LT1912EMSE#PBF

Overview

The LT1912EMSE#PBF is a monolithic high voltage step-down switching regulator manufactured by Analog Devices Inc. It operates from an input voltage range of 4V to 60V and delivers up to 1A of output current. The device integrates a 60V N-channel power switch, enabling a compact solution with minimal external components. Key electrical parameters include a quiescent current of 35µA and a fixed internal switching frequency of 500kHz. It features adjustable soft-start, cycle-by-cycle current limiting, and thermal shutdown protection.

Feature Summary

• Integrates a high-voltage N-channel power switch for simplified design
• Provides precise current limit and thermal shutdown protection
• Features adjustable soft-start capability to manage inrush current

Applications

• Industrial point-of-load regulation
• Automotive electronics systems
• Distributed power architectures

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the MSOP-10 package type matches your PCB footprint requirements. Ensure the supplier provides valid traceability documentation for Analog Devices Inc. products to guarantee authenticity and quality control.

Selection Notes

Select this component when input voltages exceed standard 36V regulators but remain below 60V. It is suitable for applications requiring moderate output currents up to 1A without external pass transistors. Consider the fixed 500kHz frequency for EMI planning and inductor size optimization compared to variable frequency alternatives.

Part Context

This part belongs to the LT1912 family of high-voltage DC/DC converters. It shares functional similarities with other Linear Technology (now Analog Devices) buck regulators like the LT1911 and LT1913, differing primarily in input voltage ranges and maximum output current capabilities within the same MSOP-10 package form factor.

Replacement Considerations

LT1912EMS#PBF is the tape-and-reel equivalent of the tube-packaged LT1912EMSE#PBF. Cross-reference with LT1911 or LT1913 variants if input voltage or current requirements differ. Verify pin compatibility before substituting with non-Analog Devices equivalents.
