L6591TR ST Resonant Controller | 16-SO | 50% Duty Cycle, 600V Half-Bridge

Product Overview

The L6591TR is a high-voltage resonant controller from STMicroelectronics, designed for half-bridge resonant topologies. It integrates a 600V half-bridge driver with a 50% fixed duty cycle and operates at frequencies up to 500kHz. The device is optimized for LLC resonant converters, offering high efficiency and low EMI. Housed in a compact 16-SO package, it is ideal for power supplies requiring high power density.
