Product Introduction

Overview

The STNRG012TR, produced by STMicroelectronics, is a digital combo multi-mode PFC (Power Factor Correction) and time-shift LLC (Inductor-Inductor-Capacitor) resonant half-bridge controller. This device is designed to manage both AC and DC input lines, making it versatile for various high-efficiency power conversion applications. It integrates a multi-mode PFC controller, a high-voltage double-ended controller for LLC resonant half-bridge, and an 800 V-rated start-up generator. The STNRG012TR is optimized for compliance with stringent energy-saving regulations and is particularly suited for applications requiring advanced power management and high efficiency.
