LTC3862EUH-1#TRPBF

DC DC Switching Controllers Overview

The LTC3862EUH-1#TRPBF is a multi-phase current mode step-up DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 36V and supports Boost and SEPIC topologies. The device features a fixed switching frequency of 300kHz and maintains a load regulation of -2%. It functions reliably across a temperature range of -40°C to +85°C. Packaged in a 24-WQFN (5x5) surface-mount format, it provides a quiescent current of 30µA and requires a supply voltage between 3V and 5.5V.

DC DC Switching Controllers Feature Summary

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging distinct from tube variants. Confirm the 'E' grade rating aligns with the required -40°C to +85°C operating temperature range for your application environment. Cross-reference the manufacturer datasheet to ensure pinout compatibility with existing PCB footprints before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when designing multi-phase boost converters requiring precise current sharing and low quiescent current. Ensure the external MOSFET selection matches the controller's drive capabilities and thermal requirements. Verify that the desired output voltage configuration falls within the supported operational limits defined in the electrical characteristics table.

DC DC Switching Controllers Part Context

This part belongs to the LTC3862 family of synchronous boost controllers designed for high-performance power management. It complements other variants like the LTC3862IUH-1#PBF which offers an extended industrial temperature range up to +125°C. The family shares core architecture but differs in package options and thermal specifications to suit diverse deployment scenarios.

DC DC Switching Controllers Replacement Considerations

The LTC3862EUH-1#PBF serves as a direct functional alternative differing primarily in tube packaging instead of tape-and-reel. Evaluate thermal performance differences if transitioning between these package types in constrained board layouts.
