L6599ADTR
STMicroelectronicsL6599ADTR is an STMicroelectronics improved high-voltage resonant controller in SO-16, tape and reel — for LLC resonant half-bridge power supplies in adapters, flat-panel displays and industrial SMPS: 50% complementary duty cycle with variable-frequency control up to 500 kHz, and a 600 V-rail compatible high-side gate driver with integrated bootstrap diode and high dv/dt immunity. Two-level overcurrent protection (frequency shift first, latched shutdown second), burst-mode operation at light load and a PFC-controller interface is the selection point: a proven single-chip control core for efficient resonant converters with fewer external parts. Selection advice: the A revision supersedes the original L6599 with improved protection behavior — check the datasheet revision notes before treating it as a drop-in on legacy L6599 boards; the DTR suffix is the SO-16 tape-and-reel variant, while the N-suffix code is the DIP-16 through-hole option. Parameters verified against the STMicroelectronics official store listing, which shows the L6599A family Active.
