L6599AD Power Supply Controller Resonant Converter Controller 16-SO
The L6599AD is a high-voltage resonant controller from STMicroelectronics, designed to drive a half-bridge topology in zero-voltage switching (ZVS) resonant converters. It integrates high-side and low-side gate drivers with a high-voltage floating structure, enabling efficient power conversion in applications like switch-mode power supplies (SMPS) and LED drivers. A key feature is its wide input voltage range of up to 600V, which allows direct connection to a rectified mains voltage. It offers programmable oscillator frequency and dead-time, along with soft-start and controlled preheating/ignition sequences for fluorescent lamps. The device includes comprehensive protection features such as non-latching shutdown with automatic restart for overcurrent, overload, and overtemperature conditions, ensuring robust and safe operation.
The L6599AD is primarily applied in high-efficiency AC-DC converters, LCD/Plasma TV power supplies, server and telecom power systems, and electronic ballasts for fluorescent lighting. Its ability to enable ZVS operation significantly reduces switching losses and electromagnetic interference (EMI), making it ideal for compact and efficient power supply designs.
