LT1936HMS8E

Overview

The LT1936HMS8E is a high-efficiency, synchronous step-down DC-to-DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7V to 17V and delivers up to 1A of output current. The device supports fixed switching frequencies of 1MHz or 2.25MHz, with a synchronization capability allowing adjustment within ±40% of the nominal frequency. It features ultra-low quiescent current for improved light-load efficiency and maintains high efficiency across a wide output voltage range. The component is housed in an 8-lead MSOP package with an exposed pad for thermal management.

Feature Summary

Synchronous rectification architecture ensures high conversion efficiency across varying load conditions
Ultra-low quiescent current operation optimizes power consumption during light-load scenarios
Flexible switching frequency selection with external synchronization support reduces electromagnetic interference

Applications

Portable battery-powered equipment requiring extended runtime
Embedded systems with strict power budget constraints
Industrial control modules needing stable regulated voltage rails

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm temperature grade and packaging configuration. Ensure that the procurement channel provides traceability to the original manufacturer. Cross-reference the part number with the latest datasheet revisions to account for any material declaration updates or pinout modifications before finalizing supply chain agreements.

Selection Notes

Select this component when designing circuits that require a compact solution with high efficiency at moderate current levels. The availability of multiple switching frequencies allows designers to optimize for either size or noise performance. Consider the thermal requirements of the MSOP package and ensure adequate PCB copper area is allocated for the exposed pad to maintain reliable operation under continuous load.

Part Context

This part belongs to the LTC3621 family of synchronous buck regulators, designed for applications demanding high efficiency and low standby power. The 'H' suffix typically denotes an extended industrial temperature range variant compared to standard commercial grades. It serves as a core power management element in systems where space is limited and power integrity is critical for system stability.
