LM3447MTE/NOPB TI AC-DC Controller | 14-TSSOP | 8-Pin, 0.5A Gate Drive

Product Overview

The LM3447MTE/NOPB is a high-performance AC-DC controller from Texas Instruments, designed for isolated flyback and buck-boost topologies. It integrates a 0.5A gate driver and operates from 8V to 18V input voltage. The device features primary-side regulation (PSR) eliminating the need for an optocoupler, reducing component count and cost. Housed in a 14-pin TSSOP package, it is ideal for compact power supplies.
