LTC3824EMSE#PBF

DC DC Switching Controllers Overview

The LTC3824EMSE#PBF is a high voltage step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 60 V and supports adjustable output voltages from 800 mV to 60 V. The device provides a single output capable of driving external power stages up to 5 A. It features a switchable frequency between 200 kHz and 600 kHz and maintains a low quiescent current of 40 uA. Designed for surface mount installation, it utilizes a 10-MSOP package with exposed pad and functions within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS standards before procurement. Confirm the MSOP-10 package dimensions match your PCB footprint requirements. Ensure the external component selection aligns with the 4 A to 60 V operational limits defined in the official datasheet. Check for any recent production change notices regarding material or bonding wire updates.

DC DC Switching Controllers Selection Notes

Select this controller when a wide input voltage range up to 60 V is required for buck conversion. It is appropriate for designs utilizing external P-channel MOSFETs rather than integrated synchronous rectification. Consider the 10-MSOP package constraints for thermal management and board space. Verify that the external components can handle the specified 5 A output current capability.

DC DC Switching Controllers Part Context

This component belongs to the LTC3824 series of high voltage step-down controllers. It is distinct from other Analog Devices regulators by its specific focus on driving external P-channel devices. The EMSE designation indicates the commercial temperature grade and MSOP packaging variant within the broader product family.
