LT8336HV#WTRPBF

Overview

The LT8336HV#WTRPBF is a synchronous step-up DC/DC converter featuring a 40V input range and an integrated 2.5A power switch. It operates with low quiescent current to maximize efficiency in battery-powered applications. The device utilizes a constant frequency architecture that allows for the use of small external components, including inductors and capacitors. It incorporates silent switching technology to minimize electromagnetic interference (EMI) during operation. The controller supports adjustable output voltage via an external resistor divider and includes protection features such as thermal shutdown and cycle-by-cycle current limiting.

Feature Summary

• Synchronous rectification provides high conversion efficiency across varying load conditions.
• Silent switching architecture reduces radio frequency noise and electromagnetic interference emissions.
• Integrated 2.5A power switch eliminates the need for external Schottky diodes.
• Low quiescent current consumption extends battery life in portable equipment.

Applications

• Battery-powered portable instrumentation
• Industrial sensor nodes
• Medical devices requiring low noise power supplies
• Automotive electronics operating within specified voltage ranges

Procurement Notes

Verify the specific suffix #WTRPBF against the manufacturer's official datasheet to confirm package type and reel specifications. Ensure compatibility with your PCB footprint and reflow profile requirements. Cross-reference the part number with Analog Devices documentation to validate pinout configuration and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a compact solution is required for stepping up low battery voltages to higher system rails. Consider the 40V maximum input limit and 2.5A continuous current capability relative to your peak load demands. Evaluate the trade-off between EMI performance provided by silent switching and standard switching frequencies based on your application's sensitivity to noise.
