L4981AD013TR ST Power Factor Correction IC | 20-SOIC | 10V-22V Supply, 250kHz

Product Overview

The L4981AD013TR is a high-performance Power Factor Correction (PFC) controller IC from STMicroelectronics, designed for AC-DC converters requiring low harmonic distortion and high power factor. It operates in transition mode (TM) with a fixed off-time control, enabling efficient power conversion for applications up to 250kHz. The device integrates a 1.5A totem-pole gate driver, overvoltage protection, and a precise 1% internal reference. Housed in a 20-SOIC (0.295") wide-body package, it is suitable for medium-to-high power supplies.
