LTC3864MPMSE#PBF

DC DC Switching Controllers Overview

The LTC3864MPMSE#PBF is a high-performance step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 3.5V to 60V and supports adjustable switching frequencies from 50kHz to 850kHz. The device features a maximum duty cycle of 100% and is housed in a 12-MSOP-EP package. It provides control characteristics including current limiting, enable functionality, frequency control, power good indication, and soft start capabilities.

DC DC Switching Controllers Feature Summary

• Supports 100% duty cycle operation for minimal dropout voltage requirements
• Enables flexible design through programmable switching frequency adjustment
• Integrates comprehensive protection and monitoring via current limit, enable, and power good signals

DC DC Switching Controllers Applications

• Industrial point-of-load regulation
• Telecommunications power distribution systems
• Embedded computing power management

DC DC Switching Controllers Procurement Notes

Verify the specific MP suffix grade against official Analog Devices documentation to confirm extended temperature ratings and reliability specifications. Ensure the 12-MSOP-EP package footprint matches the target PCB layout. Confirm RoHS compliance status through the manufacturer's latest material declaration before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when designing buck converters requiring wide input voltage compatibility up to 60V. The adjustable frequency range allows optimization for efficiency or size constraints. Verify that the required thermal performance aligns with the MSOP-EP package capabilities under expected load conditions.

DC DC Switching Controllers Part Context

This part belongs to the LTC3864 family of high-voltage synchronous step-down controllers. It shares core architecture with variants like the LTC3864EMSE#PBF but differs in military-grade temperature specifications. The M suffix typically denotes enhanced performance or reliability standards compared to commercial grade equivalents within the same product line.

DC DC Switching Controllers Replacement Considerations

LTC3864EMSE#PBF serves as a commercial-grade alternative with identical pinout and electrical functions but lower temperature limits. LTC3864HMSE#PBF offers industrial temperature range coverage. Cross-reference datasheets to ensure thermal and operational boundaries meet application requirements.
