LTC3862EGN#TRPBF

DC DC Switching Controllers Overview

The LTC3862EGN#TRPBF is a two-phase, fixed-frequency current mode boost and SEPIC controller manufactured by Analog Devices Inc. It drives N-channel power MOSFETs to support high-efficiency DC/DC conversion. The device operates with a supply voltage range of 4V to 36V and features an adjustable switching frequency from 75kHz to 500kHz. It utilizes a 24-SSOP package with exposed pad for thermal performance. Key control features include clock synchronization, phase control, soft start, and enable functionality, designed for applications requiring reduced input and output capacitance through multiphase operation.

DC DC Switching Controllers Feature Summary

• Two-phase operation reduces system input and output filtering requirements
• Fixed frequency peak current mode control architecture
• 10V gate drive capability optimized for high voltage MOSFETs
• Supports clock synchronization and phase shifting for parallel operation

DC DC Switching Controllers Applications

• High power density point-of-load (POL) converters
• Industrial equipment power distribution systems
• Telecommunications infrastructure power supplies
• Automotive electronics requiring robust voltage regulation

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the manufacturer is Analog Devices Inc. to ensure authenticity. Check for RoHS compliance markings as indicated by the PBF suffix in related part numbers within the family. Ensure the SSOP-24 package type matches your PCB footprint requirements before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring multiphase boost or SEPIC topologies where input ripple reduction is critical. The 10V gate drive suits high-voltage MOSFET applications better than lower drive variants. Consider the 75kHz to 500kHz frequency range for balancing efficiency and passive component size. Ensure the 4V to 36V Vcc range aligns with your system's available rail voltages.

DC DC Switching Controllers Part Context

This part belongs to the LTC3862 family of controllers, which are designed for high-performance step-up and SEPIC conversions. The family includes variants like the LTC3862EFE and LTC3862EGN, differing primarily in package type and reel configuration. These controllers are engineered to replace single-phase solutions in high-current applications by distributing load across multiple phases.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other LTC3862 variants such as LTC3862EFE#PBF or LTC3862EGN#PBF, depending on required packaging. Verify pin compatibility and electrical specifications match exactly. Cross-reference with LTC3863 series only if buck topology is acceptable, though functional differences exist.
