L6599DTR ST AC-DC Controllers

The L6599DTR is a double-ended controller for resonant half-bridge DC-DC converters from STMicroelectronics, specifically optimized for soft-switching topologies such as the LCC or LLC resonant converters. For selection, verify the high-voltage startup capability (up to 600V on the HV pin), precise oscillator for operating frequency control, built-in dead-time management, and burst mode operation for standby power reduction. Features include two high-current gate drivers for external MOSFETs, non-latching overcurrent protection, frequency shift protection against transformer saturation, and automatic restart for overvoltage protection. Operating temperature from -40°C to +150°C. Applications include 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.
