L6599ADTR ST AC-DC Controllers

The L6599ADTR is an improved version of the L6599, offering a double-ended resonant half-bridge controller with enhanced performance and additional features. For selection, verify the high-voltage startup (600V rating on HV pin), adaptive dead-time management for optimizing soft-switching across load range, precise operating frequency control (up to 500kHz), and latched or auto-restart protection modes for overcurrent, overvoltage, and feedback disconnection. Key enhancements include improved UVLO management and integrated bootstrap driver with dedicated synchronous high-voltage floating section. Applications include high-density power supplies for LCD/LED TVs, high-power AC-DC adapters, telecom rectifiers, industrial power conversion (welding equipment, plasma cutters), and server power supply units requiring wide load efficiency, low EMI, and compact design. The device is designed for converters from 100W to 1000W+ where resonant topology efficiency is crucial. In stock at HL Electronics – request a quote for fast delivery.
