L6599ATDTR ST AC-DC Controllers

The L6599ATDTR is a double-ended controller for resonant half-bridge DC-DC converters from STMicroelectronics in SO-16 package, specifically optimized for soft-switching topologies such as LLC resonant converters. For selection, verify high-voltage startup capability (up to 600V on HV pin), precise oscillator for operating frequency control, built-in dead-time management, burst mode operation for standby power reduction, and operating temperature from -40°C to +150°C. Features include two high-current gate drivers for external MOSFETs, non-latching overcurrent protection, frequency shift protection against transformer saturation, automatic restart for overvoltage protection, and adaptive dead-time control. Ideal for high-efficiency AC-DC power supplies (silver-box or open-frame), LCD/PDP TV power supplies, desktop computer and server PSUs, battery chargers for electric vehicles and power tools, and any medium-to-high power converter requiring high efficiency through zero-voltage switching (ZVS) with low EMI signature.
