LTC3862IFE#PBF

DC DC Switching Controllers Overview

The LTC3862IFE#PBF is a multi-phase current mode step-up DC/DC controller manufactured by Analog Devices Inc. It supports Boost and SEPIC topologies within an input voltage range of 8.5 V to 36 V. The device operates with a fixed switching frequency of 300 kHz and features a low static current of 30 uA. It is housed in a TSSOP-EP-24 package and functions across an industrial temperature range from -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Supports multiphase boost and SEPIC converter topologies for high-power applications
• Integrates clock synchronization capability for system-wide noise reduction
• Includes programmable soft-start functionality to limit inrush current
• Features phase control for optimized current sharing among phases

DC DC Switching Controllers Applications

• High power density point-of-load conversion systems
• Industrial equipment requiring wide input voltage ranges
• Telecommunications infrastructure power supplies
• Distributed power architectures utilizing boost converters

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation, as variations exist between commercial and extended temperature grades. Confirm availability status through authorized distributors, as supply constraints may apply. Ensure the selected package matches the required PCB footprint and thermal management strategy for the target application environment.

DC DC Switching Controllers Selection Notes

Select this component when designing multiphase boost converters requiring precise current sharing and synchronization capabilities. Consider the 300 kHz fixed frequency for balancing efficiency and component size. Evaluate the thermal performance of the exposed pad TSSOP-24 package against the expected power dissipation levels in the final design configuration.

DC DC Switching Controllers Part Context

This part belongs to the LTC3862 family of multiphase controllers designed for high-efficiency step-up conversions. It complements other variants like the LTC3862EFE which shares similar electrical characteristics but differs in operating temperature specifications. The series targets demanding applications requiring scalable power delivery through parallel phase operation.

DC DC Switching Controllers Replacement Considerations

The LTC3862EFE-1#PBF serves as a verified alternative within the same family, offering identical electrical parameters but rated for a commercial temperature range of -40°C to +85°C instead of the extended grade.
