LT8336HV#PBF

Overview

The LT8336HV#PBF is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It features a 40V switch rating and delivers up to 2.5A of output current. The device operates with low quiescent current and utilizes a silent switching architecture to minimize electromagnetic interference. It supports input voltages ranging from 2.8V to 40V and can generate regulated outputs up to 60V. The component is housed in a thermally enhanced DFN-10 package, suitable for surface-mount applications.

Feature Summary

• Silent switching technology reduces electromagnetic interference emissions
• Synchronous rectification improves conversion efficiency
• Low quiescent current operation extends battery life
• Integrated 40V high-side switch handles elevated input voltages

Applications

• Battery-powered portable equipment requiring efficient voltage boosting
• Industrial control systems utilizing single-cell lithium-ion batteries
• Automotive electronics operating within wide input voltage ranges
• Communication infrastructure power supplies

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the DFN-10 package availability through authorized distributors. Ensure the supplier provides valid RoHS documentation. Check for any recent product change notices affecting thermal performance or pinout compatibility before finalizing procurement orders.

Selection Notes

Select this component when input voltages exceed standard boost converter limits but remain below 40V. Consider the 2.5A current capability for moderate load requirements. Evaluate the silent switching feature if acoustic noise or EMI sensitivity is critical. Compare against lower voltage variants if system input does not require the extended 40V headroom provided by the HV version.

Part Context

This part belongs to the LT8336 family of high-voltage synchronous boost converters. It shares architectural similarities with other members like the LT8362 but differs in switch voltage ratings and current capabilities. The family targets applications needing reliable power conversion from single-cell sources in compact form factors.

Replacement Considerations

LT8336: Lower voltage rating variant; verify if 40V input tolerance is required.
