LM3447MTX/NOPB TI AC-DC Controller | 14-TSSOP | Flyback, PFC

Product Overview

The LM3447MTX/NOPB is a high-performance AC-DC controller from Texas Instruments, designed for isolated flyback topologies with primary-side regulation (PSR) and power factor correction (PFC). It integrates a 700V startup FET and advanced control algorithms to achieve high efficiency, low standby power, and excellent line/load regulation. The device is housed in a compact 14-TSSOP package, making it ideal for space-constrained applications.
