Overview
The LT8338JMSE#TRPBF is a micropower synchronous boost converter manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 40 V and delivers up to 2.5 A output current. The device features a low quiescent current of 12 uA and supports switching frequencies from 300 kHz to 3 MHz. It is housed in a 10-lead MSOP package and functions within a temperature range of -40°C to +150°C junction temperature.
Feature Summary
- Synchronous rectification for improved efficiency
- Silent Switch architecture to minimize radiated noise
- Low quiescent current operation for battery applications
- Integrated shutdown control
Applications
- Battery-powered portable equipment
- Industrial sensor interfaces
- Telecommunications systems
- Automotive electronics
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the JMSE variant meets the required thermal and electrical specifications for the target application environment. Ensure compatibility with the intended PCB footprint and soldering process for the MSOP-10 package.
Selection Notes
Select this component for designs requiring high efficiency at light loads due to its low IQ. Consider the wide input voltage range suitable for single-cell lithium or multi-cell alkaline batteries. Evaluate the silent switch feature if EMI constraints are strict in the system layout.
Part Context
This part belongs to the LT8338 series of micropower synchronous boost converters. It is designed to provide regulated output voltages higher than the input supply. The series emphasizes energy conservation and noise reduction in compact form factors.
Replacement Considerations
Check for direct pin-compatible alternatives within the Analog Devices portfolio that match the 2.5 A current rating and 40 V input limit. Verify equivalent switching frequency ranges and quiescent current specifications before substitution.
