LT3686AHMSE#PBF

Overview

The LT3686AHMSE#PBF is a synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6 V to 37 V and delivers up to 1.2 A output current. The device features an adjustable output voltage starting from 0.8 V, with a maximum output capability of 37 V. It supports switching frequencies between 300 kHz and 2.5 MHz. The quiescent current is specified at 1.1 mA during operation. The component is housed in a 12-TSSOP package with an exposed pad, designed for surface-mount installation.

Feature Summary

Synchronous buck topology for high efficiency
Wide input voltage range supporting 37V sources
Adjustable output voltage down to 0.8V
Programmable switching frequency from 300kHz to 2.5MHz

Applications

Industrial control systems
Distributed power architectures
Battery-powered equipment
Embedded computing platforms

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with PCB footprint requirements for the 12-TSSOP exposed pad configuration. Cross-reference datasheet revisions for any updates to electrical characteristics or thermal performance data before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring wide input voltage tolerance up to 37V. Consider the adjustable output range if system voltages vary. Evaluate thermal dissipation needs due to the exposed pad design. Confirm that the required switching frequency falls within the programmable range to optimize filter component sizes and efficiency.

Part Context

This part belongs to the LT3686 series of high-voltage synchronous buck regulators. It shares architectural similarities with other devices in the family but differs in specific package options and thermal characteristics. The HMSE variant specifically denotes the 12-TSSOP package form factor, distinguishing it from DFN versions like the IDD.
