LM5115AMTX Equivalent & Substitute Parts

Part Overview

The LM5115AMTX is a secondary-side power supply controller manufactured by Texas Instruments, designed for isolated power conversion applications. It operates across an input voltage range of 5V to 30V with a supply voltage of 5V to 7.5V and a supply current of 4 mA. The device is housed in a 16-TSSOP surface mount package and supports operating temperatures from -40°C to 125°C.

The LM5115AMTX carries an Obsolete product status, which necessitates identifying functionally equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain identical electrical specifications, mechanical compatibility, and package configuration to ensure direct replacement capability.
