LTC3892HUH-2#TRPBF

DC DC Switching Controllers Overview

The LTC3892HUH-2#TRPBF is a dual synchronous step-down DC/DC switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4.5V to 60V and features two independent output channels. The device supports switching frequencies between 105kHz and 835kHz for the first channel, and 350kHz to 535kHz for the second. It utilizes a 32-WFQFN (5x5) package with exposed pad and functions within a junction temperature range of -40°C to 125°C.

DC DC Switching Controllers Feature Summary

• Drives all N-channel synchronous power MOSFET stages for high efficiency
• Minimizes power loss and noise through out-of-phase operation of controller output stages
• Includes integrated control features such as current limit, enable, frequency control, power good, soft start, and tracking

DC DC Switching Controllers Applications

• High efficiency dual-phase step-down converters
• Systems requiring 8V gate drive capabilities
• Dual output DC/DC conversion designs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'HUH' indicates the required thermal and electrical characteristics for your application. Confirm that the '#TRPBF' designation matches the tape and reel packaging requirement. Ensure the component meets the specified operating temperature range and input voltage limits before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this controller when a wide input voltage range up to 60V is required for dual output buck applications. Consider the 8V gate drive specification if driving specific low-threshold N-channel MOSFETs. Evaluate the out-of-phase operation benefits for noise reduction in sensitive environments compared to in-phase alternatives.

DC DC Switching Controllers Part Context

This component belongs to the LTC3892 family of dual output synchronous step-down controllers. It shares core functionality with variants like the LTC3892EUH-2 and LTC3892IUH-2, differing primarily in thermal performance and gate drive specifications associated with the HUH suffix. The family supports various topologies including buck and SEPIC configurations.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other members of the LTC3892 family such as the LTC3892EUH-2#TRPBF or LTC3892IUH-2#TRPBF, provided their specific gate drive voltages and thermal ratings align with the design requirements. Verify pin compatibility and control feature parity.
