 36 V input window. Compare against the EUH variant if lower temperature ratings are acceptable. Consider the QFN package footprint constraints and thermal pad requirements during PCB layout planning.

DC DC Switching Controllers Part Context

This part belongs to the LTC3862 family of synchronous step-up controllers. It shares functional similarities with other members like the LTC3862EUH-2 but differs in package type and operating temperature range. The series is designed for efficient power management in compact form factors.

DC DC Switching Controllers Replacement Considerations

The LTC3862EUH-2#PBF serves as a pin-compatible alternative with a different package and temperature rating. Verify thermal dissipation requirements when substituting between QFN and SSOP variants.
